A Variable Admittance Shunt Capacitor Using Series Inverter for Filtering Harmonics of Distribution Systems

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