Problems solved by technology

[0004] Considering that there are few studies on the coordinated operation of the agricultural park-type integrated energy system and the rural distribution network for the comprehensive utilization of wind-light-biomass energy, it is impossible to effectively realize the coordinated economic security of the agricultural park-type integrated energy system and the rural distribution network. Therefore, it is necessary to conduct an in-depth exploration of the coordinated operation of the distribution network and the park-type integrated energy system
