Optimization Method of Energy Storage Configuration of New Energy Access to Micro-Grid

针对传统方法无法达到预期效果的问题,本文提出新能源接入微网储能配置优化方法。首先建立目标函数,根据储能系统充放电功率和荷电状态设置约束,建立储能优化配置模型,然后利用麻雀搜索算法求解完成新能源接入微网储能配置优化。实验证明,应用本文方法后,微网年综合成本降低,且等效负荷标准差不超过5 kW。

In response to the problem that traditional methods cannot achieve the expected results,this paper proposes an optimization method for the configuration of new energy access microgrid energy storage.Firstly,establish an objective function,set constraints based on the charging and discharging power and state of charge of the energy storage system,establish an energy storage optimization configuration model,and then use the sparrow search algorithm to solve and complete the optimization of new energy access microgrid energy storage configuration.Experimental results have shown that after applying the method proposed in this paper,the annual comprehensive cost of microgrids is reduced,and the standard deviation of equivalent loads does not exceed 5 kW.
