Abstract

In order to enable the isolated microgrid to achieve a greater degree of matching between the source-side power and the load-side power, based on the flexibility theory, an optimal scheduling model considering the matching of the flexible supply and demand is proposed. With the goal of maximizing economic benefits and maximizing the degree of flexibility in matching between supply and demand, the multi-objective particle swarm optimization algorithm is used to obtain the Pareto solution set of the optimization problem, and a solution that is more in line with actual needs is selected. The simulation results show that the proposed optimal scheduling strategy can effectively improve the system’s ability to deal with the volatility and randomness of the output of renewable energy generator sets, and improve economic benefits.
