The Solution for GBS of Cabinet Type

　　1.The solution for GBS of cabinet type

　　The solution should be connected to the end of power distribution grid to improve power distribution capability.

　　The grid battery station (GBS) of cabinet type is fitted in the compact vehicle-mounted container, thus flexible for moving and convenient for installation.

　　(1)Balance power grid

　　PCS and micro-grid controller are mainly used for power grid. When power demand is low, they can supply power to battery for storage via power distribution grid; while when demand is high, the power should be discharged to grid via battery to balance power load

　　(2)Receive dispatching order from power grid

　　The energy storage system strictly follows MODBUS RTU communication protocol, which can flexibly interact with grid’s remote terminal device and data collection and monitoring control system. Besides, it can receive dispatching order from grid’s auto monitoring system to realize the functions of remote signaling, remote measurement, remote controlling and remote regulation

　　(3)Standalone inverter power function

　　When power supply is cut off, the energy storage system can be worked as standalone power source to provide AC power to some important loads

　　(4)Support static/dynamic power grid

　　The energy storage system supports static and dynamic grid and provides active power and reactive power for power grid according to dispatching orders

　　(5)Several charging/discharging strategies

　　Various battery management systems (BMS) shall be provided for different users’ operating environments. The system can supply the best charging/discharging strategy to let it operate stably and efficiently

　　2.The solution of wind / energy storage system

　　The solution can better make up the randomness and intermittent of wind power and assist peak shifting of grid to improve its stability. Moreover, the surplus energy shall be stored to enhance utilization rate of wind power

　　The wind power grid-connection storage system is composed of wind power generator, conversion system, power grid, storage system and monitoring master station

　　The energy storage system can improve the grid balance and strengthen the grid stability by dynamically absorbing and real-time releasing energy. When average wind speed is high and mu
