Solar PV-Fed Multilevel Inverter With Series Compensator for Power Quality Improvement in Grid-Connected Systems

Power quality difficulties arise as a result of Renewable Energy Sources (RES) integrating with the grid. Voltage swell, sag, and harmonic distortion occur on grid due to power issues, which have an impact customers. An inexpensive series compensator, like Dynamic Restorer (DVR), is best solution for overcoming aforementioned problems. In this article, solar PV integrated DVR novel multilevel inverter introduced address issues in The main objective proposed work develop 23-level enhance quality. addition, improved INC-MPPT technique designed boost converter maximum energy extraction from modules. Despite numerous benefits inverters, there exist several reliability challenges such fewer component counts reduced THD. suggested topology can able generate 23 levels output voltage asymmetrical DC sources. MLI has advantages reduction overall count, cost size inverter. Additionally, detailed mathematical analysis presented rotating dq reference frame control. dynamic performance evaluated balanced load implemented experimentally. Simulation results system are carried out using MATLAB/Simulink. dSPACE controller laboratory hardware prototype OPAL-RT real-time simulator setup well. show that design more effective at compensating sag improves significantly. THD obtained side lower, under IEEE standards.
