摘要(Abstract)：

高压配电网是连接输电网和中压配电网的重要环节,其规划结果将影响城市供配电系统整体的经济性和可靠性;然而目前高压配电网规划与输电网规划之间缺乏协调,其规划模型和方法不够精细。针对该问题提出了改进的输电网与高压配电网协调规划的流程,建立了高压配电网优化规划的2阶段模型,综合考虑了220 kV变电站容量规划、110 kV高压配电网线路规划和负荷优化分区,可实现220 kV变电站、110 kV高压配电网线路扩建和网络损耗总费用的最小化。应用改进遗传算法求解该模型,在始终保持遗传算法中解的可行性前提下进行大规模寻优,提升了算法的全局搜索性能和收敛速度。针对某地区实际高压配电网络的规划结果验证了模型的合理性和算法的实用性。
