Most of the research on district heating-cogeneration system deals with fixed servic area and energy demand. This paper presents a computational method for detecting location and service area of a district heating network with cogeneration, wich offers the maximum cost reduction compared with the existing energy system cost. The existing energy system consists of boilers and electric power from power grid. In the method the area in interest(city or province)is divided into small geographical zones. Its heat and electric demand and the necessary geographical coordinates characterize each zone. The basic parameter in the computational method is the Cost Reduction Factor(CRF), which is defined as the cost reduction rate that can be achieved if the existing energy system is replaced by a district heating-cogeneration network. The aim of the model is to connect zones in group, named cluster, with positive CRF. Effects of pipeline cost, fuel and electricity costs and hourly energy demand patterns on CRF are all included. The program is applied to an example area, and changes in CRF and CO_2 emissions are analyzed for different size of clusters(network area).
