与许多其他国家一样，电力市场的自由化和政府政治影响着瑞典的供热和电力供应。本文分析了补贴以及燃料和电力成本对瑞典代表性区域供热系统的影响。能源系统模型 MODEST（具有时间相关组件和边界条件的动态能源系统优化模型）用于优化热电厂的投资和运营。在电价较高的情况下，热电联产引入可能在所研究的系统中有利可图。根据目前的燃料价格，天然气联合循环将主要是有利的。较低的木片价格和政府补助将使生物质蒸汽循环热电联产更加有利。
Liberalisation of the electricity market and governmental politics influence heat and power supply in Sweden, like in many other countries. In this paper, the impact of subsidies and fuel and electricity costs on a representative Swedish district heating system is analysed. The energy system model MODEST (model for optimisation of dynamic energy systems with time dependent components and boundary conditions) was used to optimise investments and operation for heat and power production plants. At higher electricity prices, combined heat and power introduction may be profitable in the studied system. With current fuel prices, a natural gas fired combined cycle would primarily be favourable. A lower woodchips price and a governmental grant would make cogeneration with a biomass fired steam cycle more beneficial.
