Optimized configuration method of distributed energy storage for improving renewable energy accomodation in distribution network

With the increasing proportion of new energy in distribution power grid,the phenomenon of abandoning wind and light in off-peak load of distribution power grid becomes more and more serious.In order to improve the proportion of new energy consumption in distribution power grid and improve the operating income of distributed energy storage system,firstly the demand for the application of distributed energy storage system in distribution power grid is analyzed,and the rationality of using distributed energy storage system to improve the proportion of new energy consumption is made clear.Then,a distributed energy storage system optimal allocation method is constructed,which takes into account the arbitrage benefits and operation costs of energy storage system,and studies the optimal allocation of distributed energy storage system with the goal of optimizing the net income of energy storage system daily operation.Finally,the effectiveness of the proposed method is verified by the IEEE-33 node example system.The results show that the proposed energy storage system configuration method not only improves the proportion of new energy consumption in the distribution power prid,but also improves the safety and stability of the distribution power grid operation.
