Summary:This paper proposes the use of a dual-sign error control algorithm for a single stage, three phase, grid-integrated solar energy conversion system (SECS) with DSTATCOM (Dynamic Static Compensator) capability. The system consists of an SPV (Solar Photovoltaic) array, a voltage source converter (VSC), three phase non-linear load connected to the grid and a ripple filter. The VSC and the SPV array provide an active power to the grid and act as a DSTATCOM. This reduces the THD (Total Harmonic Distortion) introduced in the grid currents due to the nonlinear and unbalanced loads. It improves the power factor and maintains the voltage of the PCC (Point of Common Coupling). The extraction of maximum power incident on the SPV array is ensured by P&O (Perturb and Observe) algorithm for MPPT (Maximum Power Point Tracking). This system is studied by implementing a prototype using a SPV array simulator.
