heal.abstract	Hellenic Aspropyrgos Refinery (HAR) is a state owned petroleum refinery with a crude oil capacity of 130,000 barrels per day. The electric and part of the thermal loads of HAR are covered by a combined-cycle cogeneration plant of 54 MWe capacity, which is interconnected with the utility grid. A variety of interdependent sources can be used to cover the loads, which vary with time. Therefore, questions such as the following arise: Given the needs in electricity and heat as well as the economic conditions at any instant of time, what source and at what load should be used if the objective is to minimize the operation expenses? Which is the economically optimum quantity of electricity to be bought from or sold to the utility grid? In order to answer these questions, an optimization procedure has been developed which is supported by a thermoeconomic analysis of the system and modeling of the performance of the main components. A computer program has been developed for the numerical solution of the optimization problem. In the present work, the optimization procedure and the computer program are described, numerical results are presented, a sensitivity analysis with respect to important parameters is performed and conclusions are drawn regarding the usefulness and further improvements of the program.	en
