Abstract: At present, the extensive recognition on active compensators is pre-requisite for enhancing the PQ features in a three-phase 3-wire power distribution system. It is an exigent user related issue which is commenced by evading the mal-function of massive non-linear power-electronic controlled loads. This impacts on serious power pollution at position of common coupling and disrupts the voltage/current quality in a distribution system. A multi-objective DSTATCOM is the key choice for enhancing PQ features in a distribution system by utilizing attractive control strategies. The classical control strategies are more adversed with extreme switching losses due to the presence of high-order harmonic frequencies in a reference current sequence. This paper explores the novel fundamental frequency based current reference generation scheme for feasible functioning of DSTATCOM with greater efficiency and minimized switching losses. The critical performance of DSTATCOM with novel FFR-CG controller is validated by using Matlab/Simulink platform and simulation results are conferred.
