Abstract

Renewable energy resources like solar, wind and hydropower have time-dependent availability that limits continuous supply of electricity. This intermittency nature could be solved by combining different renewable resources that complement each other for stand-alone micro-grid system. For this study, solar PV, mini hydro and back-up battery are the components of the micro-grid. The study discussed in detail for AC-micro grid system of design, modeling, simulation and performance evaluation with economic feasibility analysis of the system for a rural village in Ethiopia. The study assesses the proper load demand for about 292 households and community service institutions in a village called Gora Got and Dibkan villages. This micro grid renewable energy power generation results 174.2kW hydro, 48kw solar PV power produced with 800w/m2 at Standard Test Conditions and 226.3kwh storage battery (for two days’ autonomy). The battery used in this micro grid system is to balance the demand and renewable power generation or for selected critical loads when these power generation, sources are not available or non-functional. The MATLAB Simulink toolbox is used to model the renewable energy sources, battery bank and conversion systems like DC-DC converters, rectifier and inverter with controller of each component. The system models individual components and analyzes the system voltage stability for the proper function of the micro-grid. The battery control strategy is done to protect from over charging and discharging processes. The feasibility of the system is analyzed using homer software and the energy cost is $0.080/kwh, which is feasible considering social, economic and other advantages gained from access to electricity.
