Research on Cost-Benefit Analysis and Arbitrage Strategy of Energy Storage for Industrial Users

The reduction of energy storage cost and the improvement of time of ues(TOU) mechanism jointly promote the development of energy storage on user side. The energy storage on user side can reduce the power consumption cost and even realize arbitrage through peak shaving and valley filling. This paper evaluates the economy of energy storage on user side by calculating the net annual value(NAV) while considering the benefits of saving electricity, reducing transformer capacity, residual value recovery, energy storage system cost, civil engineering and installation cost, operation and maintenance cost and other factors. In this paper, the economy of adding energy storage to four typical industrial loads is calculated respectively, and the charging and discharging scheme of energy storage device is given.
