Power quality (PQ) concerns are considered the most prevalent issues related to the integration of renwable energy sources with electrical power networks. This paper tackles the enhancement of PQ issue regarding hybrid PV-wind system by using D-STATCOM. To do so, optimal parameters of D-STATCOM controller is determined by particle swarm optimization (PSO) and political optimization (PO). To examine the presented system with D-STATCOM based on PSO and PO, a comparison with static var compensator (SVC) is conducted under different operating conditions including voltage malfunction; sag, swell and harmonics distortion. The robustness and feasibility of the proposed technique for improving these issues are tested by using extensive simulation results. The proposed system along with D-STATCOM and its controller are simulated using MATLAB/SIMULINK. During the occurrence of voltage swell, the proposed D-STATCOM system can keep the voltage at appropriate levels, as well as raise the voltage to acceptable levels during the occurrence of voltage sag, in addition to the achieved reduction in total harmonic distortion.<
