The microgrid integrates the micro power supply, load, energy storage equipment and control devices to form a controllable and independent power supply system, making full use of the DG in the system, and its operation mode is flexible, but the control strategy has higher requirements. The microgrid has a dual role. For large power networks, it is regarded as a controllable unit that responds to the energy requirements of external networks in a few seconds. On the other hand, from the user's perspective, the microgrid can meet the special needs of different users. Demand, providing a variety of electrical energy. In this paper, three aspects of DG maximum power point tracking, battery bidirectional DC/DC converter control and DC bus energy optimization control are studied.
