Economic and Technical Optimization Configuration Methods for Energy Storage on the New Energy Side

In recent years, the proportion of installed capacity of new energy generation has been increasing year by year. It is urgent to install energy storage system to reduce the impact of intermittency and volatility on the power system. To this end, an economic and technical optimization configuration method for energy storage on the new energy side is proposed. With the objective of reducing wind and photovoltaic (PV) output volatility and maximizing the comprehensive economic value of energy storage systems, a technical and economic optimization configuration model is constructed. The comprehensive value considers the internal and external values of energy storage. Taking a certain region as an example, the NSGA-II algorithm was used to obtain the energy storage configuration plan. It has shown that when the suppression rate of wind and PV output fluctuations is controlled within 30%, and the proportion of PV to wind installation is low, configuring a certain scale of energy storage can achieve significant effects in both technical and economic aspects.
