The integration of distributed battery energy storage systems has started to increase in power systems recently, as they can provide multiple services to the system operator, i.e. frequency regulation, system peak shaving, backup power etc. Additionally, batteries can be installed even in facilities where the installation of renewable energy sources are impossible, such as apartments within urban areas. Consequently, an aggregator could deploy distributed battery systems to households under his portfolio, utilising them to capitalize on Demand Response services while sharing benefits of electricity cost reduction with them. To enable that, this paper provides an integrated solution for monitoring, scheduling, and controlling a residential battery energy storage system. The proposed system has been realised in the context of inteGRIDy project to a pilot site that consist of 4 different dwellings that are located in Northern Greece. The analysis of the pilot results revealed that battery systems could exploit the variation in electricity price in order to succeed some profit alongside with the provided energy services.
