Abstract
This paper describes the formulations and the solution algorithms developed to include uncertainties in
the generation cost function and in the demand on DC OPF studies. The uncertainties are modelled by
trapezoidal fuzzynumbers and the solution algorithms are based on multiparametric linear programming
techniques. These models are a development of an initial formulation detailed in several publications coauthored
by the second author of this paper. Now, we developed a more complete model and a more
accurate solution algorithm in the sense that it is now possible to capture the widest possible range of
values of the output variables reflecting both demand and generation cost uncertainties. On the other
hand, when modelling simultaneously demand and generation cost uncertainties,we are representing in
a more realistic way the volatility that is currently inherent to power systems. Finally, the paper includes
a case study to illustrate the application of these models based on the IEEE 24 bus test system.
