摘要
利用富余的风电、光电等可再生能源进行清洁供热,是解决我国北方地区弃风弃光问题和燃煤供热环境污染问题的有效手段之一。清洁供热的规模过大或过小都不利于供电、供热总系统的节能减排。以供电、供热化石能源消耗总量最小为目标,将规划问题和运行问题相结合,建立最优规划模型,研究清洁供热规模、电供热装置容量和储热装置容量的优化配置。通过对实际电网数据进行仿真计算,得到了最优规划结果以及清洁供热系统的运行情况,分析了可再生能源特性及限制火电供热电量占比对优化结果的影响,为清洁供热系统的发展提供了指导。
Clean electric heating utilizing abundant renewable energy sources such as wind power and photovoltaic power is an effective approach to promote renewable energy accommodation as well as reduce pollution from coal heating in northern China. Either bigger or smaller scale of clean heating would lead to inefficient utilization of energy resources in integrated electricity-heat energy system. An optimal planning model to optimize the scale of clean heating, the capacities of electric heating devices and thermal storage devices is proposed. The objective is to minimize fossil energy consumption in the integrated electricity-heat energy system, and planning and operation issues are combined in the model. The simulation for an actual power grid shows the optimization results and the operation of clean heating system. Effects of renewable energy characteristics and constraints on thermal power outputs are analyzed. The model provides guidance for planning of clean heating system.
