Abstract: 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 CO2 emissions, 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 CO2 emission 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.
