Abstract

The diminishing factor in the availability of fossil fuels has led to failure of the traditional grids to meet the ever-growing load demand in Zimbabwe. Hence, the utility provider prioritizes meeting urban demand over rural demand with its limited generation capacity. Therefore, this study addresses how to improve electricity access to rural areas in Zimbabwe through the design of a hybrid microgrid, that is powered by solar and wind energy sources, for an unelectrified rural location in Zimbabwe called Kagoro village in Mhondoro. The proposed hybrid model showed that a Photovoltaic-Wind-Diesel-Storage system with no tracking system has the lowest Levelized cost of electricity (LCOE) and net present cost (NPC) with a high renewable energy fraction (RF) of 97.7%. The proposed microgrid system could supply electricity to the target community at 0.223/kWh and 0.05790/kWh in standalone and grid-connected modes respectively with a payback period of 5.6 years, making it a good business case for would-be investors.
