Research on energy storage depth planning of AC / DC distribution network based on toughness enhancement technology

Abstract

At present, due to the abnormal objective function setting result of AC / DC distribution network energy storage depth planning method, the operation cost of power supply network has been increased frequently. Therefore, the energy storage depth planning method of AC / DC distribution network based on toughness enhancement technology is designed. The minimum peak valley difference, maximum load rate and minimum load change are taken as the energy storage depth planning objectives of AC / DC distribution network. The economic mathematical model of distribution network planning is constructed by using toughness enhancement technology and objective function to complete the in-depth planning of distribution network. So far, the energy storage depth planning method of AC / DC distribution network based on toughness enhancement technology has been completed. Simulation experiment has been constructed. Through the comparison, it can be seen that this method has better effect than the original method, possessing stronger control ability for operation components.
