A decision model for reducing active power losses during electric power dispatching

This paper focuses on the issue of power dispatching. In order to reduce fuel loss and fuel expenditure during power dispatching, a nonlinear mathematical model is proposed in this research. Slightly different versions of this model are used to calculate a steady-state regime, to minimize active power losses during the power despatch process, and to calculate some contingency regimes for emergency cases. An expert system that integrates the optimization methods and artificial intelligence techniques has been developed and implemented in a subsystem of the Romanian power system.
