Abstract: An energy storage system for balancing the load of a power grid (6) comprises: a controller (3), a plurality of energy storage tanks (1) connected in parallel, and a plurality of controllable switches (2) connected to the plurality of energy storage tanks (1) respectively, in which the controller (3) is configured to detect a frequency and a phase of the power grid (6) and thereby to control the controllable switches (2) to charge the energy storage tanks (1) using the power from the power grid (6) or to input the power from the energy storage tanks (1) to the power grid (6) in accordance with the frequency and the phase of the power grid (6) so as to balance the load of the power grid (6). The energy storage system may balance the load of the power grid (6) so that the power consuming demand can be satisfied during the peak time.

Abstract: A battery-based power station for balancing the load of a power grid comprises at least a battery array (10); a bi-directional inverter unit (20) configured to charge the battery array (10) by the power grid and provide power supply from the battery array (10) to the power grid respectively; and a monitoring-and-controlling unit (30) configured to monitor the frequency and the phase of the power grid to control whether to charge the battery array (10) by the power grid or provide power supply from the battery array (10) to the power grid, whereby the load of the power grid is balanced. The battery-based power station can balance the load of the power grid effectively.
