CONTROL MICROGRID WITH RENEWABLE ENERGY SOURCE AND MULTIPLE CONVERTERS

Abstract

Micro-Grid technology is an emerging field and it is the interest area of researchers working specially on energy sectors. As our country is facing energy crises from many years and it is expected to reach severity level in future as the fuel prices are increasing. The single point of power generation cannot overcome the short fall currently facing the country. The industries for instance sugar and textile generating energy and exporting excessive energy to national grid. These days, the main focus for power generation is to utilize renewable energy sources. There are solar parks and wind energy farm are being constructed and their numbers are increasing day by day which are no doubt the major sources for reducing energy crises in the country. In this thesis, study on small scale power generation unit is being considered spread over a city to overcome energy crises. The terminology used for these small scale energy unit is Micro-grid. The problem with these micro-grid is that of synchronisation with the main grid that is when the main grid is off line, these microgrid should be synchronised in such a way that they can export sufficient energy to the main grid. This thesis addresses this issue by improving a control scheme for renewable energy resources and multiple convertors for energy storage system.
