Research on the Application and Optimization of Load-Side Energy Storage in Distribution Networks

The application of load-side energy storage in distribution networks is becoming increasingly widespread, and its impact on voltage quality cannot be ignored. This paper considers a complex distribution network system composed of user loads, distributed generation, and reactive power compensation devices, studying the optimization effect of energy storage collaboration on the voltage quality of the distribution network. Through the construction of a complex distribution network model, the impact of energy storage integration into the distribution network is quantified. An improved multi-objective cone model is used to achieve collaborative voltage control of energy storage. Simulation analyses are conducted in the PG&E 69-node system, leading to the conclusion that load-side energy storage collaboration can effectively improve the voltage quality of the distribution network.
