Solar photovoltaic (PV) systems are increasingly being installed in the distribution systems because of their decreasing cost and various advantages. This paper deals with the design and implementation of Photovoltaic Distribution Static Compensator(PV-DSTATCOM). The work has been done in MATLAB/SIMULINK. Perturb and Observe algorithm is used to simulate the proposed work. Maximum Power Point Tracking (MPPT) using Perturb and Observe algorithm is used to obtain duty-ratio for controlling the switching devices of DSTATCOM. The results have been given showing the waveforms of three-phase voltages, currents, capacitor voltage and instantaneous power, both for the case of constant irradiance and for the case of varying irradiance.
