摘要
无功分区节点错误规划会导致微电网实时功率异常增大,从而造成电能过量消耗的问题.为控制微电网实时功率水平,选定正确的无功分区节点,提出基于NSGA-II算法的微电网无功分区节点选择方法.利用NSGA-II算法分析微电网局限性,定义无功区域划分原则,完成微电网无功区域划分.求解微电网无功分区内的类间合并距离,通过修正无功功率的方式,选择必要的分区节点,完成微电网无功分区节点选择方法的设计.实验结果表明,所提方法可将微电网实时功率控制在4.0×109 kW之下,达不到微电网的额定功率水平,表示所选择无功分区节点不会造成微电网电能过量消耗的问题.
Abstract
Incorrect planning of reactive power partitioning nodes can lead to abnormal increase in real-time power of microgrids,resulting in excessive energy consumption.To control the real-time power level of microgrids and select the correct reactive power partitioning nodes,a method for selecting reactive power partitioning nodes in microgrids based on the NSGA-II algorithm is proposed.NSGA-II algorithm is used to analyze the limitations of microgrid,define the principle of reactive power area division,and complete the reactive power area division of microgrid.Solve the merging distance between classes within the reactive power partition of the microgrid,select necessary partition nodes by correcting the reactive power,and complete the design of the node selection method for the reactive power partition of the microgrid.The experimental results show that the proposed method can control the real-time power of the microgrid below 4.0×109 kW,which cannot reach the rated power level of the microgrid,indicating that the selected reactive power partition node will not cause the problem of excessive power consumption of the microgrid.
