An economic dispatch model incorporating wind power / Hetzer, J. in IEEE transactions on energy conversion, Vol. 23 n°2 (Juin 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°2 (Juin 2008) . - pp. 603 - 611 Titre : An economic dispatch model incorporating wind power Type de document : texte imprimé Auteurs : Hetzer, J., Auteur ; Yu, D.C., Auteur ; Bhattarai, K., Auteur Année de publication : 2008 Article en page(s) : pp. 603 - 611 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Power  generation  dispatch;  power  generation  economics;  wind  power Résumé : In solving the electrical power systems economic dispatch (ED) problem, the goal is to find the optimal allocation of output power among the various generators available to serve the system load. With the continuing search for alternatives to conventional energy sources, it is necessary to include wind energy conversion system (WECS) generators in the ED problem. This paper develops a model to include the WECS in the ED problem, and in addition to the classic economic dispatch factors, factors to account for both overestimation and underestimation of available wind power are included. With the stochastic wind speed characterization based on the Weibull probability density function, the optimization problem is numerically solved for a scenario involving two conventional and two wind-powered generators. Optimal solutions are presented for various values of the input parameters, and these solutions demonstrate that the allocation of system generation capacity may be influenced by multipliers related to the risk of overestimation and to the cost of underestimation of available wind power.
