The significant way to support the electricity
sector and encourage the consumer to use renewable resources
in electricity generation in Egypt is investing energy produced
from hybrid renewable sources system with the grid. A hybrid
PV/wind turbine system is optimized as a core source of energy
for households in Egypt. The storage battery bank and diesel
unit are used as secondary energy sources. The surplus and
shortage of energy are invested with the utility grid.
Optimization results at interest rate of 12% indicate that cost of
energy (COE) and loss of power supply probability (LPSP)
when connecting PV/wind system with the utility grid are 0.024
$/kWh and zero against 0.131 $/kWh and 35.5% for gridindependent
PV/wind/battery system, respectively. This
corresponding to 81.7% reduction in COE. Thus, it is more
economic feasibility to connect PV/wind system with the utility
grid than grid-independent PV/wind/battery system.
