Photovoltaic Partial Shading Performance Evaluation With a DSTATCOM Controller

A solar photovoltaic distribution static compensator (SPV-DSTATCOM) under partial shading condition (PSC) is studied using a single-stage, 3-phase grid-connected mode. Under PSC, the performance of SPV-DSTATCOM and addressed issues such as active current sharing, reactive power control, harmonic elimination. Rejection DC offset with PSC an issue when conventional Proportional Resonant (PR) controller. As result this research, new improved PR (IPR) based second-order generalized integrator (SOGI) has been developed that unity gain at fundamental frequency greater rejection capability to address controller shortcomings. The proposed controller’s evaluated in both steady-state dynamic conditions varying loads different conditions. An experimental evaluation design assumptions also presented form comparison adaptive
