Abstract

With Distribution static compensator (DSTATCOM) loads connected to stiff source cannot be protected from voltage disturbances. This paper provides a new fuzzy based control algorithm for multi-functional DSTATCOM is proposed to operate in voltage control mode which provides fast regulation at load point during disturbances and protects critical loads. During normal operating conditions the generated reference load voltages allow control of source currents. Simulation results are presented to show the efficiency of the proposed fuzzy based control algorithm and multifunctional DSTATCOM.
