Analysis and investigation on photovoltaic based microgrid system using power converters

Abstract

Many countries are presently implementing photovoltaic (PV) power systems connected to the grid. Grid-connected PV power systems must overcome considerable challenges to get maximum power while maintaining acceptable system quality. Maximum power point trackers (MPPT) and efficient converters are required to harness the available power in any weather predicament. The primary objective of this research is to examine the microgrid integration of solar systems within permissible total harmonic distortion (THD) limits, with the help of intelligent controller fed advanced power conversion devices such as symmetrical hybrid switched inductor (SL) and switched capacitor (SC) based boost converter and modified cascade multilevel inverter (CMLI). newlineA DC-DC converter along with MPPT controller is ideal for improving the output voltage of the PV panel. A symmetrical hybrid SL-SC (SH-SL-SC) boost converter is suggested for microgrid-connected PV systems since it has a high voltage conversion ratio. A cascaded feedforward neural network (CFNN) and fuzzy MPPT controller-based newline
