Energy storage power stations are to regulate the power plant set up by peak valley power problems. Energy storage power stations are composed of energy storage entities and auxiliary facilities, access devices, and measurement and control devices. The establishment of the energy storage power station is to store the power that we need to waste from the low peak period of electricity, and re -release it to the power grid when the electricity is used to achieve the goal of peak -cutting valley.

Energy storage power stations can store electricity and release when needed, which can effectively solve the imbalance of power in time and space. The application of energy storage power stations runs through all aspects of power system power generation, power transmission, power distribution, and power consumption. Realize the peak -cutting of the power system, the smooth fluctuation of the power generation and the tracking plan processing of the renewable energy power, and the efficient system frequency adjustment, and increase the reliability of power supply.

The following is the main composition of the general battery energy storage power station system:

1. Transformer and high -voltage switch cabinet: Convert the grid voltage (10KV, 6KV or other levels of voltage) to the power grid into the level of the voltage required by the user's electrical appliance and power consumption (such as 0.4kV)

2. Low -voltage switch and control cabinet: control and management for charging and discharge and power output

3. Control system: The battery energy storage system is controlled by a programmable logic controller (PLC) and human -machine interface (HMI). One of the key functions of the PLC system is to control the charging time and rate of Residential Energy Storage System. Through standardized communication input, control signal and power supply, it is integrated with the rest of the system. It can be accessed by dialing or Internet. It has multiple defense layers to restrict access to different functions and provide customized reports and alarm functions for remote monitoring.

4. Power conversion system (PCS): The function of the power conversion system is to charge the battery and Discharge, and provide improved power supply quality, voltage support and frequency control to the local power grid. It has a complicated and fast -moving, multi -quadrant, dynamic controller (DSP), with a dedicated control algorithm, which can convert the output throughout the entire range, that is, the full power absorption from the full power to the full power output. There are currently two -way inverters.
