A response system and method for an integrated wind-solar-storage electric vehicle charging station during a thunderstorm are provided. Thunderstorm information of a region in which an integrated wind-solar-storage electric vehicle charging station and its power supply line are located is analyzed, and a tripping possibility of the power supply line of the integrated wind-solar-storage electric vehicle charging station is determined. Important electrical loads of the charging station and its power supply line are classified and counted. A demand response capability of the charging station is calculated, and a corresponding quantity of important loads are matched. When the power supply line trips, a location and an isolation status of a line fault point and power transmission waiting duration are determined, and the matched important load is adjusted accordingly. The charging station is enabled to participate in a demand response in the event of a thunderstorm and line tripping.

A lightning strike probability-based coordinated power control method for an energy storage system and a load adjusts output power of an energy storage system and a regulatable load based on a real-time predicted lightning strike probability. This reduces a correlation between a power grid in a lightning region and an external power grid, minimizes impact of a lightning strike if any on the external power grid, and decreases an economic loss due to the lightning strike in the lightning region. The present disclosure establishes a relationship between the output power of the energy storage system, the regulated power of the regulatable load, and a lightning strike probability in a same region, and then regulates the power of the energy storage system and the regulatable load in real time based on the lightning strike probability.
