Effect of large dynamic loads on interconnected power systems with power oscillation damping controller (PODC)

Power systems are composed of dynamic loads. In this paper, the induction motors which are widely used in consumption units are considered as dynamic loads. This paper presents an analysis to investigate the effects of large dynamic loads on interconnected power systems with power oscillation damping controller (PODC). The PODC is designed based on the conventional method of linearization. An overview to design robust damping controller [19] is also presented and its effectiveness is analyzed and compared with power system stabilizer(PSS) for a single machine infinite bus (SMIB) system with increasing dynamic loads.
