Photovoltaic energy storage system is a system that uses solar energy to store photovoltaic energy and generate electricity. Simply put, the photovoltaic energy storage system consists of two major devices: photovoltaic equipment and energy storage equipment. The photovoltaic equipment absorbs solar energy and converts it into electrical energy. The energy storage equipment stores the electrical energy generated by the photovoltaic equipment. When the photovoltaic system has insufficient power, The energy storage system will convert the stored electrical energy into the required AC power supply network for use. Specifically, it can be divided into photovoltaic off-grid power generation systems, off-grid energy storage systems, photovoltaic grid-connected energy storage systems, and microgrid energy storage systems. Next, let’s take a closer look at the advantages of photovoltaic energy storage systems.
The photovoltaic equipment of the photovoltaic energy storage system can absorb solar energy and convert it into electrical energy during the day. The energy storage equipment will store this electrical energy, and then convert the stored electrical energy into the alternating current required by the grid and release it at night. This is to a certain extent The realization of spontaneous self-use of photovoltaic power generation not only improves the efficiency of power generation, but also converts solar energy into electrical energy, greatly reducing the cost of power generation and electricity consumption.
The photovoltaic energy storage power generation system can convert solar energy into electrical energy, store it, and when needed, convert the stored electrical energy into alternating current required by the grid and release it for use. The electrical energy provided by this system is converted from renewable, cleaner solar energy. It is successful, which plays a role in saving energy to a large extent. In addition, the electric energy generated by this power generation system has fewer harmonics and is purer electric energy. Not only can it achieve energy conservation and emission reduction, but it can also improve the quality of the power grid.
Photovoltaic energy storage systems can realize flexible adjustment of power resources and provide corresponding protective functions for the power grid when a power grid failure or emergency occurs, which greatly improves the flexibility and safety of power resource utilization. It can also save non-renewable energy, improve the utilization rate of renewable energy, and realize the two-way flow of energy storage and power generation.
