区域供热可能有助于减少环境影响和能源成本，但政策工具和废物管理可能会影响业务。MODEST能源系统优化模型已用于50个城镇、地区和一个国家。通过线性规划，找到以最小成本满足能源需求的投资和操作。本文介绍了应用MODST的市政公用事业，它使用多种燃料和热电厂。该模型反映了每日和每月的需求波动。林雪平效用的几项研究进行了审查。这表明，边际热成本较低，在夏季;一个新的废物或木材燃烧热电联产厂比天然气燃烧联合循环更有利可图;材料回收的纸张和硬塑料是可取的废物焚烧从能源效率的观点;并考虑到外部成本提高木材燃料的使用。在这里，排放限制是用来显示如何化石燃料热电联产取代二氧化碳从煤冷凝厂。
District heating may help reduce environmental impact and energy costs, but policy instruments and waste management may influence operations. The energy system optimisation model MODEST has been used for 50 towns, regions and a nation. Investments and operation that satisfy energy demand at minimum cost are found through linear programming. This paper describes the application of MODEST to a municipal utility, which uses several fuels and cogeneration plants. The model reflects diurnal and monthly demand fluctuations. Several studies of the Linköping utility are reviewed. These indicate that the marginal heat cost is lower in summer; a new waste or wood fired cogeneration plant is more profitable than a natural-gas-fired combined cycle; material recycling of paper and hard plastics is preferable to waste incineration from an energy-efficiency viewpoint; and considering external costs enhances wood fuel use. Here, an emission limit is used to show how fossil-fuel cogeneration displaces CO2from coal-condensing plants.
