摘　　要：针对无功补偿装置不协调、有功损耗大等缺点,文章提出了面向最小母线电压偏差和最低有功损耗的多目标的无功协调控制策略。该策略将静止无功补偿器(SVC)作为主要的无功补偿设备,并充分考虑不同变电站之间的无功补偿的相互作用。该策略采用改进的遗传算法对无功补偿控制变量的最优组合进行搜索。仿真结果表明,所提出的无功补偿模型能够有效降低母线电压偏差和补偿装置的有功损耗,优化算法具有更好的收敛性能,验证了无功补偿模型和优化算法的可行性。A multi-objective reactive coordinated control strategy for minimum bus voltage deviation and minimum active loss is proposed in the paper aiming at the disadvantages such as uncoordinated reactive compensation devices and high active loss,etc.Static Var Compensator(SVC)is used as the main reactive power compensation equipment in the strategy,and the interaction of reactive power compensation between different substations is fully considered.An improved genetic algorithm is adopted in the strategy to search for the optimal combination of reactive compensation control variables.The simulation results show that the proposed reactive power compensation model can effectively reduce bus voltage deviation and active power loss of compensation device,the optimization algorithm has better convergence performance,and the feasibility of the reactive power compensation model and optimization algorithm is verified.
