In recent years, as a supplement for conventional large-scale power generation system, distributed energy system has got much comprehensive attention. In this study, in order to realize a low-carbon society, a distributed energy system has been promoted by taking into consideration the integration of combined heat and power (CHP), biomass energy and photovoltaic technologies, for an urban area in China. As an illustrative example, an investigation has been conducted of feasible distributed energy system for civilian facilities in a model area of Huzhou city, China. By using a design and evaluation model, five scenarios with different technology combinations have been analyzed for optimal adoption and operation. According to the simulation results, although having reasonable environmental merits, it is hard to diffuse the distributed energy system, especially some renewable resources, in the model area from the economic point of view. Currently, the most feasible distributed generation technology is natural gas CHP system, which leads to a cost reduction ratio of only 0.7%.
