Centralized control for optimizing microgrids operation / Tsikalakis, A.G. in IEEE transactions on energy conversion, Vol. 23 N°1 (Mars 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 N°1 (Mars 2008) . - pp. 241 - 248 Titre : Centralized control for optimizing microgrids operation Type de document : texte imprimé Auteurs : Tsikalakis, A.G., Auteur ; Hatziargyriou, N. D., Auteur Année de publication : 2008 Article en page(s) : pp. 241 - 248 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Distributed  power  generation;  optimisation;  power  distribution  control;  power  grids;  power  markets Résumé : Microgrids are low-voltage (LV) distribution networks comprising various distributed generators (DGs), storage devices, and controllable loads that can operate either interconnected or isolated from the main distribution grid as a controlled entity. This paper describes the operation of a central controller for microgrids. The controller aims to optimize the operation of the microgrid during interconnected operation, i.e., maximize its value by optimizing the production of the local DGs and power exchanges with the main distribution grid. Two market policies are assumed including demand-side bidding options for controllable loads. The developed optimization algorithms are applied on a typical LV study case network operating under various market policies and assuming realistic spot market prices and DG bids reflecting realistic operational costs. The effects on the microgrid and the distribution network operation are presented and discussed.

Control of variable speed wind turbines in islanded mode of operation / Kanellos, F. D. 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. 535 - 543 Titre : Control of variable speed wind turbines in islanded mode of operation Type de document : texte imprimé Auteurs : Kanellos, F. D., Auteur ; Hatziargyriou, N. D., Auteur Année de publication : 2008 Article en page(s) : pp. 535 - 543 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Distributed  power  generation;  power  generation  control;  wind  turbines Résumé : Nowadays, technology evolution and deregulation of the electric utility industry enable distributed generation (DG) to play an increasing role in locally satisfying the expanding power demand. In this paper, the islanded operation of an electrical grid supplied by wind turbines, which belong to the most rapidly expanding DG technologies, is studied. Control strategies for power electronics interface of variable speed wind turbines, ensuring fast control of frequency and voltage, are proposed.

Optimal control of variable speed wind turbines in islanded mode of operation / Kanellos, F. D. 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. 1142 - 1151 Titre : Optimal control of variable speed wind turbines in islanded mode of operation Type de document : texte imprimé Auteurs : Kanellos, F. D., Auteur ; Hatziargyriou, N. D., Auteur Année de publication : 2011 Article en page(s) : pp. 1142 - 1151 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Angular  velocity  control;  asynchronous  generators;  distributed  power  generation;  electricity  supply  industry  deregulation;  optimal  control;  power  generation  control;  wind  turbines Résumé : Nowadays, technology evolution and deregulation of the electric utility industry enable distributed generation (DG) to play an increasing role in satisfying locally the power demand. In this paper, an optimal control method for variable speed wind turbines (VSWTs) in islanded mode of operation is presented. Aim of this control system is to minimize the necessary control action in order to track the active power demand. Consequently, reduced mechanical stresses and equipment damages are achieved, while system stable operation and reliability are ensured. The proposed control scheme can be applied to any type of pitch controlled VSWT. For evaluation purposes, it is applied to a VSWT equipped with a doubly fed induction generator. Finally, simulation results are presented and general conclusions are drawn.
