Abstract
This thesis presents the design of a hybrid electric power generation system utilizing both wind and solar energy for supplying a cluster of three micro and small enterprises (MSEs) working on wood and metal products at the Welenchity site. The work was begun by investigating wind and solar energy potentials of the desired site, compiling data from different sources and analyzing them using software. The wind speed and solar irradiation data for the site understudy are collected from the National Metrological Agency (NMA) and analyzed using the software tool HOMER. The results related to wind energy potential are given in terms of the monthly average wind speed, the wind speed PDF, the wind speed CDF, the wind speed DC, and power density plot for the site. Whereas the solar energy potential, has been given in the form of solar radiation plots for the site. According to the results obtained through the analysis, the site has abundant solar energy potential and the wind energy potential is unquestionably high enough to be exploited for generating electric energy using wind turbines with low cut-in wind speed. The design of a standalone PV-wind hybrid power generating system has proceeded based on the promising findings of these two renewable energy resource potentials, wind and solar. The simulations and design has been carried out using the HOMER software. By running the software the simulation results which are lists of power supply systems have been generated and arranged in ascending order according to their net present cost (NPC). Sensitivity variables, such as range of wind speed, solar radiation and diesel price have been defined as inputs into the software and the optimization process has been carried out repeatedly for the sensitivity variables and the results have been refined accordingly. The model developed is fairly general and may be adequate for preliminary results for energy consumption cost for MSEs willing to adopt renewable energy sources. Therefore the most economical scenario is using wind-PV –Diesel Generator-Battery hybrid system as stated before.
