Reactive power response of wind generators under an incremental network-loss allocation approach / De Oliveira-De Jesus, P.M. in IEEE transactions on energy conversion, Vol. 23 n°2 (Juin 2008)  

Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 23 n°2 (Juin 2008) . - pp. 612 - 621 Titre : Reactive power response of wind generators under an incremental network-loss allocation approach Type de document : texte imprimé Auteurs : De Oliveira-De Jesus, P.M., Auteur ; Castronuovo, E. D., Auteur ; Ponce de Leao, M.T., Auteur Année de publication : 2008 Article en page(s) : pp. 612 - 621 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Reactive power  wind power plants Résumé : The reactive power capability of wind generation (WG) producers can be used to provide volt/voltampere reactive (var) support in electrical distribution systems. In practice, the distribution network operator (DNO) is not able to dispatch reactive power of all generators, and such units are referred to as nondispatchable generators. Then, the reactive power of these nondispatchable generators is not a defined value, and it should accomplish the limits settled by national grid codes. This paper addresses the optimal reactive power provision of nondispatchable WG units under a loss allocation strategy based on incremental generation use of the system (GUoS) tariffs. The optimization problem is set from generators' viewpoint aiming to find the reactive power provision that minimizes the loss charges subject to operational constraints. Optimal solutions are compared with the DNOs mandatory dispatches using a reactive optimal power flow tool. Two test systems are analyzed: a 10-kV 28 bus and 60-kV 55-bus system throughout 672 and 168 h, respectively. The proposal permits to identify which units can be dispatched by the DNO due to its effect on the network.
