摘要
针对国家“双碳”目标及北方地区民居清洁供能的需求,以严寒地区某超低能耗民居为供能对象,设计了以光伏组件、风力发电机、集热器、空气源热泵为主要能量来源的储热储电一体化的清洁供能系统,建立多能互补的系统拓扑结构,从能源效益、环境效益和经济效益的角度,在多目标优化、供能系统和负荷需求的动态匹配约束条件下,采用Hooke-Jeeves算法,对系统关键组件及设备进行优化配置研究。结果表明,在最优容量配置及设计参数下,与以燃煤炉供暖、市政电网供电的传统供能形式相比,协同供能系统能够显著减少建筑在运行阶段的化石能源消耗量及污染物排放,具有良好的节能效益和减排效益。研究结果可为严寒地区设计超低能耗建筑,为以风能、太阳能为主的协同供能系统的设计及优化提供理论依据。
In response to the national“Dual Carbon Goals”and the demand for clean energy supply in northern regions,a clean energy system integrating wind and solar energy,as well as thermal and electrical storage,was designed for an ultra-low energy consumption residence in severe cold areas.The study conducted optimization and configuration research on key components and equipment of the system.A multi-energy complementary system topology was formed with photovoltaic components,wind turbines,collectors,and air-source heat pumps as the main sources of energy.From the perspectives of energy efficiency,environmental benefits,and economic benefits,the Hooke-Jeeves algorithm was applied to optimize the system.The constructed optimization model adheres to the principles of multi-objective optimization and dynamically matches the supply system with load demands.The results indicate that,under optimal capacity configuration and design parameters,compared to traditional energy supply systems relying on coal-fired heating and municipal power grids,the cooperative energy supply system can significantly reduce the consumption of fossil energy and emissions of pollutants during the building’s operational phase,demonstrating substantial energy-saving and emission reduction benefits.The research findings can serve as a theoretical basis for designing ultra-low energy consumption buildings and optimizing collaborative energy supply systems primarily based on wind and solar energy in severe cold regions.
