In recent years, micro-power grid industry has developed very rapidly. Then, more and more microgrid systems are built and connected to the grid. The electric energy generated by microgrid is greatly affected by external factors and has certain randomness and volatility, which has a huge impact on the stability of the grid-connected power system. The best way to improve this situation is to build energy storage system of microgrid plant. Therefore, in recent years, the equipment, capacity configuration and combined operation control of energy storage devices in microgrid field have become a hot topic in research and application demonstration. Facing the increasingly serious global energy crisis, the development and utilization of renewable energy has been attached great importance. Which radiation to the earths solar energy resources are very rich, green and clean solar energy will not harm our living environment, so it has been widely used by people. Photovoltaic power generation as a renewable energy is widely used, technology innovation. In order to improve the photoelectric conversion efficiency of photovoltaic power generation system, it is necessary to track the maximum power point in real time. Microgrid is the key to solve the problem of power system stability. Compared with the traditional AC distribution network, DC microgrid has technical and economic advantages and has a huge development prospect. This paper mainly focuses on the design and operation of photovoltaic grid-connected power conversion in DC microgrid. Based on the study of the common bus structure of microgrid and the mathematical models of different microgrids of photovoltaic, battery and inverter, different control strategies and practical operation modes are formulated. In the Matlab/Simulink simulation, a simple micro-grid model based on photovoltaic, energy storage and other micro-power sources is built, thus verifying the operation mode and control mode of different micro-power sources.
