Abstract：The problem of the clean energy shortage in western rural communities can be solved using photovoltaic and energy-storage microgrid system, which is composed of photovoltaic energy storage and electric heating. To improve the energy control effect and engineering practical performance of the photovoltaic and energy-storage microgrid system, a multi-objective function is constructed in this paper, the considered variables include power cost, energy storage system SOC, heating comfort, etc. And then a multi-objective coordinated control strategy is proposed. In order to simply the solution process of objective function, derivation and monotonic analysis are adopted. In order to reduce the computation of the system, a new bandwidth energy control mode was proposed based on insulation performance of residential, which can reduce the unit control frequency and improve the algorithm engineering application value. Finally, the simulation platform is established by Matlab/Simulink, the performance of photovoltaic and energy-storage microgrid system utilizing traditional EMS energy control strategy and multi-objective coordinated control strategy are analyzed based on actual data of a demonstration photovoltaic and energy-storage microgrid system in western Qinghai Province, and the effectiveness and superiority of the proposed control strategy are verified.
