Predictive economic dispatch with time

In contrast with conventional Economic Dispatch (ED) problems which optimally allocates the generation of all dispatchable generating units, the economic dispatch with time is concerned with optimal allocation of unit generation projected for multi-intervals over a period of future. This paper aims at applying a new approach to the so-called dynamic economic dispatch based on the Dantzig-Wolfe decomposition method. The formulation of the dynamic dispatch problem in this paper is very similar to that of the conventional economic dispatch problem with the exception that temporal constraints are introduced for the dynamic economic dispatch problem. Even though the solution scheme for the dynamic economic dispatch is more complicated, the solution still shares the popular ”equal lambda” property per each time interval of the dispatch horizon.
