Description

technical field [0001] The present invention relates to the field of electric power, and more specifically, to a user-side energy storage capacity configuration method. Background technique [0002] The value of distributed energy storage on the user side lies in: 1. Utilize the difference in peak and valley electricity prices to reduce electricity bills by cutting peaks and filling valleys. 2. Through energy storage power compensation, capacity expansion investment is delayed and basic capacity costs are reduced. 3. Improve the reliability of power supply for users and reduce the loss of power cut and load shedding. [0003] For energy storage system configuration, there are many methods in the existing literature, including bee colony optimization algorithm, particle swarm algorithm, etc. Research institutions and universities at home and abroad have also conducted in-depth research on energy storage efficient configuration and done a lot of research work. However, most ...
