Research and Analysis of Microgrid Control Strategy

The aim of this paper is to verify the feasibility and effectiveness of integrated control strategies for microgrids. To achieve this goal, we constructed a microgrid control model on a simulation platform and conducted in-depth simulation analyses of the characteristics of the microgrid in two key operating states. Firstly, we simulate the switching process of the microgrid from grid-connected operation mode to islanded operation mode to evaluate the performance of the control strategy in coping with the mode transition. Second, we focus on the load casting and switching operation in the islanding operation mode, which is a key test for microgrid stability and reliability. Through these simulation experiments, we verified that the designed control strategy can effectively manage the dynamic behaviour of the microgrid in different operation modes, ensuring system stability and continuity of power supply. The results show that the proposed control strategy is not only theoretically feasible but also effective in practical applications, providing an important reference for further research and practical deployment of microgrids.
