Preliminary research on the power supply of a real industrial load through load-leveling operation strategy of energy storage system

The use of Battery Energy Storage System (BESS), to power electrical loads connected to the distribution grid, can be a way to promote the integration of renewable energy into the network. This paper studies the techno-economic advantages of power supplying a real industrial load through a load-leveling strategy using a BESS. Two main case study scenarios are considered, obtained by varying the power consumption of the auxiliary systems. The results show that in practice the two scenarios are technically feasible. On the distribution network side, the proposed solution is particularly advantageous, introducing a load-leveling which is effective in reducing the absorption peaks by the user load. On the customer side, it does not offer a great economic advantage. In the best case, the return on investment, for the realization of the BESS, is guaranteed no earlier than 10 years.
