摘要：
Energy storage system has played a great role in smoothing intermittent energy power fluctuations, improving voltage quality and providing flexible power regulation. Whether the distribution network can realize the complete consumption of intermittent renewable energy depends to a large extent on whether the energy storage system configuration of the active distribution network is reasonable. This paper proposes a distributed energy storage planning method considering the correlation and uncertainty of new energy output. Firstly, based on Cholesky decomposition, the sampling of new energy and load satisfying corresponding distribution is obtained simultaneously. Then, the distributed energy storage planning model considering the uncertainty of new energy and load is established. Secondly, making reasonable second-order cone relaxation for the energy storage planning model. Finally, the improved Portugal 54 node distribution system is used for simulation. The results show that new energy consumption capacity and the economy of the distribution network operation can be effectively improved by taking into account the energy storage access.
