The solar (PV) microgrid system is an integrated power system that incorporates solar energy, energy storage devices, Solar inverters, loads, and control systems. This system aims to achieve flexible and efficient utilization of distributed power sources, solve the problem of grid integration for a large number of distributed power sources, and enhance the reliability and stability of power supply. The PV microgrid can operate in both grid-connected mode, exchanging electrical energy with the main grid, and in islanded mode during grid failures or as needed, ensuring continuous power supply. Solar Arrays: The primary equipment that converts solar energy into DC electrical energy. Energy Storage Devices: Such as battery banks, used to store electrical energy to provide power support during insufficient sunlight or grid failures. Solar Inverters: Convert DC electricity generated by PV arrays into AC electricity for load use or grid integration. Loads: The objects powered by the system, including various electrical equipment. Control System: Monitors the operating status of the entire microgrid, ensures the coordination of all components, and performs mode switching and fault handling when necessary.  

In the field of energy storage, energy storage power stations play an important role. The application of energy storage power station technology runs through all aspects of power generation, transmission, distribution, and power consumption in the power system. It realizes peak shaving and valley filling of the power system, smoothing and tracking plan processing of renewable energy power generation fluctuations, efficient system frequency modulation, and increases power supply reliability. 1. What is an energy storage power station Energy storage power stations are power stations set up to regulate peak and valley power consumption problems. Energy storage power stations are composed of energy storage units and auxiliary facilities, access devices, and measurement and control devices. The establishment of energy storage power stations is to store the electricity that we are going to waste during low-peak power consumption periods and release it back to the power grid during peak power consumption to achieve the purpose of peak shaving and valley filling. 2. Composition of energy storage power station system Energy storage power station system can be divided into six main parts, namely renewable energy, energy transmission system, conversion system, storage system, management system and network access system.
