基于建筑能源需求的光伏供能配置研究——以延庆山区某酒店建筑为例
摘要：以延庆山区某酒店建筑为例，研究了基于建筑能源需求的光伏系统供能配置。针对案例建筑的用能特点，建立了能耗模型，分析了用能强度及峰谷分布。综合考虑了建设用地、山地环境及建筑用能特点，采用光伏系统作为可再生能源产能系统，分别以建筑用能淡季峰值负荷、淡季谷值负荷、旺季峰值负荷、旺季谷值负荷作为基准选配光伏系统装机容量，根据投资静态回收期和年消纳率等指标进行经济技术分析，选择淡季谷值负荷配置光伏装机容量，不足电力配以风电，保证可再生能源系统较高的消纳率。
关键词：酒店建筑用能光伏系统装机容量能源供给消纳率

Research on configuration of photovoltaic energy supply based on building energy demand——Take a hotel building in mountainous area of Yanqing as an example
Abstract: Taking a hotel building in the mountains area of Yanqing as an example, this paper studies the energy supply configuration of photovoltaic systems based on building energy demand. According to building energy consumption characteristics, this paper establishes a building energy consumption model, and analyses the energy intensity of the building and its peak-valley distribution. Taking into account the construction land, the mountain environment and energy characteristics, the study adopts the photovoltaic system as the renewable energy production system. This paper configures the installed capacity of the photovoltaic system based on the off-season peak load, off-season valley load, peak-season peak load and peak-season valley load of building energy consumption, carries out economic and technical analysis according to the investment payback period and the annual absorption rate, and chooses the renewable energy supply scheme that uses the off-season valley load as the reference load of photovoltaic installed capacity, while the insufficient power is matched with wind power so that the renewable energy system can maintain a high absorption rate.
Keywords: hotel; building energy consumption; photovoltaic system; installed capacity; energy supply; absorption rate;
