“…STATCOM of 3 MW is connected at the point of common coupling (PCC). The four groups are exposed to a gust wind for nearly 10.5 s. The rated value of the wind speed is 15 m/s, however, the gust as simulated in [54] has a peak value wind speed 22 m/s and assuming all groups are exposed to the gust at the same time. The suggested model is shown in Fig.…”

This paper proposes constant active and reactive power control of a wind farm during gust using the supercapacitor (SC) and static synchronous compensator (STATCOM). The proposed technique is applied to Gabal El-Zayt wind farm which located in Red Sea region of Egypt with a capacity of 200 MW and equipped with doubly fed induction generators (DFIGs) and analyzed during gust wind. As the nature of wind is varying all time, the output power is changing continuously so energy storage system such as SC is required. SC is responsible for maintaining constant output active power by charging when there is excess in the output power of DFIG and discharging when there is a lack in the output power of DFIG. Reactive power compensation is achieved by connecting STATCOM to the power system. SC keeps reactive power constant however its value is improved by connecting STATCOM. Wind farm model is analyzed during gust with the proposed technique while active and reactive power performance is investigated. Firstly, the effect of connecting SC to each wind turbine is studied. Then the effect of connecting STATCOM to the electric power system is studied. Also, the effect of connecting SCs and STATCOM is studied. Finally, the impact of connecting additional STATCOM at different locations is investigated. Results show the proposed technique validity.

This paper presents a design of robust intelligent protection technique using adaptive neuro-fuzzy inference system (ANFIS) approach to detect and classify the fault types during various faults occurrence in large-scale grid-connected wind farm. Also, it is designed to determine the fault location and isolate the wind turbine generators located in the faulted zone during fault occurrence and reconnect them after fault clearance. The studied wind farm has a total rating capacity of 120 MW, where it consists of 60 doubly fed induction generator (DFIG) wind turbines each has a capacity of 2 MW. Moreover, the wind farm generators are positioned in 6 rows, where each row consists of 10 generators. The impacts of fault type, fault location, fault duration, cascaded faults, permanent fault and external grid fault on the behaviours of the generated active and reactive power are investigated. Also, the impacts of internal and external faults in cases of different transition resistances are investigated. The simulation results indicate that, the proposed ANFIS protection technique has the ability to detect, classify and determine the fault location, then isolate the faulted zones during fault occurrence and reconnect them after fault clearance. Furthermore, the wind turbines generators which are located in un-faulted zones can stay to deliver their generated active power to the grid during fault period.

“…El funcionamiento de estas máquinas se basa en: "el giro del rotor a una frecuencia diferente que la frecuencia de red" (Noureldeen & Rashad, 2013), obteniendo la máxima potencia frente a una velocidad variable del viento, logrando controlar la potencia activa y reactiva de forma independiente. (Noureldeen & Rashad, 2013).…”

(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.
