Abstract：Smart grid technology has made rapid progress, and large-scale new energy integration into the power grid has become the core feature of power system transformation. The intermittency and fluctuation of new energy output have posed great challenges in grid voltage stability, frequency regulation and power balance. The existing coordinated control strategy of electricity and gas still has insufficient adaptability when dealing with the requirements of multi-source heterogeneous energy coupling and dynamic response. This research takes the electrical coordination control after the new energy is accessed as the starting point, proposes a collaborative control strategy of hierarchical and distributed architecture, optimizes the interaction mechanism of source network load storage links, and improves the regulation ability and robustness of the system under complex operating conditions. Research and analyze the key causes of new energy output prediction error, inverter control mode switching and power coupling among multiple feeders, build a two-level control model including regional autonomy layer and global coordination layer, and introduce a dynamic weight distribution mechanism to balance the priority levels of different control objectives.
