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.
