Abstract: Microgrid is one of the newest technologies in power systems. Microgrid can usually has a set of distributed energy resources that makes it able to operate separate from power grid. Optimal operation of microgrids means the optimal dispatch of power resources through day and night hours. This thesis proposed a new method for optimal operation of microgrid. In this method, real-time pr...

Optimal operation of the combined heat and power system (CHP) depends on the degree of its flexibility and type of operation. So, the financial and technical challenges both in choosing and economic operation of these systems will be raised. In this paper, at first, a CHP system, including auxiliary boiler, absorption and auxiliary cooling system, has change to a flexible system by adding therm...
