  7. Abstract:
  8. Increasing energy demand and at the same time, considering exhaustible fossil fuel resources has led to increase distributed generation for reducing energy loss and increasing efficiency of energy systems specially due to technical development on generation systems that meet environmental and energy policy concerns. One of the most important distributed energy technologies is Combined Heat and Power (CHP). CHP is small, high efficiency, low installation time and self-contained electric generation plant that can provide power for household applications, commercial or industrial facilities and hence its applications are overtly increasing. It can reduce power loss and enhance service reliability in distribution systems. Raising penetration level of CHP makes it more necessary to have an integrated view of energy systems including multiple energy carriers, instead of focusing on a single energy carrier. Optimal power flow, power generation and also optimal size of elements in multi-carrier energy systems by considering gas and electricity price variation, would be some results of this model. This thesis presents a generic framework for steady-state modeling and optimization of energy systems including multiple energy carriers which is named energy hub. The general system model includes conversion, storage, and transmission of various energy carriers. Since CHP is the most important part of an energy hub system, the author found the best technology of it by decision making software (Super comparison). Then the optimal size and operation of every energy hub elements have been calculated by GAMS software. At the end of this thesis, some useful economical parameters were determined with previous results in a real case study by applying COMFAR III
