Thermodynamic Modeling and Analysis of a Novel Multi-Generation Energy System Based on Gas and Wind Turbine

A novel hybrid multi-generation system consisting of the following parts is proposed and thermodynamically analyzed: one gas turbine, one wind turbine, a district hot water, and a heat pump system for district heating, and a proton exchange membrane (PEM) electrolyzer to produce hydrogen as energy storage. This modeling is based on both one steam Rankine cycle and one organic Rankine cycle. The analysis for both energy and exergy is conducted, in order to comprehend the system performance, where values of 80.19% and 52.63% for energy and exergy efficiencies are found, respectively. Also an environmental impact assessment is performed and the effect of some parameters (ambient temperature, air compressor pressure ratio and wind speed) on carbon dioxide emission is investigated. During our investigation, some fuel is examined for combustion and fuel changes are reported. Furthermore, a study on the influence of enhancing renewable energy and reducing conventional system portion on production of a specified amount of electricity in an integrated system is carried out.
