Abstract
The present invention provides a battery-based grid energy storage for balancing the load of an power grid, wherein the energy storage comprises: a battery array; a bi-directional inverter unit; the bi-directional inverter system is configured to charge battery array using power from the power grid, or conversely, to transmit power from battery array to the power grid; a monitor system configured to detect the load, frequency and phase of the power grid, and control the bi-directional inverter system to charge battery array using power form the power grid, or conversely, transmits power from battery array to the power grid in accordance with the frequency and phase of the power grid so as to balance the load of the power grid, and meet the requirements during peak hours of electric power consumption.
