Feasibility studies of end-customer's local energy storage on balancing power market

The objective of the paper is to develop an algorithm to estimate the profitability of energy storage operation in the balancing power market. The main reasons for this study are the fast growth of the PV battery market in the residential sector in the coming years and, at the same time, challenges related to the integration of huge amounts of renewables into the grid. The paper focuses on a single residential customer's battery storage operation. It shows that using the storage for the local services such as peak shaving, maximization of self-consumption using PV modules and operation on the spot price arbitrage turns out to be too expensive because the storage is then underutilized. The results show that the operation of a battery unit in the balancing power market as part of a virtual power plant not only delivers high profits but also ensures the profitability of the battery operation also for the local primary applications.
