Abstract :
This paper presents the improvement obtained in voltage profile of power systems with dynamic loads using STATCOM, under various transient conditions. A composite dynamic load model, consisting of three-phase induction motors and impedance loads, is used to capture the actual load characteristics. The voltage source inverter-based STATCOM is modeled using the dynamics of the dc link and incorporating the widely used PI control scheme, operating in voltage control mode. Simulation of a modified four-bus Heffron-Phillips test system shows the interaction of the STATCOM with dynamic load in an effort to improve the system dynamics under various transient conditions
