Evaluating Residential Battery Energy Storage Systems for Up and Down-Regulation

This study presents a method to consider residential Battery Energy Storage Systems (BESSs) for providing Ancillary Services (ASs). Residential prosumers with Renewable Energy Sources (RESs) can use BESS to increase the local self-consumption. To obtain additional benefits, BESSs can also be managed to provide ASs. This brings additional benefits to prosumers and provides additional flexibility to the Distribution Grid (DG). As individual participation in the electricity market is not economically feasible, prosumers should be aggregated and operated by a local aggregator. The aggregator intercommunicates with the System Operator (SO), analyses the possibility of auxiliary services provision, and can make an offer/bid to the Ancillary Service Market (ASM). Once the offer/bid is accepted, the aggregator can operate the BESSs of the prosumers accordingly. This study analyses the economic attractiveness of prosumers' participation in the up and down-regulation.
