Über dieses Buch

The market liberalization is expected to affect drastically the operation of power systems, which under economical pressure and increasing amount of transactions are being operated much closer to their limits than previously. These changes put the system operators faced with rather different and much more problematic scenarios than in the past. They have now to calculate available transfer capabilities and manage congestion problems in a near on­ line environment, while operating the transmission system under extremely stressed conditions. This requires highly reliable and efficient software aids, which today are non-existent, or not yet in use. One of the most problematic issues, very much needed but not yet en­ countered today, is on-line dynamic security assessment and control, enabling the power system to withstand unexpected contingencies without experienc­ ing voltage or transient instabilities. This monograph is devoted to a unified approach to transient stability assessment and control, called SIngle Machine Equivalent (S1ME).

Chapter 1. Background
Abstract
The objectives of this Chapter are:
  • to define the transient stability problem in the realm of power system security, its operating modes, application contexts and corresponding needs (Section 2);
  • to elaborate on transient stability phenomena and modeling (Section 3) and discuss about main strengths and weaknesses of the conventional time-domain approach (Section 4);
  • to review the“conventional”direct approaches, examine whether and to which extent they are able to cover (some of) the needs in transient stability studies, and introduce the spirit of the method developed in this monograph (Section 5);
  • to give a summary of the class of automatic learning methods, so as to subsequently enable comparisons between them and the method developed in this monograph (Section 6);
  • to describe the scope and overall organization of this monograph (Section 7).

Chapter 2. Introduction to SIME
Abstract
The objectives of this Chapter are:
  • to trace the origins of SIME and state its principle (Section 1)
  • to define the rules of OMIB’s automatic identification and set its general formulation (Section 2)
  • to scrutinize the derivation of stability margins and related issues (Section 3)
  • to illustrate the developments on a simple example easily tractable by the reader (Section 4), with the exception of phenomena specific to large-scale systems (Section 5)
  • to give a flavor of the way the techniques developed in this chapter will be used in the remainder of the monograph (Section 6)
  • to point out main differences between preventive and emergency SIME (Section 7).

Chapter 3. Sensitivity Analysis
Abstract
Chapter 2 has dealt with two major achievements of SIME: calculation of stability margins and identification of critical machines; stability margins are at the very core of SIME-based sensitivity analysis.

Chapter 4. Preventive Analysis and Control
Abstract
Chapter 2 has dealt with calculation of margins and identification of critical machines. Chapter 3 has used them to derive sensitivity analysis techniques. This chapter shows that stability margins, critical machines and sensitivity analysis are the necessary and sufficient ingredients for conducting any type of transient stability study including analysis, filtering, ranking, assessment and stabilization of contingencies. More precisely, the objectives of Chapter 4 are:

Chapter 5. Integrated TSA&C Software
Abstract
In this chapter, techniques developed in Chapter 4 are organized to set up a unified TSA&C software aiming to cover an as large as possible spectrum of preventive security issues.
Mania Pavella, Damien Ernst, Daniel Ruiz-Vega
Chapter 6. Closed-Loop Emergency Control
Abstract
The previous chapters have addressed preventive TSA&C issues and developed appropriate techniques. In particular, Chapters 4 and 5 focused on preventive control aiming to design pre-contingency remedial actions able to stabilize harmful contingencies, should they occur. The actions concerned generation shifting.

Chapter 7. Retrospect and Prospect
Abstract
This monograph has been devoted to a hybrid temporal-direct methodology, tailor-made for power systems transient stability assessment and control
