摘　　要：针对近海岛屿建筑用能现状,本文研究了我国夏热冬暖地区近海岛屿建筑风光混合供能系统的技术经济可行性。以某近海岛屿建筑为例,利用DeST软件对建筑能耗进行模拟,MATLAB对风光发电输出功率进行仿真计算,对比了四种系统方案的技术经济性。结果显示,风光柴蓄混合系统方案在各方面指标均优于其它几种系统方案,其等年值成本最低,较光柴蓄系统降低了13.63%。技术性上,岛屿无柴油情况下负荷缺电率最低,仅10.31%。全年污染物排放量最低,仅为33.41t。总体而言,风光柴蓄混合系统在近海岛屿建筑用能上的技术经济可行性最高。According to the current situation of energy consumption of coastal island buildings, this paper studies the techno-economic feasibility of the hybrid energy supply system of coastal island buildings in hot summer and warm winter areas. Taking a coastal island building as an example, DeST is used to simulate the building energy consumption,and MATLAB is used to simulate the output power of wind/solar power generation. The techno-economic of the four system schemes is compared. The results show that the wind/solar/diesel/battery hybrid system scheme is superior to other several system schemes in all aspects. Its equivalent annual cost is the lowest, which is 13.63% lower than that of the solar/diesel/battery system. Technically, the load power shortage rate was the lowest on the island without diesel,only 10.31%;The annual pollutant emission was the lowest, only 33.41 t. In general, the hybrid system has the highest techno-economic feasibility in the energy use of Coastal island buildings.
