Control algorithm for coordinated reactive power compensation in a wind park / Diaz-Dorado, E. in IEEE transactions on energy conversion, Vol. 23 n°4 (Décembre 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°4 (Décembre 2008) . - pp. 1064 - 1072 Titre : Control algorithm for coordinated reactive power compensation in a wind park Type de document : texte imprimé Auteurs : Diaz-Dorado, E., Auteur ; Carrillo, C., Auteur ; Cidras, J., Auteur Année de publication : 2009 Article en page(s) : pp. 1064 - 1072 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  generators;  centralised  control;  dynamic  programming;  reactive  power  control;  wind  power;  wind  turbines Résumé : The penetration level of wind energy is continuously growing, and it is especially relevant in European countries such as Denmark, Germany, and Spain. For this reason, grid codes in different countries have been recently revised, or are now under revision in order to integrate this energy in the network taking into account the security of supply. This paper is related to reactive compensation, which is one aspect usually included in these codes. On the other hand, a great number of installed wind parks are formed by fixed speed wind turbines equipped with induction generators. The typical scheme for reactive compensation in this kind of wind parks is based on capacitor banks locally controlled in each machine. This configuration makes very difficult to follow the requirements of the new grid codes. To overcome this problem, a configuration with a central controller that coordinates the actuation over all the capacitor steps in the wind park is proposed in this paper. A central controller algorithm that is based on a dynamic programming is presented and evaluated by means of simulation. At this time, the proposed scheme has been installed at the Sotavento Experimental Wind Park (Spain) and it is currently being tested.
