This study evaluates an innovative on-site energy system (AWTHPS) combining variable-speed wind turbines, heat pumps (COP 3.2 at −10 °C), and hybrid thermal-battery storage to address wind curtailment and carbon-heavy heating in cold, wind-rich regions. A techno-economic model incorporating dynamic wind power curves, temperature-sensitive heat pump efficiency, and predictive control optimizes energy dispatch. Tested in a northern Chinese industrial park, the system reduces annual wind curtailment by 23.6%, lowers heating-related CO₂ emissions by 12.8 kg/m2, and achieves a competitive LCOE of $28.4/MWh—19% below coal-based heating. Sensitivity analysis shows policy subsidies reduce payback from 8.7 to 6.2 years, while a 10% battery cost drop boosts NPV by 31%. The modular, adaptive design offers scalable decarbonization for urban and off-grid heating in Class III wind areas. By quantifying storage benefits over turbine expansion, this work provides actionable strategies for integrating renewables into thermal systems, aiding policymakers and energy planners in cold climates.
