摘　　要：采取新兴的可再生互补能源,配合分布式供暖技术解决我国西北塬地地区农村的供暖问题。选取渭北西部土桥镇的塬地太阳能电站和风力发电项目为物理模型,充分利用被弃的电功率,以被弃的太阳能风能互补发电,通过电热电缆给建筑供暖。采用OpenStudio和EnergyPluse能耗模拟软件计算塬地农村一住户四室一厅一厨的建筑供暖负荷,然后结合MATLAB/Simulink软件建立以被弃风电为热源并配置分布式储能的小型离网电热采暖系统。结果发现这种分布式的供暖系统可将电功率损耗减少至29.13%,供热效率可达88.55%,负荷失配率为2.74%。因此太阳能风能互补能源直流电分布供暖技术对解决塬地住宅冬季清洁供暖提供了一种可行方案。Emerging renewable complementary energy and distributed heating technology are used to solve the heating problem in rural areas in northwest China.This paper is based on the physical model of the plateau photovoltaic power station and wind power project in Tuqiao Town,western Weibei.It takes the abandoned solar and wind power complementary electricity to heat the building as the research object,makes full use of the abandoned electric power,and realizes heating through electric heating cables.Using OpenStudio and EnergyPluse energy consumption simulation software to calculate the heating load of the four bedrooms,a living room,and a kitchen of a household in the rural area of the plateau,and then combined with MATLAB/Simulink software to establish a system with abandoned wind power as the heat source and equipped with distributed energy storage small off-grid electric heating system.The result shows that this kind of distributed abandonment heating system can effectively reduce the power loss by 29.13%,the heating efficiency can reach 88.55%,and the load mismatch rate is 2.74%.The solar and wind energy complementary energy direct current distributed heating technology provides a reference for solving the clean heating of the residents in the plateau in winter.
