Planning and Dispatching of Distributed Energy Storage Systems for the Urban Distribution Network Considering Source-Grid-Load-Storage

Under the goals of carbon peaking and carbon neutrality, the adoption of clean energy for power generation has become an essential choice for the power industry. The distribution system plays an essential role in clean energy consumption and user-side emission reduction, however, it also faces new challenges. Firstly, we propose a framework of energy storage systems on the urban distribution network side taking the coordinated operation of generation, grid, and load into account. Secondly, we establish a capacity optimization model for energy storage systems by considering the various costs of energy storage systems throughout their entire lifecycle. Furthermore, we establish an optimization dispatch model that incorporates the limitations of both energy storage systems and distribution network flow to minimize the overall operational expenses. Finally, a planning-operation double-layer optimization model is constructed, considering both the capacity optimization configuration and the optimization dispatch of the coordinated operation of generation, grid, and load, and the effectiveness of the proposed optimization configuration scheme is verified through case studies.
