Active power distribution network elastic self-healing method considering dynamic micro-grid and controller

The invention discloses an active power distribution network elastic self-healing method considering a dynamic micro-grid and a controller, the effect of the dynamic micro-grid in active power distribution network fault self-healing is considered, and the method comprises the following steps: obtaining a topological structure, network parameters and distributed power supply parameters of an active power distribution network, and constructing an active power distribution network simulation model; building a reinforcement learning framework oriented to real-time management and control of the active power distribution network; based on a hierarchical reinforcement learning mechanism, modeling the power distribution network fault dynamic recovery strategy according to a hierarchical decision-making mechanism; modeling a layered target reward function, and generating a reward signal according to the operation state of the power distribution network; simultaneously training a high-level strategy and a low-level str
