Energy Community Resilience: A Multi-Objective Approach with Shared Battery Storage Systems

The introduction of shared battery storage in the energy community (EC) grid provides a unique solution to grid congestion issues. This paper presents an energy management strategy for ECs, leveraging shared communal battery storage (CBS) integrated with community resources to optimize energy distribution. The proposed hierarchical optimization framework is used to minimize costs and CO2 emissions while maximizing self-consumption, using CBS as a modular Virtual Battery Storage (VBS) adapted to community needs. Each VBS module within the CBS is used to optimize different objective functions in the energy management framework. This study demonstrates how the VBS concept can be incorporated into community energy systems for sustainable management and grid stability. The proposed approach is tested on the Aardehuizen community model based on a real EC located in Olst, the Netherlands.
