摘要
新能源储能系统的分散负荷难以调度,导致整体协调效果较差,为促进新能源并网消纳,构建了改进NSGA-Ⅱ算法的新能源储能系统协调优化模型。设计新能源储能系统拓扑结构,使用NSGA-II算法定义协调目标拥挤度为储能动态调节参数。以新能源储能削减计划偏差最小为目标函数进行参数寻优,并确定转移容量指标和负荷平衡指标。在NSGA-II算法中引入收缩扩张系数,保证分散负荷资源搜索多样性,采用改进NSGA-II算法,由此构建协调优化模型。实验结果表明,该模型协调优化后光伏储能功率为43 MW,风电储能功率为65 MW,储热储能功率为16 MW,有效促进了新能源并网消纳。
The new energy storage system is difficult to dispatch due to decentralized load,resulting in poor overall coordination effect.To promote the grid connection and consumption of new energy,a new energy storage system coordination optimization model with improved NSGA-Ⅱ algorithm is constructed.The topology of new energy storage system is designed,and the coordination target congestion is defined as the dynamic regulation parameter of energy storage using NSGA-Ⅱ algorithm.The minimum deviation of new energy storage reduction plan is taken as the objective function for parameter optimization,and the transfer capacity index and load balance index are determined.The contraction expansion coefficient is introduced into NSGA-Ⅱ algorithm to ensure the diversity of distributed load resource search and facilitate scheduling.The improved NSGA-Ⅱ algorithm is adopted to build a coordination optimization model.The experimental results show that the photovoltaic energy storage power is 43 MW,the wind power energy storage power is 65 MW,and the thermal energy storage power is 16 MW after the coordinated optimization of the model,which effectively promotes the grid connected consumption of new energy.
