NERC DERTF Update
This document provides insights into the NERC DERTF update focusing on Distributed Energy Resources (DERs). It covers the purpose, scope, current activities, and sub-group activities related to DERs including definitions, connections, modeling, and operating characteristics. The update includes information on impacts, planning, modeling, standards review, and reliability gaps identification. The activities involve research, meetings, calls, and workshops to enhance understanding and address the challenges associated with DERs in the energy sector.

NERC DERTF Update Jagan Mandavilli Senior Reliability Engineer Texas RE ERERERCOT WMS June 3, 2015
Purpose Based on the recommendations from ERSTF that concluded at the end of 2015, a new task force was formed as part of the ERSWG. The main activity of this task force is to research in to all aspects of DERs and produce a white paper by the end of 2016. ERCOT ETWG, June 2016 2
SCOPE DERTF scope included activities related to the following: Impacts on Operations Impacts on Planning Modeling of DERs Provide clarification regarding BTMG,DG and other related terms and provide distinctions between these categories Review the current NERC standards and identify standards that are related to the DERs Review and identify reliability gaps if any of the above standards and document the same ERCOT ETWG, June 2016 3
Current Activities Formation of sub groups to research in to individual areas Face to Face meetings Conference calls Workshops ERCOT ETWG, June 2016 4
Sub group Activities What are Distributed Energy Resources? Definitions Behind the Meter Generation (BTMG) Distributed Generation (DG) Demand Response Typical resources? Solar, small hydro, wind, what? ERCOT ETWG, June 2016 5
Sub group Activities How are Distributed Energy Resources connected? Low voltage BTMG NEC code and utility requirements Distributed Generation NESC and utility requirements Metering what data goes back to BA or utility? Real-time, hourly, monthly read? ERCOT ETWG, June 2016 6
Sub group Activities How are Distributed Energy Resources modeled? Distribution load is netted at source bus on present models Is it being modeled discretely anywhere? When does it become significant? NERC Load Modeling Task Force EPRI and WECC Guideline (PVD1 model) ERCOT ETWG, June 2016 7
Sub group Activities What are Distributed Energy Resources operating characteristics? IEEE 1547 Requirements (Now and Future) Frequency and voltage ride through Active fault source? Can it run independently of utility connection? Governor action FERC Notice of Inquiry on Primary Frequency Response FERC NOPR Voltage Support and Control ERCOT ETWG, June 2016 8
Sub group Activities What effects to Distributed Energy Resources have on the Bulk Electric System (BES)? Planning What is the net load? What is the peak load to serve? Operations Negative distribution load? Flow up the transformer? Fault source? Balancing Authority Load (Net load, Load Forecast, Reserve requirements?) ERCOT ETWG, June 2016 9
Sub group Activities Applicable NERC Reliability Standards MOD-010-0 MOD-012-0 Dynamics Data for Modeling and Simulation MOD-016-1.1 Documentation of Data Reporting Requirements MOD-017-0.1 Aggregated Actual and Forecast Demands and Net Energy for Load MOD-019-0.1 Reporting of Interruptible Demands and Direct Control Load Management MOD-020-0 Providing Interruptible Demands and Direct Load Control Management Data MOD-021-1 Documentation of the Accounting Methodology for the Effects of Demand- Side Management in Demand and Energy Forecasts MOD-031 is pending MOD-032 replaces MOD-010 MOD-033 replaces MOD-012 PRC-006 UFLS PRC-0?? UVLS schemes PRC-019 PRC-024-2 (pending) Generator Voltage and Frequency Coordination ERCOT ETWG, June 2016 10
Sub group Activities Recommendations Connection requirements Modeling Performance requirements? Accounting Load/Gen? Modifications to any NERC Standards? Load, Forecast, Reserve requirements? ERCOT ETWG, June 2016 11
Upcoming workshop Announcement Save the Date: Distributed Energy Resources Workshop Planned for August Time and Date: August 2, 2016 | 1:00 5:00 p.m. Eastern August 3, 2016 | 8 a.m. noon Eastern ATLANTA The North American Electric Reliability Corporation will host its Distributed Energy Resources workshop on August 2-3 in Atlanta, Georgia. The conference Maintaining the Reliability of the Bulk Power System with the Integration of Large Amounts of Distributed Energy Resources will focus on challenges and opportunities in bulk power system planning and operations associated with larger-scale integration of distributed generation. The workshop will serve as the foundation for technical and stakeholder i nput for NERC s Distributed Energy Resource Task Force, which will use the input to develop its final report on reliability considerations and future efforts. The workshop will be designed to create general awareness of DERs, including definitions, operating characteristics, the need for observability and control, and appropriate load and generation modeling to evaluate potential impacts to BPS reliability. It will also examine the operation of DERs during disturbances and effects of variability and ramping on real time operations. This workshop will be a collaborative opportunity to share information for effectively integrating distributed energy resources on the grid, while still maintaining reliability. As the electric reliability organization, NERC is committed to continuous learning and improvement of bulk power system reliability. More details on the conference will be provided in the coming weeks.
