It analyzes the results of the power flow simulations and provides the operator with the summary of this analysis. It further provides other applications with pseudo-measurements for each distribution system element from within substations down to load centers in the secondaries. The model is kept up-to-date by real-time updates of topology, facilities parameters, load, and relevant components of the transmission system. The Distribution Operation Modeling and Analysis supports three modes of operation: 1. Real-time mode, which reflects present conditions in the power system. 2. Look-ahead mode, which reflects conditions expected in the near future (from one hour to one week ahead) 3. Study mode, which provides the capability of performing the what if studies. The key sub-s performed by the application are as follows: Volume II D29-7 Final Release

12 Modeling Transmission/Sub-Transmission Immediately Adjacent to Distribution Circuits This sub- provides topology and electrical characteristics of those substation transformers and transmission/sub-transmission portions of the system, where loading and voltage levels significantly depend on the operating conditions of the particular portion of the distribution system. The model also includes substation transformers and transmission/sub-transmission lines with load and voltage limits that should be respected by the application Modeling Distribution Circuit Connectivity This sub- provides a topological model of distribution circuits, starting from the distribution side of the substation transformer and ending at the equivalent load center on the secondary of each distribution transformer. A topological consistency check is performed every time connectivity changes. The model input comes from SCADA/EnergyManagement, DistributionSCADA, from field crews, from DISCO operator, from AM/FM/GIS, WorkManagement, and OutageManagement databases, and engineers. Data Management Issues between AM/FM/GIS and AdvancedDistributionAutomation Distribution Connectivity Database Standard interfaces between different AM_FM_GISDatabases, data converters, and AdvancedDistributionAutomation database are not developed yet for practical use. The AM_FM_GISDatabases were not designed for real-time operational use. They lack many objects and attributes needed for AdvancedDistributionAutomation. The population of the databases is not supported by an interactive consistency check. The existing extractors of data and the converters into AdvancedDistributionAutomation databases do not determine all data errors. The AdvancedDistributionAutomation applications must conduct additional data consistency checking and data corrections before recommendations and controls are issued. Typically utility do not have established procedures for regular update of the AM_FM_GISDatabases by the operation and maintenance personnel. Therefore many changes implemented in the field remain unnoticed by the databases. Synchronization of the field state with the AdvancedDistributionAutomation database is a challenge in modern utilities. Data Management Issues between CIS and AM/FM/GIS and AdvancedDistributionAutomation Distribution Connectivity Database For the AdvancedDistributionAutomation applications, the AM/FM/GIS data must be associated with the corresponding customer information data from the CIS database. This data include billing data and description of the customer specifics, such as rate schedule, customer code, meter number, address, etc. The critical information is the billing data. This data is updated based on metering cycles (typically one month) and is not well synchronized. In order to synchronize billing data an automated meter reading system should be implemented. In order to update the AdvancedDistributionAutomation databases more frequently, which would increase the resolution of AdvancedDistributionAutomation s to individual distribution transformers and even customers, a high capacity communication system should be introduced to gather the data from hundreds of thousands of meters at the same time. Some of the modern procedures enabled by AutomatedMeterReadingDevice conflict with the needs of AdvancedDistributionAutomation model.an example is the consolidated bills, where the individual load data of distribution transformers located in different sites of the consolidated company becomes unavailable for the external to CIS world. Volume II D29-8 Final Release

13 Modeling Distribution Nodal Loads This sub- provides characteristics of real and reactive load connected to secondary side of distribution transformer or to primary distribution circuit in case of primary meter customers. These characteristics are sufficient to estimate kw and kvars at a distribution node at any given time and day and include the load shapes and load-to-voltage sensitivities (for real and reactive power) of various load categories. In real-time mode, the nodal loads are balanced with real-time measurements obtained from corresponding primary circuits. A validity check is applied to real-time measurements. The load model input comes from DistributionSCADA, from CIS supported by AutomatedMeterReadingDevice and linked with AM/FM/GIS, and weather forecast systems Modeling Distribution Circuit Facilities This sub- models the following distribution circuit facilities: 1. Overhead and underground line segments 2. Switching devices 3. Substation and distribution transformers, including step-down transformers 4. Station and feeder capacitors and their controllers 5. Feeder series reactors 6. Voltage regulators (single- and three-phase) and their controllers 7. LTC s and their controllers 8. Distribution generators and synchronous motors 9. Load equivalents for higher frequency models All facilities should be modeled with sufficient details to support the required accuracy of Distribution Operation Modeling and Analysis application Distribution Power Flow The sub- models the power flow including the impact of automatically controlled devices (i.e., LTCs, capacitor controllers, voltage regulators), and solves both radial and meshed networks, including those with multiple supply busses (i.e. having Distributed Energy Resources (DER) interconnected to the power system) Evaluation of Transfer Capacity This sub- estimates the available bi-directional transfer capacity for each designated tie switch. The determined transfer capacity is such that the loading of a tie switch does not lead to any voltage or current violations along the interconnected feeders. Volume II D29-9 Final Release

14 Power Quality Analysis This sub- performs the power quality analysis by: 1. Comparing (actual) measured and calculated voltages against the limits 2. Determining the portion of time the voltage or imbalance are outside the limits 3. Determining the amount of energy consumed during various voltage deviations and imbalance 4. Recording the time when voltage violations occur 5. Performing modeling of higher harmonics propagation and resonant conditions based on information available from the sources of harmonic distortion 6. Performing modeling of rapid voltage changes based on information available from the sources of voltage distortion The sub- provides the ability to estimate the expected voltage quality parameters during the planned changes in connectivity and reactive power compensation Loss Analysis This sub- bases its analysis on technical losses (e.g., conductor I 2 R losses, transformer load and no-load losses, and dielectric losses) calculated for different elements of the distribution system (e.g., per feeder or substation transformer). For the defined area, these losses are accumulated for a given time interval (month, quarter, year, etc.). They are further compared with the difference between the energy input (based on measurements) into the defined area and the total of relevant billed kwh (obtained from the database), normalized to the same time interval. The result of the comparison is an estimate of commercial losses (e.g., metering errors and theft) Fault Analysis This sub- calculates three-phase, line-to-line-to-ground and line-to-ground fault currents for each protection zone associated with feeder circuit breakers and field reclosers. The minimum fault current is compared with protection settings while the maximum fault current is compared with interrupting ratings of breakers and reclosers. If the requirements are not met, a message is generated for the operator Evaluation of Operating Conditions This sub- determines the difference between the existing substation bus voltage and the substation bus voltages limits. The sub- also estimates the available dispatchable real and reactive load obtainable via volt/var control. The operator or other applications can use this information for selective load reduction. The sub- provides aggregated operational parameters for the transmission buses to be used in transmission operation models. Volume II D29-10 Final Release

15 1.4.3 Fault Location, Isolation and Service Restoration (FLIR) This application detects the fault, determines the faulted section and the probable location of fault, and recommends an optimal isolation of the faulted portions of the distribution feeder and the procedures for the restoration of services to its healthy portions. The key sub-s performed by the application are as follows: Fault Location This sub- is initiated by SCADA inputs, such as lockouts, fault indications/location, and, also, by inputs from OutageManagement, and, in the future, by inputs from fault-predicting devices. It determines the specific protective device, which has cleared the sustained fault, identifies the de-energized sections, and estimates the probable place of the actual or the expected fault. It distinguishes faults cleared by controllable protective devices from those cleared by fuses, and identifies momentary outages and inrush/cold load pick-up currents Fault Isolation and Service Restoration This sub- supports three modes of operation: 1. Closed-loop mode, in which the sub- is initiated by the Fault location sub-. It generates a switching order (i.e., sequence) for the remotely controlled switching devices to isolate the faulted section, and restore service to the nonfaulted sections. The switching order is automatically executed via SCADA.. 2. Advisory mode, in which the sub- is initiated by the Fault location sub-. It generates a switching order for remotely- and manually-controlled switching devices to isolate the faulted section, and restore service to the non-faulted sections. The switching order is presented to operator for approval and execution 3. Study mode, in which the sub- is initiated by the user. It analyzes a saved case modified by the user, and generates a switching order under the operating conditions specified by the user. If during execution, there is change in connectivity, the sub- interrupts the execution and re-optimizes the solution based on new conditions. If during service restoration, there is another fault, the sub- runs again considering a new fault scenario. When work is completed, the sub- is instructed to generate a switching order for restoration of the normal configuration. The generated switching orders are based on considering the availability of remotely controlled switching devices, feeder paralleling, creation of islands supported by distributed energy resources, and on cold-load pickup currents Contingency Analysis (CA) This application performs an N-m contingency analysis in the relevant portion of distribution. The runs in the following manners: 1. Periodically Volume II D29-11 Final Release

16 2. By event (topology change, load change, availability of control change) 3. Study mode, in which the conditions are defined and the application is started by the user. The application informs the operator on the status of real-time distribution system reliability Multi-level Feeder Reconfiguration (MFR) This application recommends an optimal selection of feeder(s) connectivity for different objectives. It supports three modes of operation: 1. Closed-loop mode, in which the application is initiated by the Fault Location, Isolation and Service Restoration application, unable to restore service by simple (one-level) load transfer, to determine a switching order for the remotelycontrolled switching devices to restore service to the non-faulted sections by using multi-level load transfers.. 2. Advisory mode, in which the application is initiated by SCADA alarms triggered by overloads of substation transformer, segments of distribution circuits, or by detecting an overload, or by operator who would indicate the objective and the reconfiguration area. In this mode, the application recommends a switching order to the operator. 3. Study mode, in which the application is initiated and the conditions are defined by the user. The application performs a multi-level feeder reconfiguration to meet one of the following objectives: a. Optimally restore service to customers utilizing multiple alternative sources. The application meets this objective by operating as part of Fault Location, Isolation and Service Restoration. b. Optimally unload an overloaded segment. This objective is pursued if the application is triggered by the overload alarm from SCADA, or from the Distribution Operation Modeling and Analysis, or from Contingency analysis. These alarms are generated by overloads of substation transformer or segments of distribution circuits, or by operator demand. c. Minimize losses d. Minimize exposure to faults e. Equalize voltages The last three objectives are selected by engineer/planner Relay Protection Re-coordination (RPR) This application adjusts the relay protection settings to real-time conditions based on the preset rules. This is accomplished through analysis of relay protection settings and operational mode of switching devices (i.e., whether the switching device is in a switch or in a recloser mode), while considering the real-time connectivity, tagging, and weather conditions. The application is called to perform after feeder reconfiguration, and, in case, when conditions are changed and fuse saving is required. Volume II D29-12 Final Release

17 1.4.7 Voltage and Var Control (VVC) This application calculates the optimal settings of voltage controller of LTCs, voltage regulators, DERs, power electronic devices, and capacitor statuses optimizing the operations by either following different objectives at different times, or considering conflicting objectives together in a weighted manner. It supports three modes of operation: 1. Closed-loop mode, in which the application runs either periodically (e.g., every 15 min) or is triggered by an event (i.e., topology or objective change), based on real-time information. The application s recommendations are executed automatically via SCADA control commands. 2. Study mode, in which the application performs what-if studies, and provides recommended actions to the operator. 3. Look-ahead mode, in which conditions expected in the near future can be studied (from 1 hour through 1 week) by the operator. The following objectives, which could be preset for different times of the day and overwritten by operator if need to, are supported by the application: a. Minimize kwh consumption at voltages beyond given voltage quality limits (i.e., ensure standard voltages at customer terminals) b. Minimize feeder segment(s) overload c. Reduce load while respecting given voltage tolerance (normal and emergency) d. Conserve energy via voltage reduction e. Reduce or eliminate overload in transmission lines f. Reduce or eliminate voltage violations on transmission lines g. Provide reactive power support for transmission/distribution bus h. Provide spinning reserve support i. Minimize cost of energy j. Provide compatible combinations of above objectives If, during optimization or execution of the solution, the circuit status changes, the application is interrupted and solution is reoptimized. If, during execution, some operations are unsuccessful, solution is re-optimized without involving the maling devices. If some of the controllable devices are unavailable for remote control, solution does not involve these devices but takes into account their reaction to changes in operating conditions Pre-arming of Remedial Action Schemes (RAS) This application receives pre-arming signals from an upper level of control and changes the settings (tuning parameters) of distribution-side remedial action schemes (RAS), e.g., load-shedding schemes (a component of self-healing grid) or intentional DER islanding. Volume II D29-13 Final Release

18 1.4.9 Coordination of Emergency Actions This application recognizes the emergency situation based on changes of the operating conditions or on reaction of some RAS to operational changes and coordinates the objectives, modes of operation, and constraints of other AdvancedDistributionAutomation applications. For example, Under-frequency Load Shedding Schemes trigger emergency load reduction mode of volt/var control, or the under-frequency protection of DER triggers the pre-armed intentional islanding Coordination of Restorative Actions This application coordinates the restoration of services after the emergency conditions are eliminated. For example, AdvancedDistributionAutomation changes the order of feeder re-connection based on current customer priorities or inhibits return to normal voltage until there are disconnected feeders Intelligent Alarm Processing This application analyzes SCADA and -generated alarms and other rapid changes of the operational parameters in distribution and transmission and summarizes the multiple alarms into one massage defining the root cause of the alarms. For example, multiple sudden voltage violations along a distribution feeder and overloads of some feeder segments may be caused by a loss of DER excitation, or successful reclosing of a portion of feeder with loss of significant load may be caused by miss-coordination of the recloser settings and a particular fuse protecting a loaded lateral. 1.5 Actor (Stakeholder) Roles Describe all the people (their job), systems, databases, organizations, and devices involved in or affected by the Function (e.g. operators, system administrators, technicians, end users, service personnel, executives, SCADA system, real-time database, RTO, RTU, IED, power system). Typically, these actors are logically grouped by organization or al boundaries or just for collaboration purpose of this use case. We need to identify these groupings and their relevant roles and understand the constituency. The same actor could play different roles in different Functions, but only one role in one Function.

The options for performance are selected Steps Normal Sequence Describe the normal sequence of events, focusing on steps that identify new types of information or new information exchanges or new interface issues to address. Should the sequence require detailed steps that are also used by other s, consider creating a new sub, then referring to that subroutine in this. Remember that the focus should be less on the algorithms of the applications and more on the interactions and information flows between entities, e.g. people, systems, applications, data bases, etc. There should be a direct link between the narrative and these steps. The numbering of the sequence steps conveys the order and concurrency and iteration of the steps occur. Using a Dewey Decimal scheme, each level of nested procedure call is separated by a dot.. Within a level, the sequence number comprises an optional letter and an integer number. The letter specifies a concurrent sequence within the next higher level; all letter sequences are concurrent with other letter sequences. The number specifies the sequencing of messages in a given letter sequence. The absence of a letter is treated as a default 'main sequence' in parallel with the lettered sequences.

For example, if a purchase order is exchanged in an activity, its precondition to the activity might be filled in but unapproved. Actor///Contract Preconditions or Assumptions The same as for The same as for AdvancedDistributionAutomation: Fault Location Preconditions: DistributionSCADA with fault detectors, Distribution Fault Location Isolation and Service Operation Model and Analysis with fault analysis, fault location relays (schemes) including high Restoration (FLIR) impedance relays and Some Distributed Intelligence schemes and Trouble call system exist. Fault Isolation and Service Restoration Preconditions: DistributionSCADA with ability to control a defined number of switching devices, Fault Location, Distribution Operation Model and Analysis, Voltage and Var Control for adjusting voltage and var after reconfiguration. Supervisory and closed-loop control of switches are available. Some Distributed Intelligence schemes exist. OutageManagement Outage Management is interfaced with SCADA and AdvancedDistributionAutomation and supports a dynamic topology model. EnergyManagement (WAMACS) EnergyManagement is interfaced with WAMACS and AdvancedDistributionAutomation and provides phasor data for all distribution (reference) buses. has AdvancedDistributionAutomation GUI and uses it for supervisory control of switches, for entering pseudo-scada statuses, selecting isolation and restoration alternatives, etc. The operator also has the ability to communicate with the field crews via mobile communications and computing. FieldPersonnel Distributed Intelligence Schemes AdvancedDistributionAutomationSyst em: Prearming of Remedial Action Schemes application Historic DB FieldPersonnels are able to communicate with the operator via mobile communications and computing DIS team members are able to operate in a coordinated manner based on peer-to-peer communications or based on operational parameters, and DIS team masters are able to communicate via fast peer-topeer communications The pre-arming application downloads operating conditions to DIS masters based on results Historic database is able to store large amount of data about outages, which will be used by the outage Volume II D29-64 Final Release

Environmental daily data collector collects environmental data used for DER schedule forecast. ADATopologyUpdate changes connectivity in AdvancedDistributionAutomation database based on changes detected in real-time DMS and EnergyManagement SCADA. Fault-locating provides distances to fault location, which are used by operator or FLIR, along with other relevant data, to guide activities of field crews FLIR Steps Normal Sequence Describe the normal sequence of events, focusing on steps that identify new types of information or new information exchanges or new interface issues to address. Should the sequence require detailed steps that are also used by other s, consider creating a new sub, then referring to that subroutine in this. Remember that the focus should be less on the algorithms of the applications and more on the interactions and information flows between entities, e.g. people, systems, applications, data bases, etc. There should be a direct link between the narrative and these steps. The numbering of the sequence steps conveys the order and concurrency and iteration of the steps occur. Using a Dewey Decimal scheme, each level of nested procedure call is separated by a dot.. Within a level, the sequence number comprises an optional letter and an integer number. The letter specifies a concurrent sequence within the next higher level; all letter sequences are concurrent with other letter sequences. The number specifies the sequencing of messages in a given letter sequence. The absence of a letter is treated as a default 'main sequence' in parallel with the lettered sequences. Sequence 1: Sequence 2: Do step 1 1.2A.1 - In parallel to activity 2 B do step 1 1.2A.2 - In parallel to activity 2 B do step 2 1.2B.1 - In parallel to activity 2 A do step 1 1.2B.2 - In parallel to activity 2 A do step Do step nested step nested step 3.2 Volume II D29-65 Final Release

Multi-feeder reconfiguration with ability to optimally select feeder(s) connectivity for a given objective VVC Steps Normal Sequence Describe the normal sequence of events, focusing on steps that identify new types of information or new information exchanges or new interface issues to address. Should the sequence require detailed steps that are also used by other s, consider creating a new sub, then referring to that subroutine in this. Remember that the focus should be less on the algorithms of the applications and more on the interactions and information flows between entities, e.g. people, systems, applications, data bases, etc. There should be a direct link between the narrative and these steps. The numbering of the sequence steps conveys the order and concurrency and iteration of the steps occur. Using a Dewey Decimal scheme, each level of nested procedure call is separated by a dot.. Within a level, the sequence number comprises an optional letter and an integer number. The letter specifies a concurrent sequence within the next higher level; all letter sequences are concurrent with other letter sequences. The number specifies the sequencing of messages in a given letter sequence. The absence of a letter is treated as a default 'main sequence' in parallel with the lettered sequences.
