Storage & Advanced Grid Discussion 9:00 am 09:30 am 10:05 am 10:30 am 10:45 am Welcome and Distributed Energy Resources - Grid Standards Around the World SIRFN Smart Grid Collaboration and Storage Tom Tansy, Chairman, SunSpec Alliance UL Standards Update: Advanced Inverter, Energy Storage and Cybersecurity Scott Jezwinski, Business Development Manager, UL LLC Test Automation of Advanced Grid Integration Case Study Bob Fox, Principal Engineer, SunSpec Alliance, U.S. Storage Device Standards - New SunSpec Storage Models & MESA Energy Storage Case Study Andrew Miller, Vice President, 1Energy Systems, U.S. Round Table Discussion from the Speakers
About SunSpec Alliance Trade alliance started in 2009 Mission to establish Information Standards for Distributed Energy 100+ global members, partners & research institutes
SunSpec Alliance Vision Open Architecture
State of the Distributed Energy Market Large and growing PV: 250+ GW in 2015 Battery Storage: 2+ GW Global Europe U.S. Asia Becoming smarter Interactive Communicative Integrated
U.S. Distribution Grid in 2016 29.3 GW in total DG capacity 1 million installations! Will double by 2017 Pockets of high penetration CA: 12 GW by 2020 HI: 50% of circuits at 100% of daytime load today MA, NY, NJ, NC next up Advanced inverter functions mandated CA Rule 21, HI Rule 14H in place Revised national standard (IEEE 1547) coming Source: GTM 6
Grid Performance Requirements Voltage & frequency control protection How to tell when/where there is a problem (e.g., fault) Ensure safety, prevent damage to equipment, avoid cascading Voltage magnitude Frequency Power Quality (e.g., distortion) System stability How voltage and frequency recover from a disturbance Continuity of service Benchmark: 1-day cumulative outage per customer in a 10- year span (99.97% reliable) 7
