“…Possible initial cause was that storms in the isolated area led to outages of several lines. Islanding occurs when a part of a power Interconnection containing generation and load is isolated from the remainder of the system [7]. If multiple disturbances occur, synchronism of interconnected power systems could be lost, in which case out-of-step protection systems can help to detect angular instability and isolate the asynchronous part to preserve stability [8].…”

The North American frequency monitoring network (FNET) takes GPS-synchronized wide-area measurements in a low-cost, easily deployable manner at the 120 V distribution level. A situational awareness system has been implemented on the server located at Virginia Tech to detect and analyze power system disturbances in near-real time. Power system disturbances are examined in this paper based on wide-area frequency, voltage and phase angle data from FNET. Frequency characteristics of events in three major North America power Interconnections are investigated. Typical frequency patterns of generation loss and load drop events are analyzed for the Eastern Interconnection (EI), the Western Electricity Coordinating Council system (WECC), and the Electric Reliability Council of Texas system (ERCOT). Several significant disturbances in the EI are also discussed. The recordings and analysis show that a great deal of valuable information about dynamics in bulk transmission systems can be obtained at a lower voltage level.

“…Due to the technological innovations related to the energy conversion in the last decade, it is now possible to have competitive electricity generation with DG units. Many papers have been presented in literature regarding the sizing, placement, and reliability of DG [1,2]. The main merits of DG can be listed as follows: reduction of power loss, voltage profile improvement, power quality improvement (in some cases), possibility to exploit CHP (Combined Heat and Power) generation, less polluting emissions (with respect to traditional plants) [3].…”

This paper proposes a new islanding detection method for use in a small-scale, grid-interconnected distributed generator system. The proposed islanding detection method is based on voltage fluctuation injection, which can be obtained through high-impedance load switching on the grid periodically. The correlation factor between the periodic switching signal and the perturbed voltage is then used as an islanding detection index in the proposed islanding detection method. Experimental results demonstrate the principles of the proposed technique.

“…The connection of DG units raises new challenges [7,8], being islanding one of the main concerns [8][9][10][11][12][13]. Although DG may successfully operate in island if there is a balance between load and generation, islanded operation is not generally allowed for some major reasons [10][11][12]:…”

RESUMENEste artículo presenta las características principales de una librería de módulos desarrollada para representar dispositivos de protección de una red de distribución de energía eléctrica con generación distribuida (GD). El impacto de la generación distribuida depende, entre otros aspectos, del diseño del sistema de protección y de la coordinación entre los diferentes dispositivos de protección. La presencia de unidades generadoras altera el flujo radial inherente a un sistema de distribución y afecta al comportamiento del sistema de protección. Este trabajo presenta una introducción de los sistemas de protección de las redes de distribución y de la interconexión de unidades generadoras, describe la implantación de dispositivos de protección (interruptores, relés, reenganchadores, fusibles, seccionalizadores) en un programa tipo EMTP, y presenta algunos resultados obtenidos mediante simulación, cuyo principal objetivo es ilustrar el impacto que la generación distribuida basada en generadores síncronos puede tener sobre la coordinación de los distintos dispositivos de protección.Palabras clave: Distribución de energía eléctrica, modelación, simulación, generación distribuida, fusible, interruptor automático, relé de sobrecorriente, reenganchador, seccionalizador, protección de la conexión, funcionamiento en isla. ABSTRACT This paper presents the main features of a library of modules for representation of protective devices of distribution networks with distributed generation (DG).
