Abstract :
In this paper, a modified Q-Learning algorithm is proposed to enhance the convergence speed of the conventional algorithm to reach a near optimal policy. This is achieved by using selective initial state criteria (SISC) instead of choosing initial state randomly in each episode. The proposed method is implemented to control power system stabilizers to enhance power system stability. The validity of modified Q-Learning has been tested on a 2 area, 4 machines power system.
