Frequency regulation is essential for the reliability of power grid with great load fluctuation and integration of new energies. Because of the wear and low-utilization cost, generators are not proper to deal with the load frequency control alone. Energy storage system (ESS) is introduced to coordinate with generators in automatic generation control, where ESS and …
