A multi-objective based capacity optimization design of standalone microgrid

In this paper, a multi-objective optimal configuration model of distributed generator capacity aimed at solar power, hydropower, diesel power and battery based microgrids is proposed, the model takes economy, environmental benefit and power supply reliability into consideration at the same time. Under the established control strategy, the adaptive weight particle swarm optimization algorithm is used to solve the model in order to obtain the capacity of the distributed generators in the microgrid. In example analysis part, an example of a western area of China is given to design the distributed generator capacity of the microgrid. The analysis of the results shows that the multi-objective optimization can achieve the best balance of economy, environmental benefit and power supply reliability, the analysis of the results also verifies the rationality and superiority of the proposed model and scheme.
