The continuing penetration of combined heat and power (CHP)-based distributed generation (DG) has made urban electricity, water, and natural gas distribution networks increasingly interconnected. This paper analyzes the optimal network capacity and distribution of the CHP-based DG based on urban energy distribution networks by introducing an integrated system dispatch model. The electricity, water, and gas network models were designed and developed individually. The CHP-based DG model was developed to couple these energy distribution systems. The results indicate the optimal allocation of CHP-based DG by analyzing multiple factors and mutual impacts on operational performances of the CHP-based DG units and energy distribution networks. The designed typical gas system is capable of supplying sufficient natural gas for DG normal operations, whereas the present water system cannot support the complete recovery of the exhaust heat from large CHP-based DG penetration.
