Selection of reactive power partitioning nodes in microgrids based on NSGA-II algorithm
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.
