| dc.description.abstract | Despite the efforts made so far in developing countries, access to energy and electricity
remain a challenge especially in Mali, particularly in remote rural areas. Mali is endowed with
good renewable energy potential, such as hydropower, solar energy, wind energy, and
biomass from agricultural residue. In this study various options of hybrid (renewable) energy
system using the available renewable energy resources for electricity are designed from rural
electrification perspective. This study assesses the feasibilities of hybrid renewable power
systems for the Sokolo community in Mali. The Hybrid Optimization Model for Electric
Renewable (HOMER) software was used to run the technical and economic analyses. The
feasible system design for the village of Sokolo’s load (biogas generator/ solar PV modules /
storages batteries /converter) was found to compose of 100 kW of solar PV array, 150 kW
biogas generator, 109,060 Ah batteries and 30 kW of converter/inverter to meet a total load
of 610 kWh/day and a peak load 136.71 kW .The hybrid renewable energy power system has
levelized cost of energy (LCOE) of US$ 0.279 /kWh, a net present cost (NPC) of US$
804,174, a CO2 emission of 490 kg/yr, a simple payback time of 8 years and a renewable
energy fraction of 100%. The selected system was compared to the scenario used by
AMADER (Malian agency for domestic energy and rural electrification) of diesel generator/
solar PV modules/ storage batteries/converter which has a lower LCOE and NPC for
supplying the same load at US$ 0.323 /kW and US$ 930,883.3 respectively. In addition
sensitivity analysis is performed to consider uncertainty in variables: biomass price, PV
equipment (modules, batteries, converter, and inverters) and biogas generator price multiplier
on the NPC and the LCOE of the selected system. | en_US |
