Multi-Input Transformer Coupled Bidirectional DC-DC Converter Based Grid-Connected PV-Wind-Battery for Induction motor Drive applications

Kollipaka Nagaraju, P.Ankineedu Prasad


Renewable energy sources have become a popular alternative electrical energy source where power generation in conventional ways is not practical. In the last few years the photovoltaic and wind power generation have been increased significantly. In this study, we proposed a hybrid energy system which combines both solar panel and wind turbine generator as an alternative for conventional source of electrical energy like thermal and hydro power generation. A simple control technique which is also cost effective has been proposed to track the operating point at which maximum power can be coerced from the PV system and wind turbine generator system under continuously changing environmental conditions. The wind and solar PV system are connected to the common load through Bidirectional DC-DC converter. The converter is designed to drive a induction motor directly from photovoltaic (PV) energy source and a wind generation. The modeling and simulation of hybrid system along with the Induction Motor drive is implemented and results verified by using MATLAB/SIMULINK.
