基于多能互补的区域能源系统优化模型
Optimization model of complementary district energy system based on multi-energy-sources
摘要：
根据我国城市紧凑型集约型发展的特点，建立了一种区域能源系统优化模型，可以统筹考虑常规能源与可再生能源，兼顾区域集中能源技术和分散能源技术，使多种能源多种技术在社区层面优化组合，优势互补。介绍了模型的建立过程，并以英国某生态城作为案例，通过该模型优化模拟得到了费用最低和在CO2排放量约束下费用最低的能源供求方案以及相应的能源系统管网布局。
Abstract：
According to the compact and intensive features of urban development in China, sets up an optimization model for the district energy system, in which conventional energy and renewable energy are overall considered, simultaneously central and distributed energy technologies are taken into account, so that a variety of energies and technologies could be complementary in optimization, combination and complementation at the community level. Presents the process of setting up the model. Taking an eco-city in UK as an example, obtains the energy supply and demand schemes and the corresponding energy system network layout under the minimal cost and the lowest cost with CO2 emission constraints by means of optimizing simulation of the model.
