ABSTRACT
Evaluation of Photovoltaic–
Hydro- Diesel hybrid system for electricity generation was carried out with
HOMER, using Michael Okpara University of Agriculture, Umudike (MOUAU) as a
case study. Data was obtained on monthly energy schedule of MOUAU, solar
irradiation intensity for a period of 12 years and the hydropower potential
/discharge rate of Anya River in MOUAU and optimized using HOMER. The data
collected are 279851.684kWh/yr, 14.77kWh/m2 and 580L/s,
respectively. The optimization result indicates that the hybrid power system
(HPS) generates a total energy of 474,901kWh/yr also, the energy generated by
each component of the HPS are in the fraction of 61%,37% and 2% for diesel,
hydro and solar systems respectively. Their unit costs per hour is given as USD
0.200kW/hr, USD 1.30kWh and USD0.064kW/hr. The hybrid power system also reduced
the rate of carbon dioxide (CO2) and other harmful emissions from
diesel generator. The renewable energy percentage of CO2 emission is
12% against 88% from diesel, of the total HPS emission. Photovoltaic– Hydro- Diesel
hybrid power system is found worthwhile for MOUAU, it is reliable, cheap and
environmental friendly. The net present cost (NPC) and the unit cost of energy
for the HPS is USD 1470938 and USD 0.312/kWh.
