Abstract: At present, the power distribution system faces several concerns like sudden-load interruptions and acquires proliferation of quality power due to usage of non-linear loads. The extensive recognition on active compensators is pre-requisite for enhancing the PQ features and sudden-load interruptions in a three-phase 3-wire power distribution system. The integration of renewable energy into distribution as Distributed Generation (DG) furnishes the stable power demand under grid-islanding and grid-interconnection cases. A multiple-objective DSTATCOM is the key choice for enhancing PQ features and maintains stable power demand 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 reference current sequences. 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 in both PQ compensation and DG-Integration scheme by using Matlab/Simulink platform and simulation results are conferred with comparisons.
