The effect of environmental emissions on electricity interchanges between interconnected systems

This paper presents analysis and evaluation of the environmental impacts of electricity interchanges between interconnected systems. Power interchanges affect the utilization of the individual generation systems and consequently the emissions by each system; it is anticipated that power interchanges have a different environmental impact for each system. The analysis is performed using two computer models developed at NTUA: PROSIM for probabilistic production simulation and POWEREX for scheduling the economic interchanges between the power systems. A complete study considering the power systems of Greece, and variants of the Italian and Bulgarian systems is presented in detail.
