Abstract This paper takes the light storage and charging integrated microgrid system as the research object, aiming to explore how to maximize the economy and stability of the system. This paper firstly analyzes the working characteristics of the light, storage and charging integrated microgrid system, analyzes the operating characteristics of photovoltaic, energy storage and electric vehicle in the microgrid and establishes a reasonable mathematical model, based on which this paper carries out a multi-objective optimization operation research on the light, storage and charging integrated system. This paper proposes an optimal operation strategy considering load peak and valley transfer, and on this basis, establishes an optimization model with the objectives of minimizing the load peak and valley difference in the system and minimizing the operation economic cost. The example shows that the peak-to-valley difference is reduced to 2.394 under the optimization model of this paper, which proves the effectiveness of this paper’s method in the integrated system of optical storage and charging, which can effectively reduce the peak-to-valley difference of the loads while guaranteeing the operation economy. The method of this paper can not only meet the user’s power quality requirements, but also reduce the system operating costs, optimize the operation of the distribution network, which can provide a reference for the current investment in the construction of the integrated optical storage charging power plant.
