Distributed Energy Resource Interconnection SCC 21 Coordination
Standards Development Activity Interconnection IEEE 1547A Amendment to Standard for Interconnecting Distributed Resources to the EPS Today, IEEE1547-2003 Restricts Voltage, Frequency Regulation or Power Factor Correction at the PCC Wording added to allow Voltage, Frequency Regulation (by injecting reactive Power) and Power Factor Correction in collaboration with EPS operator. Implementation may favor Special Purpose Utility Interactive Inverter systems. Targeting ballot draft in late 2013 Key: Current Situation Probable 2013 Activity
Standards Development Activity Interconnection P1547.8 Recommended Practice for Establishing Methods and Procedures that Provide Supplemental Support for Implementation Strategies for Expanded Use of IEEE Standard Group was formed mainly from IT/Communications professionals and Inverter manufacturers. More Clarity on Inverter-based applications and Extended use applications: High penetration of Renewables MicroGrid Transfer support (circuit reconfiguration) Black start Ancillary services Targeting ballot draft in late 2013 Key: Current Situation Probable 2013 Activity
Standards Development Activity Smart Grid Interoperability IEEE P2030.2 - Guide for the Interoperability of Energy Storage Systems First standard using the IEEE 2030 Smart Grid Interoperability model. I am Working Group Chair Writing Committees Engaged to produce a ballot draft by end of 2013. Implications for communications and SCADA requirements and increased market participation. Key: Current Situation Probable 2013 Activity
Standards Development Activity IEEE 2030-2011 - Guide for Smart Grid Interoperability More commonality and completeness in communications and information technology requirements Power Systems Logical representation of Electric Power System Communication Technology Networks available to move data Customer Distribution Network Common Domains Transmission Network Bulk Generation Utility Operations & Control Service Providers Markets Information Technology Data Characteristics and Data Flows 7
Standards Development Activity Special Cases UL Standards Technical Panel 1741 (Inverters and Converters) Type Testing Standard for Inverters and Converters Revision due in 2013 CRD to break UL1741 from IEEE1547 requirements. Applies to Large Inverter systems employing Special Purpose Utility Interactive Inverters UL Standards Technical Panel - UL 6171 Standard for Wind Turbine Converters and Interconnection Systems Equipment (Startup in late 2013) No standards exist today. Clarity on interconnection and load testing requirements. Key: Current Situation Probable 2013 Activity
FERC Interconnection Rules Interconnection FERC Proposed Reforms for Small Generator Interconnection [Docket No. RM13-2-000] 1. Allow customers to request a pre-application report to evaluate opportunity. No review exists today. 2. Revise 2 MW threshold for participation in the Fast Track Process (FTP) increased to a limit of 5 MW 3. Revise the customer options supplemental review for projects that fail FTP criteria. No feedback or follow-up allowed. 4. FERC s pro forma Small Generator Interconnection Procedures (SGIP) revised to allow customers an opportunity to provide written comments on the upgrades that are necessary for the interconnection (transmission provider has total say) Key: Current Situation Probable 2013 Activity
FERC Interconnection Rules Fast Track Eligibility Size Limit Increased: Fast Track Eligibility Regardless of Fast Track Eligibility on 600 Amp Line and 2.5 Miles from Substation Line Voltage Location < 5 kilovolt 1 MW 2 MW (kv) 5 kv and < 2 MW 3 MW 15 kv 15 kv and 3 MW 4 MW < 30 kv 30 kv 4 MW 5 MW 10 4/16/2013
FERC: Screening Questions (Sample) Must be on a portion of the Transmission Provider s Distribution System that is subject to the Tariff Type of Connection that will Pass: Distribution Line Three-phase, three wire Three-phase, four wire Type of Interconnection 3-phase or single phase, phaseto-phase Effectively-grounded 3 phase or Single-phase, line-to-neutral Aggregated generation on the circuit shall not exceed 15 % of the line section annual peak load 11 Generation on the distribution circuit, shall not contribute more than 10 % to the distribution circuit's maximum fault current 4/16/2013
FERC Interconnection Rules - Pre Application Report Transmission Provider is required to provide information regarding: Total capacity and available capacity of the facilities that serve the Point of Interconnection; Existing and queued generation at the facilities likely serving the Point of Interconnection; Voltage of the facilities that serve the Point of Interconnection; Circuit distance between the proposed Point of Interconnection and the substation likely to serve the Point of Interconnection (Substation); Number and rating of protective devices and number and type of voltage regulating devices between the proposed Point of Interconnection and the Substation; Number of phases available at the proposed Point of Interconnection; Limiting conductor ratings from the proposed Point of Interconnection to the Substation; Peak and minimum load data; and Existing or known constraints associated with the Point of Interconnection. 12 4/16/2013
FERC Interconnection Rules -Workshop FERC Workshop to be Held on March 27, 2013 https://www.ferc.gov/whats-new/registration/small-generator-03-27-13-form.asp Topics for Discussion at Workshop: How the Fast Track Process should be modified to protect system safety and reliability. The specific content of the screens proposed rules: Amount of minimum load data is appropriate to use in the minimum load screen (12 months proposed) Potential modifications to the screens Whether the fee for the supplemental review is appropriate. The content of the pre-application report. Whether storage devices could fall within the definition of Small Generating Facility The proposed rules related to disconnection during an over- or underfrequency event. 13 4/16/2013
Implication of these Developments Significant changes to interconnection rules Increased application for Inverter-Based interconnections Increased opportunity for distributed energy resources economic-driven generation installations 14 4/16/2013
