3Product introduction
3.1 Introduction of energy storage system
Energy Storage System (ESS) is energy storage, which refers to the storage of a form of energy in
the same form or converted into another form of energy through a medium or equipment. A
cyclic process in which a specific form of energy is released. The energy storage system is an
important part of the "generating-transmission-transformation-distribution-utilization" link of
the power grid, and an indispensable part of the energy Internet and smart energy.
Power generation side: The energy storage system can participate in the rapid response
frequency regulation service, improve the reserve capacity of the power grid, and can provide
continuous power supply to end users from renewable energy sources such as wind energy and
solar energy. Overcome its volatility, intermittent and other shortcomings;
Transmission and distribution link: The energy storage system can effectively improve the
reliability of the transmission system and improve the quality of electric energy;
User side: The distributed energy storage system optimizes electricity consumption under the
coordinated control of the smart microgrid energy management system, reduces electricity
consumption costs, and maintains the high quality of electricity.
In the ESS, the energy conversion is mainly realized by the power conversion system (PCS for
short), as shown in Figure 3-1below:
