Power grid expansion planning method considering flexible adjustment capability of system

The invention relates to a power grid extension planning method considering the flexible adjustment capability of a system, and the method comprises the steps: building a function block power distribution network extension planning model containing a distributed power supply and an energy storage system through considering the utilization of demand side response and flexible resources of the energy storage system; the problem of limited operation is solved by using various active power distribution network management means in the scene that the output of the distributed power supply is seriously not matched with the load, and the acceptance capability of the power distribution network to the distributed power supply can be effectively improved. 本发明涉及一种计及系统灵活调节能力的电网扩展规划方法，考虑利用需求侧响应、储能系统灵活性资源，建立含分布式电源及储能系统的功能块配电网扩展规划模型，在分布式电源出力与负荷严重不匹配的场景中使用多种主动配电网管理手段解决运行受限问题，可有效提高配电网对分布式电源的接纳能力。
