Product Introduction

The energy storage coordination controller is the core control device in the energy storage system, mainly used to coordinate the operation of multiple energy storage inverters (PCS) in the energy storage power station, achieve fast power response, frequency and voltage regulation, and ensure the stable operation of the energy storage system and the power grid.

Application

: Large scale energy storage power station
PMS is widely used in independent energy storage power stations and new energy supporting energy storage stations, supporting functions such as primary frequency regulation and dynamic reactive power regulation.

: Power grid frequency and voltage regulation
PMS provides frequency and voltage regulation services to the power grid by coordinating and controlling the energy storage system, enhancing the stability and reliability of the power grid.

: Fire storage combined frequency regulation
In the scenario of combined frequency regulation of thermal power and energy storage, PMS can optimize scheduling strategies and improve frequency regulation performance.

: Microgrid and Distributed Energy
PMS can be used for energy storage coordination control in microgrids, achieving source grid load storage interaction and optimizing energy scheduling.

: Black start function
PMS supports the black start function of energy storage systems, which can quickly restore power supply after grid faults.

: Fast power control
PMS can monitor the voltage, frequency, and power of the power grid in real time, quickly adjust the charging and discharging power of the energy storage system according to the demand of the power grid, and achieve millisecond level dynamic response.

: Multi PCS coordinated control
PMS can coordinate and control multiple energy storage inverters in a unified manner, supporting functions such as primary frequency regulation, dynamic reactive power regulation, inertia support, etc., to optimize the overall performance of the energy storage power station.

: Communication and Protocol Support
PMS supports multiple communication protocols (such as IEC61850, Modbus TCP/RTU, GOOSE, etc.) and can seamlessly integrate with devices such as EMS (Energy Management System), PCS, BMS (Battery Management System), etc.

: Safety and reliability
PMS adopts redundant design and supports dual network redundant configuration to ensure high reliability and stability of the system.
