Supplying a renewable energy single phase microgrid from a biomass generator using a three phase induction machine

Microgrids that use distributed renewable energy sources have received great attention in recent years. In this study the microgrid incorporates a photovoltaic and a biomass generator, uses lead-acid batteries as storage in order to supply the loads of a vegetable greenhouse. The main objective of this paper is to investigate the performance of a three phase induction generator that supplies a single phase AC microgrid when converting the biomass energy to electrical energy. The generator is coupled directly to the microgrid single phase AC bus. The main purpose of using an induction generator for energy conversion is to reduce cost of the microgrid and to increase its reliability. The present study demonstrates that a three phase induction generator can be used successfully to produce power from the biogas generator and inject it in a single phase AC microgrid using a proper balancing network.
