System Application Of Energy Storage System

    Energy storage technology is mainly divided into electricity storage and heat storage. The current energy storage methods are divided into three types: mechanical energy storage, electromagnetic energy storage and electrochemical energy storage.Energy Storage System
    Energy storage technology is mainly divided into physical energy storage, such as pumping energy, compressed air storage, flywheel energy storage, chemical energy storage (such as lead-acid batteries, redox liquid-flow batteries, sodium-sulfur batteries, lithium-ion batteries) and electromagnetic energy storage (such as superconducting electromagnetic energy storage, super capacitor storage, etc.) three major categories. According to the characteristics of various energy storage technologies, flywheel energy storage, superconducting electromagnetic energy storage and Super capacitor storage are suitable for short time large pulse power occasions, such as dealing with voltage sag and instantaneous power outage, improve the user's power quality, restrain the low frequency oscillation of the power system, improve the system stability, and so on, the pumped storage energy, compressed air energy storage and electrochemical battery can be suitable for large scale and large capacity applications, such as system peaking, large emergency power supply, renewable energy integration, etc.Energy Storage System
    Compressed air storage is another energy storage method which can realize large-scale industrial applications. Using this kind of energy storage method, the surplus electric energy is used to drive air compressor during the power grid load trough, and the air pressure is sealed in caves, abandoned mines and expired oil and gas wells. The compressed air is released during the peak load period to propel the gas turbine to generate electricity. Because of its high efficiency, long life, fast response and high energy conversion efficiency (about 75%), compressed air storage is one of the potential energy storage technologies. Superconducting energy storage Systems (SMEs) use the superconducting system to store magnetic field energies, power transmission without energy form conversion, with fast response (MS level), high conversion efficiency (Seum), Specific capacity (1-10/)/Specific power (104-105k) and other advantages, can be realized with power system real-time large-capacity energy exchange and power compensation. SMEs can fully meet the voltage support, power compensation, frequency regulation, improve system stability and power transmission capacity requirements of the transmission and distribution network.Energy Storage System
