GREE Altairnano Containerized Energy Storage System was launched successfully in Nagarze, Tibet, for application in a 50MWp PV power station. It will track the output plan of the PV system and smoothen the PV power generation curve to increase grid-connection friendliness of the power station, which can solve the long-standing problem of PV power station being unable to connect to grid and the restriction on its power output due to unstable output. It not only offers a strong guarantee of clean energy supply in the economic development of the central area in Tibet, but also provides key technical support for the coordination, optimization and control of solar energy generation and storage system in high-altitude area.
