Abstract
To explore the influence of grid connected electric vehicle on microgrid and its collaborative control under the background of new energy power generation, in this study, the constraints of electric vehicle are established from two aspects of electric vehicle travel characteristics and battery charging and discharging characteristics. In view of the variety of controllable resources in microgrid, multi-agent microgrid coordination control architecture is used to control the multi-layer coordination of microgrid, and simulation is built to analyze four different scenes. The results show that in the microgrid load, it is found that the valley peak difference is the smallest when both the electric vehicle and the conventional load participate in the demand response (scene 4). In the change of SOC and charge discharge power of battery energy storage system, it is found that four scenes make the energy storage function of “low storage and high generation” play an effective role. In the economic and environmental benefits of microgrid daily operation, it is found that the daily operation cost and environmental benefits of scene 4 are significantly lower than that of scene 1. Therefore, in this study, the coordinated optimization method of integrating electric vehicle into microgrid based on multi-agent microgrid can effectively solve the coordinated optimization of multi controllable resources of microgrid, and provide experimental basis for the subsequent development and optimization of microgrid.
