Abstract
In this study, to meet the electrical load requirement of Yalova University campus, grid-connected hybrid power generation simulations, and grid-independent hybrid power generation simulations were made with the Hybrid Optimization Multiple Energy Resources program. Eight alternative scenarios have been surveyed by employing annual solar radiation and wind speeds, fuel cost parameters, and energy storage need of the campus. Photovoltaic panel/wind turbine/diesel generator/battery/converter is proposed in hybrid energy system scenarios. In the analysis, net present value, cost of energy per unit, emission values, renewable energy rates and sensitivity analysis are calculated and presented in figures and tables. The energy production using renewable energy sources at 61.6%, 65.4% and 75.2% and the systems without renewables were investigated. As a result of the study, it was determined that the emission of the case whit 0% renewable energy is 7.3 times higher than the case with 75.2% renewable energy used. It was seen that the emissions of the scenario with 75.2% renewable energy used are 1.56 times less than the scenario with 61.6% renewable energy used.
