This paper provides a summary of the state of electric power engineering education through descriptions of professional society activities, Internet resources, and results of a worldwide survey conducted in March 2003. Index Terms--Engineering education, Internet resources.

This letter describes electric power quality as an important component of electric power engineering education. Because power quality engineering relies on signal processing concepts as well as applied power engineering, students in both undergraduate and graduate educational programs find the topics cross-disciplinary, practical, and motivational. Index Terms--Power distribution, power engineering education, power quality.

A manpower shortage is forecasted for qualified electric power engineers as the number of retirees exceeds new hires. This letter discusses the opportunities and challenges of the distant e-learning (e-training) for electric power engineers and presents the progress of two programs established in North America. The experience is augmented by observations from a sampling at other universities. E-learning is suggested as a measure for enhancing power engineering professional training. Index Terms--Continuing education, e-learning, power engineering education.

Controlled islanding refers to the controlled separation of an interconnected power system into electrically isolated regions. The objective of this paper is to develop adaptive controlled islanding as a component of an emergency power system control strategy. There are two primary aspects of controlled islanding: 1) where to island and 2) when to island? Assisted by a decision tree (DT) approach, this paper seeks to address the ‘when to island’ aspect. A decision tree based tool is proposed to recognize conditions existing in the system that warrant controlled islanding. A 29-generator, 179-bus system is employed to demonstrate the tool. Simulation data are used to train DTs, and the online performance of DTs is then evaluated as part of a controlled islanding strategy. [ABSTRACT FROM AUTHOR]

Slow coherency-based generator grouping in power systems is primarily dependent on the participation of generators in the slow modes. In the literature, generator coherency has been typically obtained at a specific operating point. This paper presents a new approach using the continuation method to trace the loci of the coherency indices of the slow modes in the system with respect to variation in system conditions to obtain the updated coherency information between generators. The approach has been applied to a 10-generator 39-bus New England system, and a 29-generator 179-bus model of the WECC system and the impact of load variation on generator coherency indices has been investigated.

This letter contains the analysis of the increase of fault current due to the installation of distributed resources or merchant plants. An index called the average change of fault (ACF) current is proposed. The ACF can be applied to indicate the contribution of the increase of fault current and to allocate the responsibility of system upgrades among the owners of distributed resources.

This letter describes multiobjective optimization as a topic to be included in an undergraduate electric power engineering curriculum. [ABSTRACT FROM AUTHOR]

In this letter, modification to an existing formula for determining the contribution of generation companies to unscheduled flows in electric power networks is presented. The enhanced form of the contribution factor formula provides two options for calculating the contribution of generation companies based on the magnitudes of all the minor loop flows and the largest minor loop flow induced, respectively. A numerical example for a modified IEEE 30-bus test system is provided. [ABSTRACT FROM AUTHOR]

This letter explains the duality between the generation unit commitment problem and the distribution restoration problem. The importance of this observation is that extensive analysis and prototyping of efficient solutions to the unit commitment problem can be applied to the distribution restoration problem.
