摘要：
In response to the rising energy demands and environmental challenges, a multi-renewable system combining photovoltaic/thermal (PV/T), wind turbines, battery, borehole heat exchangers and Organic Rankine Cycle driven ground source heat pump is proposed. This system aims to enhance energy efficiency, achieve economic viability, and improve flexibility. The independent and interactive effects of area of PV/T, number of wind turbines, number of borehole heat exchangers, and mass flow per unit PV/T area are analyzed to assess their influences on energy efficiency (eta e), overall energy consumption (OEC), investment energy ratio (IER). Using robust response surface methodology and the Box-Behnken method, the optimal configuration is determined, revealing a PV/T area of 170.385 m2, 8 wind turbines, 5 borehole heat exchangers, and a mass flow of 0.285 kg/s per unit of PV/T area. This configuration produced promising outcomes: an eta e of 0.383, an OEC of-24656.88 kW & sdot;h/year, and IER of $0.120/kW & sdot;h. Compared to the ground source heat pump powered by the grid, this system achieves annual reductions in pollutants: 51,605.06 kg of COS, 167.42 kg of SOS, and 145.75 kg of NON. These findings provide valuable insights for integrated multi-renewable energy systems, highlighting their feasibility and flexibility.
