Problems solved by technology
In the case of lightning strike probability, there are still few technologies on how to adjust other schedulable energy sources for power support and transfer. The main reason is that other schedulable energy sources output at a constant power, and the adjustment method cannot dynamically update the output of other power sources according to the size of the lightning strike probability. Conducive to the economical operation of the system

A power control method for energy storage systems based on lightning strike probability. In the case of known lightning strike probability, in order to reduce the possible power loss of the system due to lightning strike, it is necessary to adjust other power sources to transfer the power flow, and then reduce the system when a lightning strike accident occurs. Loss. Energy storage, as a dispatchable power source, is a suitable power source for power flow transfer in lightning weather. The present invention compares the possible loss functions before and after energy storage adjustment, and obtains the loss difference function before and after. In the case of the smallest loss, the storage system is established. The relational expression between the output power of the energy storage system and the lightning strike probability is obtained, and then the output power of the energy storage system is controlled according to the lightning strike probability. The invention mainly has the following advantages: when the probability of lightning strike exists, the energy storage is dispatched to transfer the power flow, which can obviously reduce the loss caused by lightning.
Description
technical field [0001] The invention belongs to the technical field of dynamic lightning protection of electric power systems, and in particular relates to a power regulation method of an energy storage system based on lightning strike probability. Background technique [0002] At present, in the field of lightning protection of power systems, passive lightning protection measures such as installation of lightning rods and lightning conductors are mainly used. In order to further improve the system's ability to deal with lightning strikes, dynamic lightning protection related technologies have developed rapidly. In the case of lightning strike probability, there are still few technologies on how to adjust other schedulable energy sources for power support and transfer. The main reason is that other schedulable energy sources output at a constant power, and the adjustment method cannot dynamically update the output of other power sources according to the size of the lightning...
