UseCase Stack for Consideration Distributed Power Balancing (concept paper provided by Bruce McMillin) Frequency Control during island (based on EPRI Usecase) Limit maximum real power output at the PCC to a preset value (IEC TC8 WG6 DCT 4 Version 9) Provide dynamic reactive power injection through autonomous responses to local voltage measurements (IEC TC8 WG6 DCT 4 Version 9) Security: Mitigation During a Failure or Attack ( Resilience and Security for Power Systems with Distributed Energy Resources (DER) - Frances Cleveland)

Thoughts Imagine a Meter that provides four types of data to different actors in the system sub second data for local distributed apps (stability) sub second data for local distributed (optimization / forecasting) minute to monthly revenue for billing systems in the back office sub second data to support future transactive energy apps (so that all meters of a technical type from multiple vendors and multiple application vendors can play together)

F4:Unintentional Islanding These selections are based on the EPRI Microgrid Usecases One idea to test out latency is during an unplanned islanding event. If we are assume that ESS is in a smoothing operation and can ramp at 50ms based on lithium ion chemistry, what can we do to drop non-critical loads fast enough to maintain the stability of the island over different communication mediums Key requirement demonstrated - Low latency

F1 is Frequency Control These selections are based on the EPRI Microgrid Usecases Frequency Control in Island mode would probably be the most interesting. Ability to control the ESS KW output for frequency stabilization during load transition. Key requirement demonstrated - Low latency

Other Thoughts on Usecases A usecase that allows us to use data from a field devices for multiple applications that is typically siloed or limited via communications. For example metering devices can support visibility of the system and have the potential to use this data in multiple types of applications. A usecase that looks at adding new devices on to the network and how that process would work. For example, assume a microgrid, if we have new metering devices or a new generation asset what would be the right architecture design to drive towards a plug n play environment where distributed application don’t need to be reconfigured manually and the domain functions still work as prescribed.
