“…The literature proposed several methods to enable WTGs to provide frequency response, namely virtual inertia and primary response, where the WTG controllers are modified to provide active power surge during frequency excursions [5,6]. Efforts are focused on making WTGs mimic synchronous generators response [7,8], where the reference speed, torque and power set-points are manipulated to secure a certain power reserve [9][10][11] that is highly dependent on wind speed (WS) just before and during frequency events, and the applied support concept [12]. This paper incorporates three key concepts, pitch de-loading, rotor over-speeding, and electrical torque over-loading to extract KE to enable wind power frequency support.…”

“…En las turbinas de viento, los parpadeos pueden ser causados por operaciones de conmutación y por las fluctuaciones de la potencia activa y / o reactiva en la operación continua (Attya & Hartkopf, 2013) Las mediciones de flicker según la norma 61400-21 deben ser realizadas, en una simulación en una red aislada al sistema nacional interconectado, con el fin de poder determinar las características del fenómeno (Tascikaraoglu et al, 2011).…”

(Recibido: 2014/04/30 - Aceptado: 2014/09/22)La matriz energética mundial está cambiando debido a que el consumo de energía en los últimos años se ha duplicado. En muchos países la instalación de centrales de energías renovables no convencionales se ha convertido en la solución a este crecimiento. La integración de este tipo de energías a la red eléctrica causa interés en el estudio de las propiedades eléctricas que afectan la producción de energía. Este documento es una revisión de los conceptos y fenómenos de calidad de energía y cómo estos se generan en parques eólicos. La eficiencia de los aerogeneradores se ve afectada por diversos factores, entre los cuales se destacan: las maniobras en subestaciones y los factores climáticos como las ráfagas de viento causantes de variaciones en la curva de potencia. El monitoreo constante en los sistemas eléctricos y el análisis de datos ofrece un alto potencial en la mejora de los procesos de producción y distribución de la energía.

“…Research efforts have been performed towards analyzing WPP contribution to frequency support (see for a review), also proposing different optimal algorithms that improve several aspects of the wind power conversion performance . However, few works commit the sharing of power reserve among the turbines inside a WPP.…”

Risk‐based optimal distribution of power reserves in wind power plants

et al. 2016

This paper employs the Conditional Value-at Risk, largely used in financial risk management, to specify the power reserve capacity of a wind power plant (WPP) under a risk metric. Evidences are shown here that other popular, simpler measure, the Value-at Risk, is inappropriate for that specification. Under this risk-based reserve metric, two programs are approached to optimally distribute a reserve request in a WPP subject to a given confidence level in the commitment. The most exhaustive of the two is a two-level formulation including a solution to the load power flow (LPF) in the WPP. By solving these two programs, for comparison with interior-point and heuristic solvers, conclusions are drawn. Notably, that a Pareto optimality occurs for stringent reserve requests; that putting off-line generators is financially more profitable than partial curtailments to respond to low reserve requests; and that in these cases accounting for losses through LPF-based optimization seems unnecessary.
