Introduction
Gravity energy storage technology, a new form of mechanical energy storage, converts various forms of energy such as wind and solar energy into gravitational potential energy for storage, which is then converted back into electricity when needed. To charge a gravity energy storage system (GESS), the motor is powered to lift up mobile blocks to a certain height for potential energy storage; to discharge, the system releases the blocks to drive the generator for power generation. Throughout such processes, automatic operation is realized via AI algorithms to store and supply energy according to the demand of the grid or users. GESS can regulate the instantaneous balance of grid power, boost the utilization efficiency of renewable energy resources, improve the quality of electricity, and enhance the reliability of electricity supply. It plays significant role in capturing random, fluctuating and intermittent wind and solar resources, and realizing the on-demand dispatch of renewable energy.
