An isolated renewable energy source based regulated single phase power supply using multilevel cascaded H-bridge converter

In an isolated and rural locations where the energy is derived from renewable sources, the load will suffer from large fluctuations due to the unpredictable nature of the underlying phenomena (wind or solar). This paper presents the implementation of practical control for standalone renewable energy source able to feed an isolated load with regulated voltage and satisfactory energy quality in remote areas. The proposed control scheme is verified both by simulation and through experiments. The simulation and experimental results are presented.
