Optimal coordinated operation for microgrid with hybrid energy storage and diesel generator

Compared with the conventional cooperation model of single energy storage and diesel generator, a new coordinated operation model of hybrid energy storage and diesel generator is proposed in this paper, considered about the running characteristics of hybrid energy storage and diesel generator. According to the daily load curve and wind-solar output curve, the strategy of coordinated operation is determined based on the index analysis in sliding time window which is separated by enumeration method. In view of the wind-solar-diesel-hybrid storage DC microgrid, this paper set economic efficiency as the optimization target with time-dependent electricity price, using enumeration to divide multiple time scales and choose coordinated operation model, then employed adaptive genetic algorithm(AGA) to optimize the power resources.
