新能源电采暖电力负荷建模

New Energy Electric Heating Power Load Modeling

对比分析了4种电能供暖热源的特性及优缺点,以及集中电采暖和分散电采暖两种方式的特性及优缺点。结合集中式供暖电加热锅炉的结构和工作原理,对电加热锅炉热效率和热力网的损耗进行分析,建立了集中供暖电力总负荷数学模型,最后运用所建模型对某供暖电负荷进行了预算。

According to the comparative analysis of the characteristics, advantages and disadvantages of four energy heating sources, it is found that electric boiler heating can not only access to grid scheduling but also make use of the lower price electricity for heat storage. While based on the comparative analysis of the characteristics, advantages and disadvantages of centralized electric heating and decentralized electric heating, we can find that centralized heating has the advantage of lower cost over decentralized heating because it not only has less influence on grid and users, but also is better access to grid scheduling. This paper analyzed the efficiency of electrically heated boiler and the loss of heat supply network on the basis of structure and operating principle of centralized electrically heated boiler. Then, a mathematical model of total centralized heating power load was constructed, and the heating load in Urumqi was budgeted through the model.
