This work deals with a new formulation for the Direct Current Optimal Power Flow (DCOPF) including the corrective actions related to the phase shifting transformers. The formulation is based on the outage of generators and/or branches modelled as fictitious injections of active power. The inclusion of the sensitivities of the phase shifting...

This work deals with a new formulation for the direct current corrective optimal power flow. The formulation is based on the outage of generators and/or branches modelled as fictitious injections of active power. By including that fictitious injections in the optimization problem, the injections are adjusted to the post-contingency state as a...

A new procedure focused on reliability analysis of subtransmission systems supported by the state enumeration technique is presented. This new methodology is conducted in three stages. First, a classical state enumeration reliability assessment is performed for the branch-node model of a subtransmission system, assuming that substations are...

En esta comunicación se describe una nueva metodología aplicable al cálculo en tiempo real de los índices de calidad de suministros en redes de transporte y de distribución. Con el método de análisis que se propone, las subestaciones son modeladas, inicialmente, como un simple nudo eléctrico y bajo ese supuesto se realiza la evaluación del...

It is well known that topology changes in a power system strongly influences the results of reliability assessment studies. Besides, it is obvious that the topology of an external system also affect the reliability of the internal system through changes on the power flows within the rest of the system, and hence, through changes on the tie...

This paper proposes a new methodology for shortterm (24 hours) reliability assessment of transmission and distribution networks, including detailed substations models. Substations are first considered as single electrical nodes to evaluate the reliability of delivery nodes. If nodes (substations) with a high LOLP (Loss of Load Probability) are...

In this paper, educational software for the reliability assessment of high/medium-voltage (HV/MV) substations and distribution feeders is presented. It is a useful tool for learning the utility of reliability indices of the HV/MV substations and their distribution feeders, and their influence on the electrical power system operation. By means...

El panorama socioeconómico actual ha propiciado un gran auge en el uso de energías renovables. El importante crecimiento de estas energías, también se debe en gran medida a la preocupación social por los impactos medioambientales de las denominadas energías no renovables. Hay casos en los que se tiene que acometer el suministro de energía...

This paper describes a laboratory-based teaching proposal for the understanding of three-phase circuits at the undergraduate level of engineering degrees. The practical content of the proposed activities is oriented towards easing the students' understanding of the main concepts involved in three-phase circuits. The subject of three-phase...

The philosophy of safety at work is one of the bases for the operation of electrical installations, with particular relevance in the manoeuvres in electrical substations. The curriculum for Electrical Engineering students should include such knowledge. This article presents an educational tool currently in use, which has demonstrated its full...
