How does the Internal generator capacity and power supply reliability affects hybrid energy system sizing?

Abstract

Combining renewable energy sources to Internal Combustion Generator (ICG) systems for standalone applications is becoming popular due to higher depletion rate of fossil fuel resources and global concerns on green house gas emission- Modeling, simulation and optimization of such Hybrid Energy System (HES) was done in this study in order to investigate the impact of ICG and wind turbine capacity to Levelized Energy Cost (LEC)j and ICG Energy produced, further evolutionary e-multi objective optimization wets used to analyze the effect of unmet load allowance to I.EC and ICG energy produced in such scenarios Obtained results were compared with HOMER (existing software based on enumerative method); which shows that the Wasted Renewable Energy (WRE) increases with the reduction of ICG capacity increasing system sizing which could be reduced by a large fraction with slight allowance for unmet load.
