Wind farms with HVdc delivery in inertial response and primary frequency control / Zhixin, Miao in IEEE transactions on energy conversion, Vol. 25, N° 4 (Décembre 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25, N° 4 (Décembre 2010) . - pp. 1171 - 1178 Titre : Wind farms with HVdc delivery in inertial response and primary frequency control Type de document : texte imprimé Auteurs : Zhixin, Miao, Auteur ; Lingling Fan, Auteur ; Osborn, D., Auteur Année de publication : 2011 Article en page(s) : pp. 1171 - 1178 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : HVDC  power  convertors;  frequency  control;  wind  power  plants Résumé : This paper develops a coordination control strategy for wind farms with line commutated converter-based HVdc delivery for participating in inertial response and primary frequency control. The coordination philosophy is to feedback the grid frequency and its derivative and adjust the delivery power of the HVdc link according to the feedback signals. The feedback loop employing the derivative of the grid frequency aims to improve the inertial response while the feedback loop employing the grid frequency deviation introduces a droop at the rectifier control loop. When the grid frequency is too high or too low, active power flow through the HVdc link will be ramped down or up. In turn, the wind generation will increase or decrease the blade angles to reduce or increase the captured wind power through pitch control. A case study demonstrates the effectiveness of the inertial enhancement and frequency droop in HVdc control. Simulation results in transient security assessment tool are given.
