As an important form of receiving renewable energy, microgrids can be a useful supplement to large grids, which can solve the power supply problem of residents in remote mountainous areas, pastoral areas, and islands. Modeling and simulation of energy management for microgrid operation characteristics with wind and solar storage have important practical significance. In this paper, mathematical models of photovoltaic cells and wind power systems are established, simulation models are constructed, and their respective characteristics are simulated and analyzed to verify the correctness of the mathematical models. A simulation model of maximum power point tracking for wind and solar power systems was established based on the respective shortcomings and limitations of independent operation of wind power systems and photovoltaic systems. According to the simulation results, it can be seen that the maximum power control technology used in this system can achieve maximum power tracking for wind power generation systems and photovoltaic power generation systems. The simulation results verify the correctness of the system and the feasibility of the control strategy.
