本文主要研究分布式热电联产系统的优化问题。特别是，作者描述了一个混合整数线性规划模型，已开发的，以优化设计和运行的能源系统在有限的城市地区，建筑物配备了小型热电联产厂，并通过热分配网络连接;在所提出的模型中，多目标函数进行了优化，因为资本和运营成本，以及CO2排放量，考虑。该模型具有普遍的有效性，即使在本文件中报告的结果是相对于由住宅区和三级在城市阿伦扎诺在意大利北部的案例研究。此外，进行了比较研究，以量化的好处，在经济节约和CO2减排方面，有一个联合的热电分布式发电系统的建筑物，尽管使用锅炉来产生热量和购买电力从电网。
The present paper is focused on the optimization of combined heat and power distributed generation systems. In particular, the authors describe a mixed-integer linear programming model that has been developed in order to optimally design and operate an energy system in a limited urban area where buildings are equipped with small-size CHP plants and are connected by a heat distribution network; in the proposed model a multi-objective function is optimized, since capital and operating costs, as well as CO2emissions, are taken into account. The model has a general validity even if the results reported in the present paper are relative to the case study represented by a residential and tertiary district in the city of Arenzano in the North of Italy. Furthermore, a comparative study has been done in order to quantify the benefits, in terms of economic saving and CO2emission reduction, of having a combined heat and power distributed generation system in buildings in spite of using boilers to produce heat and of buying electricity from the grid.
