Applied Mathematics for Restructured Electric Power Systems: Optimization, Control, and Computational Intelligence

Utilized arithmetic for Restructured electrical energy structures: Optimization, keep watch over, and Computational Intelligence involves chapters in accordance with paintings awarded at a countrywide technology beginning workshop equipped in November 2003. The topic of the workshop used to be using utilized arithmetic to resolve tough strength process difficulties.

Dynamics of Saturated Electric Machines

This publication is as a result of the author's paintings which was once initiated a couple of decade in the past and which, meanwhile, has led to his Ph. D. Thesis and a number of other technical papers. The booklet bargains with actual modeling of electrical machines in the course of temporary and regular states, a subject matter which has been frequently shunned within the literature.

Photovoltaik Engineering: Handbuch fur Planung, Entwicklung und Anwendung

In der Erstauflage stand die ingenieurmäßige Berechenbarkeit der Kennlinie des PV-Generators zur Lösung von Anpassungsproblemen im Vordergrund. In der zweiten Auflage wurde auf die Energie-Ertragsprognose von photovoltaischen Systemen zur Netzeinspeisung ausführlicher eingegangen und es wurden Methoden für Qualitätskontrolle und Ertragsgutachten vorgestellt.

Sample text

We hope that this ordering will serve best a reader intending to study all the articles. The first four articles (Chapters 2-5) are on power system stability. Sauer's article presents an introduction to power system reactive power stability, written in a fashion suitable for non-power engineers. , provides a method to find "weak" buses in a power system, which are vulnerable to voltage collapse. Such constraints can be accounted for dispatch and be considered for future reactive power support enhancement.

Therefore the sending-end VSMI should be used for ranking the voltage stability margin of the line. 9% as the operating point moves along the PV curves. 9%, which is considered to be very low. This indicates that there is no voltage stability margin available for this line to carry more power. This new approach was applied to the other parts of Entergy system for identifying the voltage stability weak locations. The simulation results show that the weak locations or critical transmission lines in the problem area were successfully identified using the proposed approach.

Similarly, Prabha Kundur says [9], "Voltage stability is the ability of a power system to maintain steady acceptable voltages at all buses in the system under normal operating conditions and after being subjected to a disturbance. " Prabha Kundur goes on to say, "The main factor causing instability is the inability of the power system to meet the demand for reactive power. '' These collective statements indicate how widely different the interpretation of the issue of "voltage collapse" can be.
