Experimental realization of DSTATCOM for Power Quality Enhancement Under Various Load Perturbations

In this paper, a Modified Instantaneous Reactive Power Theory (MIRPT) is proposed for DSTATCOM to abolish harmonic current and indemnify the reactive power under various load perturbations. The DSTATCOM is the building blocks of voltage source inverter with a common DC-link capacitor and a hysteresis band current controller for switching pattern generation. In order to proof the efficacy of th proposed controller based DSTATCOM for three different case studies are considered and then simulated. All simulations are executed by using MATLAB 2016. DSTATCOM performance has been found more effective to compensate harmonics under all scenarios of load disorder.
