小型居住建筑能源低碳化策略研究OA

Taking a small residential building in Beijing as an example,this paper analyzes the application of photovoltaic power generation in small residential buildings in detail,and explores the application of photovoltaic power generation in small residential buildings from the aspects of photovoltaic power supply analysis,building load change research and energy storage strategy research.Through the matching analysis of typical day,24-hour photovoltaic power generation and building energy consumption law in cooling season,transition season and heating season,this paper puts forward the energy storage form that domestic hot water energy storage takes priority and electrochemical energy storage takes second place in small residential buildings.The calculation method of determining the scale of electrochemical energy storage by typical daily analysis method is obtained,which is simple and convenient to determine the battery capacity,provides practical basis for the application of photovoltaic power generation in small residential buildings,and guides a large number of residential buildings to achieve low-carbon operation.
