Research on Principle and Control Strategy of Energy Storage Device Based on Lithium Battery Pack
The energy storage device can be used in new energy system,distribution system,UPS system and other occasions.The lithium battery,with its high power density and small size,is suitable for energy storage devices.However,the energy storage device composed of a single lithium battery pack is affected by the volatility and ran-domness of new energy and load,and its charging and discharging current is too large,which easily leads to deep charging and discharging.The energy storage device composed of multiple lithium battery packs can switch the lithi-um battery pack for charging and discharging,so the charging and discharging current and depth can be controlled,thus improving the life of the energy storage device.In order to verify the superiority of the energy storage device,a simulation model is built,and the simulation results show that the energy storage device can smooth the charging and discharging current of the lithium battery pack.
