Multilevel Converter With Nearest Level Control for Integrating Solar Photovoltaic System

Also Available Domains |Multilevel Converters

Project Code :TEPGPS608


The main objective of this project is Implementation of solar multilevel converter based solar photovoltaic system for medium voltage applications with nearest level control.


In this paper a new Scott-ternary solar multilevel converter (ST-MLC)-based solar photovoltaic (PV) system for medium voltage applications. This system employs a single solar PV array as an input source and two voltage source converters (VSCs) to feed a three-phase grid. Solar power is fed from a two-phase to a three-phase medium voltage grid with balanced grid currents. The legs of VSCs are cascaded to form a two-phase system. The multi winding transformers are connected in a Scott manner to develop a nine-level three-phase power conditioning system. The turn ratios of the transformers have ternary progression for the generation of higher levels. The modeling of the system is presented, and a closed-loop nearest level control strategy is incorporated to have minimum losses. Simulation results show the performance of the solar PV system under steady-state and dynamic irradiance.

Index Terms—Fundamental switching, multilevel converters (MLCs), photovoltaic (PV) array, power quality.
