Lithium Valley 500KWH 1MWH Energy Storage System

1.Scope of application
This system is suitable for the energy storage system ,it can be customized. The system is composed of multiple single batteries in series and parallel, and provides power for external equipment through a converter. The application of this energy storage system in the power grid mainly reflects In the following aspects:
1> Peak shaving and valley filling, by charging and storing energy during valley, and discharging energy during peak hours, reducing the electricity cost of enterprises or parks, and saving customers electricity costs

2>Demand response. When the short-term power consumption is greater than the capacity of the transformer, the energy storage system performs rapid discharge to meet the demand for electrical energy of the load.

3>Dynamic capacity increase, use energy storage equipment to replace the capacity of the voltage transformer at peak time, help users reduce the cost of transformer use, reduce transformer investment and expansion cycles, and conduct short-term power transactions on the power market trading platform in combination with load forecasts to maximize revenue.

4>Off-grid backup power supply provides uninterrupted short-term power supply for important loads when the power is interrupted, reducing the economic loss caused by the sudden power failure of the load.

2.Overall system design
This energy storage system consists of a 30-foot energy storage system container with a planned design capacity of 500kW/1MWh. The energy storage system container includes energy storage system, battery management system, PCS, UPS, EMS, lighting, fire protection, HVAC and distribution Auxiliary components such as electric access system, reserved for installation
/Maintenance channel; access to the power grid system of the plant area through the feeder cabinet of the power distribution room to achieve peak shaving, valley filling, demand management, energy saving, load balancing, dynamic capacity increase, power factor improvement and other functions. The electrical topology of the energy storage system is as spec listed.
