Optimal Allocation of Energy Storage Capacity in High Proportion Clean Energy Parks Considering Demand Response

In order to improve the level of clean energy consumption and the economy of energy storage allocation in parks, an optimal allocation method for energy storage capacity of high-proportion clean energy parks considering demand response is proposed. Firstly, the photovoltaic, wind turbine, and energy storage power models are established. Secondly, a demand response mechanism considering the participation of rigid, transferable and interruptible loads is designed to realize the transfer of loads under a certain time scale. Then, taking the lowest total net present cost of the system as the optimization goal, an energy storage economic allocation model is established with consideration of the constraints such as grid-connected power fluctuations and charge & discharge limits. Case study verifies the effectiveness of the proposed method, and the results show that compared to the traditional method, the proposed allocation method can effectively reduce the economic cost of the system and improve the level of clean energy consumption.
