Frequency regulation (Frequency Regulation) is an essential task in power systems, aimed at maintaining the stability of grid frequency. The frequency of a power system typically needs to be kept within a specific range, such as 50 Hz or 60 Hz, to ensure the proper operation of all electrical equipment. Here are several common methods of frequency regulation:1. Primary Frequency ControlPrinciple: Primary frequency control is achieved by automatically adjusting the output power of generating unit
