Feasibility Study Of Pvwindmicro Micro-hydrobiomass Hybrid System For Off-grid Electrification Of Selected Rural Areas In Ethiopia (case Study Eastern Gojam Zone Sinan District)

Out of the total population of Ethiopia about 85% live in rural areas and the accessibility ofrnelectric is estimated to be less than 1%. Lack of electricity in rural area has its own negativerneffect in human health and economic development. Since the area is dispersely populated andrnlacks of infrastructure, it is not easy to generate and distribute electrical energy from the mainrnrivers to the people living in rural areas. To solve this problem, the main suggestive solution isrnimplementing stand alone and hybrid power system. Micro hydro power together with solar PV,rnwind and biomass will enable electricity accessible to the rural areas.rnIn this thesis, the feasibility of microhydro/rnwind/solar PV and biomass hybrid power system isrnstudied in the selected rural areas of Ethiopia. The selected villages are located in North west partrnof the country known as “Kidusyohanes”,”Kundab” and” Debre”. The feasibility has beenrnstudied by collecting the necessary data and analyzing with the help of HOMER(HybridrnOptimization modeling for Electric Renewable) software. Data for microhydrornpower isrncollected from the field sought and Ethiopian Ministry of Water & Energy (MoWE). Solar andrnwind data are collected from National Meteorological Agency of Ethiopia and other data sourcesrnsuch as NASA and SWERA. For the biomass, the data is collected from Local Agricultural andrnRural development office to use the dung for the source of bio energy. The electric load for therncommunity is estimated and scheduled based on the socio economic activity of the people in thernarea. The peak primary load is found to be 212,237,155kw for kidusyohanes, Kundab and Debrernrespectively. The peak deferrable (water wheel pump and Irrigation pump) load is 4kw forrnkidusyohanes and Kundab, and 3.3kw for Debre. For the next 10 years, the load demand willrnincrease to 279.8(23.74%), 307.2(21.8%) and 195.0(17.36%)kw for Kidusyohanes, Kundab andrnDebre respectively.rnFrom the study the combination of Hydro/PV, Hydro/Biomass and PV is found with the least costrnenergy of $0.246/kwh, $0.218/kwh, $0.285/kwh for kidusyohanes, Kundab & Debre respectively.rnFor Kidusyohaness 34%, Kundab 49.6% and Debre 34.9% excess energy is found from thernsimulation result. For Debre the simulation result shows that the system is supported with 294KWrnPV/685 S4KS25P when the diesel is included and 285 kw PV/700 S4KS25P when the diesel isrnexcluded. The COE is $0.285 and $0.279$/kwh for system with & without diesel respectively.rnKey words:Feasibility,rnmicrohydrornpower, wind, solar, biomass, hybrid, load estimation and scheduling.
