通过多设备协调与双储能优化太阳能-风能-燃气驱动的冷电联供系统：需求响应与㶲-环境成本分析

Abstract Global energy demand continues to escalate amid industrial expansion and improved living standards, necessitating efficient integration of renewable energy sources. This study proposes a solar-wind-gas hybrid cooling and power system with multi-device coordination and dual electrical/cooling storage to address renewable energy volatility and fluctuating demand. Through demand response strategies, the system optimizes device scheduling to balance supply–demand while minimizing operational costs. An exergo-environmental cost method subsequently quantifies product-specific costs with energy-level differentiation. Results indicate that integrating wind turbines and photovoltaic/thermal units significantly reduces costs, with specific power and cooling prices at 0.134 $/kWh, and 3.431 $/kWh, respectively. Sensitivity analysis reveals optimizing exhaust allocation (≤0.5) and chiller COP (≈1.089) reduces system costs by 8.97 %, despite cooling costs rising 18.2 % and electricity costs falling 9.6 %, underscoring trade-offs in energy conversion efficiency. This work establishes a renewable-integrated framework with energy-level costing, advancing cost-efficient and sustainable energy system design.
