用户侧储能系统容量配置与运行策略研究OA

In order to improve the economic benefits of the user-side energy storage system under the time-of-use pricing,this paper proposes a two-stage optimization model for PV energy storage systems considering time-of-use pricing and demand management,and analyzes its economic efficiency over the entire life cycle.The upper-layer model considers the long-term historical data throughout the year and the economy over the entire life cycle to configure the energy storage capacity.The lower layer optimizes the operation strategy of the energy storage system in real time based on the load forecasting data to reduce the demand-based electricity consumption cost.Taking a manufacturing base in Hangzhou as an example,the energy storage capacity and operation strategy are determined through optimization.The results show that the optimized energy storage system significantly improves economic benefits,reduces the electricity purchase cost,and increases the proportion of photovoltaic power consumption at the same time.
