This paper investigates the enhancement of frequency stability in a multi-machine power system (MMPS) integrated with an offshore wind farm (OWF) and an energy storage system (ESS) by replacing the conventional integral controller with a reinforcement learning (RL) controller for automatic generation control (AGC) of synchronous generators (SGs). The performance of the proposed RL controller under system disturbances is validated using dynamic time-domain simulations. The simulation results show that the stability of the studied system can be effectively improved by the designed RL controller located at the AGC of the SGs under disturbance conditions.
