This case study discusses the battery-based energy storage aggregation system developed as part of the Yokohama Smart Community Project. Dubbed battery SCADA, it has been used to explore how distributed battery-based energy storage systems can be virtually aggregated to provide ancillary services such as frequency regulation to the grid as well as peak-shifting for the end-consumer.
