摘　　要：针对目前对输配电网协调性考虑不足的问题,考虑机组间负荷优化分配因素,引入耗量成本,构建了包含输配电网协调性指标的电网评价指标体系。结合电网经济性指标和可靠性指标,通过优化算法选出综合性能最优的输配电网规划方案。在解决遗传算法"早熟"、易陷于局部最优等问题的基础上,提出了一种优化算法并将其应用于考虑输配网协调性的电网规划问题中。仿真计算结果表明,所提出的方法是可行、高效的。There is currently insufficient consideration of the coordination of the power transmission and distribution network.In considering the optimization of load distribution among units and introducing consumption costs,a grid evaluation index system including the coordination index of the power transmission and distribution network is constructed.Combining the economic and reliability indicators of the power grid,the power transmission and distribution network planning scheme with the best comprehensive performance is selected through optimization algorithms.To solve the problems of a genetic algorithm being"premature"and easily falling into a local optimum,an optimization algorithm is proposed and applied to the grid planning problem considering the coordination of transmission and distribution network.The simulation results show that the proposed method is feasible and efficient.
