designing a grid-connected hybrid micro-grid: a case study in hamedan

Energy plays a critical role in the growth and development of societies, and universities are recognized as key drivers of economic progress. in light of declining fossil fuel reserves and global warming, adopting renewable energy sources, such as photovoltaic (pv) systems, has become increasingly essential. furthermore, the advantages of distributed generation are now more apparent than ever. many countries have developed various scenarios to eliminate fossil fuels from electricity generation, an approach that warrants serious consideration in iran as well. this study investigates the techno-economic feasibility and optimal design of a hybrid photovoltaic/diesel/battery power system intended to supply electricity to an academic center located in western iran. the technical aspects and economic viability of implementing such a system were evaluated using the homer (hybrid optimization of multiple energy resources) simulation tool. various configurations combining solar energy, battery storage, and diesel generators were analyzed and compared. the simulation results presented in this study demonstrate that, given the subsidized nature of energy carriers in iran, the implementation of hybrid energy systems is not highly recommended at this time.
