Analysis of Battery Storage Usage of Heuristic Energy Flow Controllers

Abstract

Due to the increasing usage of renewable energy sources like photovoltaic (PV) systems in the private sector and their fluctuations in production, energy management systems (EMS) are becoming more and more important. As such system use the produced energy as efficiently as possible, they also have an influence on a battery storage which is often installed together with the PV system. Nowadays batteries are already durable and cost efficient, but the possible negative effects an EMS might have on its usage and lifetime still need to be taken into account and be aware of. This is why this work analyses the battery usage of heuristic energy management controllers in detail and compares them to two existing energy management systems. It is shown that the heuristic energy management controllers are able to reduce the number of used battery cycles and therefore also the charged and discharged energy remarkable compared to the rulebased self-consumption optimization and the linear MPC, which also leads to a prolongation of the battery lifetime.
