So. Orero et Mr. Irving, LARGE-SCALE UNIT COMMITMENT USING A HYBRID GENETIC ALGORITHM, INTERNATIONAL JOURNAL OF ELECTRICAL POWER AND ENERGY SYSTEMS, 19(1), 1997, pp. 45-55
In the new competitive electricity supply industry, there is a renewed
interest in algorithms that can provide savings in operation costs. A
n optimal scheduling of generators can provide substantial annual savi
ngs in fuel costs, but this highly constrained non-linear mixed intege
r optimisation problem can only be fully solved by complete enumeratio
n, a process which is not computationally feasible for realistic power
systems. In the recent past, evolutionary computation techniques have
been applied to the solution of the unit commitment problem, but when
implemented as stand alone systems, they suffer from computational ti
me limitations, especially when the systems are scaled up. This paper
proposes a hybrid genetic algorithm incorporating a priority list unit
ordering scheme to solve the generator scheduling problem. Test resul
ts on networks with up to 110 generators are presented and the results
demonstrate the viability of the hybrid GA method for unit commitment
in realistic power systems. Copyright (C) 1996 Elsevier Science Ltd
