Modeling and Analysis of Distributed Static Synchronous Compensator for Voltage Mitigation in Distributed System

Abstract

Distributed Static Synchronous Compensator (DSTATCOM) used in microgrid to balances the voltage (V_G) and current (I_G) at the load is presented in this psper . The proposed control method has to mitigate the voltage sag and harmonics than conventional method.The space vector modulation used to enhance the power factor at load side during normal operating condition. The mitigation of voltage problem is identified and rectified in the Distribution System (DS) thus the way of enhancing performance of the system. Renewable energy is used to balance the power across the load because the fault occurs in the source of the distribution system. The Photovoltaic(PV) based converter has generated the power and fed into the distribution line of the microgrid system. The voltage source inverter has converted the PV power for voltage mitigation. The analysis of DSTATCOM has been modelled and implemented in MATLAB/ Simulink.
