What is lithium battery energy storage? The working principle and advantages and disadvantages of energy storage power stations!
Energy storage, especially the lithium -ion battery energy storage market, is considered to have broad market space and diverse use scenarios. The advantages of lithium -ion battery energy storage technology have the advantages of high efficiency, flexibility, fast and fast speed, etc., and gradually occupy an increasingly important position in the power energy storage market.
The composition of the energy storage system mainly includes the battery storage system, the PCS variable system, the box variable system, the use variable system, the energy management system, and the monitoring system (SCADA system), primary and secondary cables.
Lithium ion battery energy storage technology is important to refer to the storage of electrical energy. The storage energy can be used for emergency energy, or it can be used for energy storage when the power grid is low. When the power grid is high, the energy is output energy for peak -to -peak to fill the valley and reduce the fluctuation of the power grid.
Working principle of lithium -ion battery storage power station:
The working principle of emergency lithium battery energy storage vehicles or Muwa -class fixed energy storage power stations is to transfer high -power lithium -ion batteries to single -phase and three -phase AC power through a inverter. You only need to choose the charging time to charge the battery pack freely. When the lithium ion battery packs overflow, you can call it at any time. Energy storage battery is an indispensable energy storage power component of the solar photovoltaic power generation system. The key function is to store the power of the photovoltaic power generation system, and the power supply is insufficient, and the load is powered on the load at night and emergency.
Lithium -ion battery storage power stations are generally used in new energy power stations, and there are relatively few applications in traditional power stations. Due to the unstable voltage, the time for wind power and solar power generation is uncertain, and the use of energy storage power stations as a power relay is more favorable for power grid operations.
Public data shows that there are 20 lithium -ion battery energy storage projects in my country, and the total installed scale has reached 39.575MW. Energy storage is one of the important means to solve the new energy wind power and photovoltaic intermittent volatility and realize the function of peak -cutting and Pinggu. Energy storage lithium -ion batteries are gradually valued as emerging application scenarios.
The advantages and disadvantages of lithium -ion battery energy storage power stations:
Advantages: It can solve the problem of electric vehicle battery scrap and reduce the cost of electric vehicles in disguise. It also solves the problem of the use of scenery and electricity, so that the landscape power has changed from garbage electricity to available electricity.
Disadvantages: 1. If the power storage performance of the battery must be recycled, the cost may not be affected by the industry, then you can only consider the battery steps;
2. Once an accident occurs in the battery storage power station, it is a major accident. Everyone knows the results of the previous explosions. The accident is huge and the environment is destructive.
Application scenario of lithium -ion battery storage power stations: Energy storage emergency power vehicles, energy storage fixed power stations, communication spare power supply and other aspects.
