Study of a solar-wind-hydrogen-gas-grid multi-energy system with CCHP distributed cooperative operation
Utilizing renewable energy sources such as solar, wind, and hydrogen helps reduce dependence on fossil fuels and mitigate greenhouse gas emissions. This study introduces a renewable energy system combining solar, wind, hydrogen, and natural gas resources with a combined cooling, heating and power system, absorption chillers and, air source heat pumps. The system is designed to dynamically meet the cooling, heating, and power demands. The system’s performance was analyzed using TRNSYS simulation, highlighting significant improvements in energy efficiency (ηen), primary energy saving rate (PESR), sustainability index (SI), and life cycle cost (LCC). Using response surface methodology, a multi-objective optimization was carried out to determine optimal configurations of photovoltaic panel area, solar collector panel area, and number of air–fuel cells. The results indicate that the optimal system configuration includes 4 wind turbines, 50 air–fuel cells, 500 m2 of PV panels and 5500 m2 of solar collector. This configuration achieves an ηen of 85.4 %, PESR of 87.3 %, SI of 3.785, and LCC of 4.119 × 106 $. The integrated system demonstrates enhanced energy efficiency, economic performance, and supply reliability, providing a viable pathway for renewable energy integration in building applications.
