Integrated energy system economic dispatch optimization method, system and device, and storage medium

Abstract

The invention provides an integrated energy system economic dispatch optimization method, system and device, and a storage medium. The method comprises the steps of obtaining original data related to a day-ahead economic dispatch scene of an integrated energy system; according to the original data, establishing an integrated energy system day-ahead economic dispatch optimization objective function which takes integrated energy system economic operation minimization including energy purchase cost and charging and discharging depreciation cost of electric energy storage as an objective, establishing an integrated energy system day-ahead economic dispatching constraint condition covering power balance, external energy supply and equipment operation of the integrated energy system; and based on the day-ahead economic dispatching optimization objective function of the integrated energy system and the day-ahead economic dispatching constraint conditions of the integrated energy system, solving an optimal day-ahead economic dispatching scheme of the integrated energy system by adopting a multi-group particle swarm algorithm. According to the method, energy supply is optimized, transverse cooperative complementation and longitudinal gradient utilization among multiple energies are achieved, distributed renewable energy consumption is promoted, and the energy utilization rate is increased.
