  7. Abstract:
  8. In recent decades, rapid growth in the utilization of energy resources has led to using a system of combined power, heating and cooling due to their high efficiency. Losses of electrical power transmission and distribution networks are also another reason to emphasize using the combined production systems. Today, the use of small scale combined production systems at the same time, competitive with electricity generated from renewable energy technologies have also emerged. The present study was undertaken to answer questions on the topic of disrict heating and cooling system design with power that can be occur. For this purpose, first the governing mathematical equations are expressed and then the modeling of these equations is done by GAMS software through mixed integer linear programming. The size optimization of energy conversion units such as boilers, chillers and power production units and also the optimal location of each technologies are investigated in this thesis. By considering three scenarios including centralized, decentralized and conventional approach, optimal routes of district heating and cooling networks have been specified for these scenarios. Finally, with respect to the important parameters of our problem such as price of electricity, price of gas and heating demand, the variations of optimal solutions have been investigated by sensitivity analysis
