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.

Provided are a load transfer method and system in thunder and lightning weather. The method includes: detecting lightning and predicting a position and time of a lightning strike to obtain a lightning prediction result; determining a transmission line possibly struck by lightning in a power grid according to the lightning prediction result; determining a load transfer scheme; and before the lightning occurs, transferring at least part of loads on the transmission line possibly struck by lightning according to the load transfer scheme.

Method and system for transferring a load in a thunder and lightning weather

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.

A lightning prewarning-based method for active protection against a lightning strike on an important transmission channel includes collecting meteorological element data, and establishing a transmission line-specific lightning strike probability prewarning model; using a maximum probability of a lightning strike prewarning level as a lightning strike prewarning level; performing equivalence calculation on a large-scale regional power system, using a minimum sum of a power loss risk cost and a regulation cost as an optimized objective function, and establishing a power flow transfer optimization model; and comparing a sum of a regulation cost and load power loss risk cost caused after the tie line is disconnected if regulation is performed before a lightning strike, and a load power loss risk cost caused if regulation is not performed, and when the regulation cost is not greater than the load power loss risk cost, performing regulation before the lightning strike.

Disclosed are a dynamic lightning protection method and system. The method includes detecting lightning in real time and tracking a position of a thunderstorm; and performing dynamic lightning protection and control on an electrical grid according to an electrical grid control strategy before the thunderstorm reaches or affects the electrical grid. Further disclosed is a dynamic lightning protection system.
