Application of Chemical Storage in Smart Grid and Analysis on Loss Reduction

Because of the characteristic of highly controllability and modularization, battery energy storage could be widely applied in the distributed renewable energy generation for improving the reliability of power supply and smoothing the load. The paper introduces the chemical energy storage technology especially the flow battery and designs the model of smart grid with the chemical energy storage devices. Then the paper gives the interface circuit between smart grid and energy storage, and simulates an actual distribution network with chemical energy storage device, the result shows that if the energy storage battery with proper capacity was connected to the distribution network at a proper position, it was effective in reducing the line loss.
