Abstract

With the rapid development of distributed power generation with renewable energy as the core, the proportion of energy storage stations connected to the grid is constantly increasing. The access of a large number of energy storage stations will inevitably affect the voltage level and line flow level of the distribution network. Therefore, by reasonably optimizing the access location and capacity of the energy storage station to ensure that its impact on the distribution network is optimal. On this basis, this article uses a multiobjective optimization method to define the minimum voltage deviation, the optimal transmission line margin, and the minimum network loss as the optimization goals. And the firework algorithm is used to solve the problem, and the best access location and access capacity of the energy storage station are obtained. Finally, the IEEE35 node case is used in MATLAB to carry out the simulation calculation to prove the validity of the conclusion. Therefore, the planning scheme of energy storage station proposed in this article has effective theoretical significance and practical value.

基于电网最优影响的并网储能电站布局研究

随着以可再生能源为核心的分布式发电的快速发展，储能电站并网比例不断提高。大量储能站的接入必然会影响配电网的电压水平和线流水平。因此，通过合理优化储能站的接入位置和容量，保证其对配电网的影响是最优的。在此基础上，本文采用多目标优化方法，确定电压偏差最小、输电线路裕度最优、网损最小为优化目标。并采用烟花算法对该问题进行求解，得到了储能站的最佳接入位置和接入容量。最后，以IEEE35节点为例，在MATLAB中进行仿真计算，验证结论的有效性。因此，本文提出的储能站规划方案具有有效的理论意义和实用价值。
