Abstract
This study proposes optimal sizing approach for an Islanded MicroGrid (IMG) to determines the optimal component sizes for the IMG, such that the life-cycle cost is minimized. The proposed algorithm takes advantages of the typical meteorological year-based simulation and an economic evaluation model is presented. The proposed sizing approach identifies the global minimum, and simultaneously provides the optimal component sizes as well as the power management strategies. This proposed optimization algorithm is examined in a typical islanded load in Baghdad; Iraq and the results is compared. Our results show that integrating PV and battery storage significantly enhances system efficiency and sustainability, providing a more economical and environmentally sound alternative to traditional diesel-only setups.
