Coordinated operation of multi-energy microgrid with flexible load

Aiming at the economy of microgrid operation and the uncertainty of renewable energy, a coordinated operation schedule of a multienergy microgrid based on a flexible load is proposed in this paper. Considering the difference in price and demand characteristics of multienergy, a multienergy interaction model based on a demand side response is established in day-ahead scheduling. In the intraday rolling optimization phase, according to the state of charge of battery and the demand of load, different battery function models are established at different time intervals, cooperating with the flexible load to obtain the optimal value of each unit's output. The main purpose of day-ahead scheduling and intraday scheduling is to achieve economic optimal scheduling and real-time scheduling is to guarantee the stability of the system. Finally, the simulation results verify the effectiveness of the proposed strategy. The proposed coordinated operation schedule of the multienergy microgrid achieves an integrated optimization for multienergy-type supply.
