A Solar-PV Integrated Novel Reduced-Switch UPQC Device for Power-Quality Improvement

Recent days, the efficient distributed generation scheme is encouraged for obtaining required load demand by employing solar-PV energy generation complying with power-quality limitations. Amid of various custom-power devices, the Universal Power-Quality Compensator is the best choice for compensation of both voltage and current allied power-quality issues in distribution system. But, the traditional UPQC device consists of more switching devices which increases the dv/dt stress, switching loss, low efficiency performance, etc. In this regard, a novel reduced-switch UPQC has been proposed with the requirement of fewer switch elements over the traditional UPQC device. The proposed RSUPQC device is used for enhancing power-quality features and DG integration scheme for stabilizing the utility-grid fluctuations by using novel modulation-rate control technique. The performance of proposed RSUPQC device is verified in both power-quality enhancement and DG integration modes by using Matlab/Simulink tool, results are presented.
