Applications of DER Advanced Functions and Settings Devin Van Zandt, EPRI August 28, 2019 ITWG Meeting w w w . e p r i . c o 2019 Electric Power Research Institute, Inc. All rights reserved. m NYSERDA PON 3770 - Smart Inverter Settings Guidance for High Performing Smart Grid Applications Research Questions What do IEEE 1547-2018 inverter settings mean to me? How effective are inverter functions for specific applications? What are the key considerations related to choosing functions and settings? What is the method to choose the best settings and functions for my applications? Scope/Approach Examine past simulation work related to inverter settings Technical considerations for selection of functions and settings Identify key factors and Settings Performance Produce a methodology for efficiently choosing the best
settings Expected Outcome Application guidelines and a method/tool for determining settings for a variety of applications Improved understanding of impacts to maximize technical, policy, and business goals Generalized Inverter Function and Settings Guidance 2 ww w.epri.co m 2019 Electric Power Research Institute, Inc.

39 utilities participated in online survey Performed interviews for Avangrid, Orange & Rockland, Con Edison Central Hudson and National Grid provided survey results Initial findings 6 Understand current usage of advanced DER functions What is being considered in the future? What are primary objectives for usage? Voltage considerations are generally most important 70% dont have a policy, but plan to have one in the future Less than 45% of utilities have evaluated advanced functions
