Abstract: This paper is written for the study of micro-grid design and analysis conducted at a rural village near to Kombolcha town. The methodology followed to design and analyze the micro-grid system was by using of HOMER pro software. The hybrid system has been designed with appropriate wind turbine generator, diesel generator and solar panel as components of local micro grid supply system. The design aimed primarily to create an isolated micro grid system used to supply a particular load groups in a reliable and cost effective electric power for the rural village under study. The design is done mainly by considering the present daily load profiles. But the future forecasted household AC loads of the rural village is also taken into consideration during the design process.2 AC pumps presently operating for agricultural irrigation purposes of the rural communities are also included into the present daily load profile of the rural village. The necessity of studying such a system is due to the fact that most rural villages in Ethiopia are not directly connected to the already existing electric supply network/grid. The majority of rural village homes which don’t have access to the National electric supply network usually use diesel generator set or car batteries as preferential power sources for meeting their household electric power supply demand as well as to run pumps for agricultural irrigation purposes. These power sources are not cost effective and not reliable from the point of availability of cheap diesel to the rural village to run generator and requirement of repeated charging cycles of batteries. Analysis indicates that Hybrid power supply system which uses two or more power sources will give better and reliable power source with high cost effectiveness.
