In this paper, isolated Diesel generator set is integrated with static synchronous compensator (DSTATCOM) for harmonics elimination, reactive power compensation and injection of active power. The control of scheme of DSTATCOM is derived from instantaneous reactive power theory. The dc bus voltage is regulated to constant value with proportional integral (PI) controller of DSTATCOM. The controlling pulses DSTATCOM is carried out with hysteresis controller. The overall system consisting of DG set, DSTATCOM and nonlinear load simulation is carried out with MATLAB environment using Simulink and power system block-set toolboxes. The MATLAB modeling is performed for a synchronous generator coupled to a diesel engine, along with the three-leg VSC working as a PV-DSTATCOM. The simulated responses of PV-DSTATCOM with DG set are presented to verify the effectiveness of the control of PV-DSTATCOM for the compensation harmonics, reactive power and active injection without separate DSTATCOM.
