Applied Mathematics for Restructured Electric Power Systems: by Joe H. Chow, Felix F. Wu, James A. Momoh

By Joe H. Chow, Felix F. Wu, James A. Momoh

Applied arithmetic for Restructured electrical strength structures: Optimization, regulate, and Computational Intelligence comprises chapters in response to paintings provided at a countrywide technological know-how starting place workshop geared up in November 2003. The topic of the workshop was once using utilized arithmetic to resolve not easy strength approach difficulties. The parts integrated keep watch over, optimization, and computational intelligence. as well as the introductory bankruptcy, this ebook comprises 12 chapters written through popular specialists of their revered fields. every one bankruptcy follows a three-part layout: (1) an outline of an incredible energy method challenge or difficulties, (2) the present perform and/or specific examine methods, and (3) destiny examine instructions. jointly, the technical components mentioned are voltage and oscillatory balance, strength approach safety margins, hierarchical and decentralized regulate, balance tracking, embedded optimization, neural community regulate with adaptive critic structure, keep watch over tuning utilizing genetic algorithms, and cargo forecasting and part prediction.

This quantity is meant for energy structures researchers and execs charged with fixing electrical and tool method problems.

VSMI at the nose of the P V curve for Amite South Region. 24 3 NAPOLEON MARKET ST. 23 7 GYPSY UNIV. 1 are found to be the major tie lines in the Amite South area. The VSMI index for these lines is observed to be below lo%, which indicates that they are weak lines. 2 The Gypsy to South Norco 230kV line, which carries the most power into this area, was found to have the lowest VSMI index (less than 1%). This indicates that the line is heavily loaded and has very low voltage stability margin. 1 are found to be consistent with the P V curve analysis.

2 PV curves are not very useful in identifying the weak buses in the system. 3 PV curve analysis is only valid for a particular scenario. If the scenario changes, a new set of PV curves needs to be reproduced. This process can be very time consuming. In this chapter, a new approach for studying voltage stability problem has been developed. The relationship of voltage stability and angle difference between sending- and receiving-end buses is described, and the concept of Voltage Stability Margin Index (VSMI) is introduced.
