HAA Tools Roadmap October 26, 2016 PHAAUG Face to Face Meeting April Freeman Reliability Services Engineer
Situational Awareness View 2 The proposal for Situational Awareness View is for filtering and grouping contingencies o No notes or attachments are supported igrid displays have an underlying XML file that feeds the display o Exploring the option of updating the XML file based on the subscriptions that you maintain as part of RTCA Alarming o Your subscriptions would feed your own custom RTCA igrid display
Automating Studies Peak is planning to work with one of our customers to test the ability for you to automate topology changes due to outages in STNET studies Peak will provide you with the file format required to input data, you will be responsible for creating outage files in correct format. 3
Automation Considerations Updates to the file management tool Peak needs to figure out: o Shared Folder o Load data may need to include data for all entities so may not be available for automatic input in first trial 4
What else should we focus on? Voltage Stability Analysis SMTNET Dynamic Limit Assessments 5
Voltage Stability Analysis 6 Voltage Stability Analysis in STNET allows the user o To stress any case to see where the limit of the system is by applying a custom scenario to predefined interfaces Network copy of current case Study case with contingencies applied Planning case o Get a precise idea of how much load can be added to the system before there is an invalid solution
VSA Custom Scenarios 7 Define Source Area(s) o Define specific units to include/exclude Define Sink Area (s) o Define specific loads to include/exclude Define an Interface o Define all lines that you want to monitor between source/sink Define maximum increase & iteration step size (MW) for stressing system
VSA Considerations Peak to define custom scenarios for you Need to figure out o If interfaces can be created for HAA only There is the ability to create interfaces via the UI, but it will probably get deleted after each new case is loaded into a clone o If custom display(s) needs to be created Can HAA users see others scenarios 8
SMTNET Multiple Timepoint Network Study Performs look ahead study for each timepoint For each timepoint, it reads scheduled outages, generation profile, load forecast, and interchange schedule data. Max No. of timepoints: 12 (configurable) 9
Overview 1. Create multiple timepoints Analyst Trigger Study Summary 6. Store violation For every timepoint 2. Read databases smtnet netmom ctgs rasmom 5. Run Contingency Analysis STCA 3. Update schedules and flat file data 4. Run Power Flow NPF netmom ctgs rasmom 10
User Interface 11

Performing Multi Timepoint Study Run Solution Sequence with Contingency Analysis 17
Results Run Solution Sequence with Contingency Analysis 18
Results 19
Additional features Enable/Disable contingency groups Enable/Disable certain RAS schemes Each timepoint can be linked to a different savecase Various savecase creation options 20
SMTNET Considerations Peak is not currently performing multi timepoint studies o Process driven, not application driven Licensing with GE 21
