So far, due to the lack of effective means to store a large amount of electrical energy in the power system, power generation, transmission, distribution and use of electricity must be completed at the same time. This requires the system to always be in a dynamic equilibrium state. Instantaneous imbalance may lead to safety and stability problems. . The emergence of high-power inverters provides an ideal interface between energy storage power supplies and various renewable energy sources and the AC grid. From a long-term perspective, the energy storage battery system composed of various types of power supplies and inverters can be directly connected to the user load in the distribution network to form a distributed power system. Through its fast response characteristics, it can quickly absorb user loads. The changes have fundamentally solved the control problem of the energy storage battery system.
There are many types of energy storage power sources that can be used in the energy storage battery system. The more common ones are superconducting energy storage (SMES), battery energy storage (BESS), flywheel energy storage, super capacitor energy storage, pumped water energy storage, and compressed air energy storage. Wait. Among various types of energy storage power supplies, battery energy storage system is a kind of energy storage power supply that is more suitable for power system use. It has relatively mature technology, large capacity, safety and reliability, no pollution, low noise, strong environmental adaptability, and convenience. Installation and other advantages.
The energy storage battery system is mainly composed of a battery pack and a converter. The converter is mainly based on a voltage source converter. The battery pack generally uses mature sodium-sulfur batteries or lead-acid batteries. Among them, sodium-sulfur batteries have obvious advantages in energy density, service life, and operating efficiency, so sodium-sulfur batteries are more widely used.
The essence of the converter is a large-capacity voltage inverter, which is an interface circuit between the energy storage battery and the grid, and realizes the two-way energy transfer between the battery's DC energy and the AC grid.
The energy storage battery system has a very wide range of applications in the power system, because it can quickly adjust the active power and reactive power of the access point, so it can be used to improve the stability of the system and improve the quality of power supply. When its capacity is large enough, it can even play the role of power peak shaving.
