Policy Requirements and Economic Affordability of Energy Storage for New Energy

The allocation of energy storage has become a necessary condition for the development and construction of new energy power stations in some provinces. The deployment of energy storage will increase the cost of new energy construction. Different regions in China have different levels of tolerance for the deployment of energy storage capacity. The deployment of energy storage will change the development layout of new energy. This paper expounds the policy requirements for the allocation of energy storage, and proposes two economic calculation models for energy storage allocation based on the levelized cost of electricity and the on-grid electricity price in the operating area. The energy storage capacity of the centralized photovoltaic power generation configuration is calculated. The results show that the wind power capacity is better than that of photovoltaics. Generally speaking, the North China and Northeast China regions have endurance capacities, while the Northwest region has no capacity.
