EE-370: Electric power systems

Ce cours décrit les composants d'un réseau électrique. Il explique le fonctionnement des réseaux électriques et leurs limites d'utilisation. Il introduit les outils de base permettant de les piloter. ...

Description

This lecture covers the calculation of active and reactive power transits in power networks, state estimation based on telemetry data, and the determination of active and reactive losses. It also discusses the modeling of short bonds, equivalent circuit diagrams, and the Newton-Raphson method for load flow analysis.

Instructor

Sidi-Rachid Cherkaoui

Rachid Cherkaoui received the M.S. degree in electrical engineering and the Ph.D. degree from Swiss Federal Institute of Technology (EPFL), Lausanne, in 1983 and 1992 respectively. From 1983 to 1987, he worked at Entreprises Electriques Fribourgeoises (Swiss electrical utility) developing a state estimator and security analysis tools for the HV transmission system of that company. From 1987 to 1992, he joined the power system laboratory of EPFL where he achieved his Ph.D. thesis in the field of optimal operation topologies for distribution systems. In this respect, he was the recipient of the ABB Swiss Award83. Since 1993, he is leading the research activities in the field of optimization and simulation techniques applied to electrical power and distribution systems. Presently his main research topics are electricity market deregulation, distributed generation and storage, and, power system vulnerability mitigation. He is senior member of IEEE, member of technical program committees of various conferences, member of CIGRE task forces C5-2, and IEEE Swiss Chapter officer since 2005. He serves regularly as reviewer for different journals and conferences. Dr. Cherkaoui is the author or co-author of more than 50 scientific publications.

Network analysis (electrical circuits)

In electrical engineering and electronics, a network is a collection of interconnected components. Network analysis is the process of finding the voltages across, and the currents through, all network components. There are many techniques for calculating these values; however, for the most part, the techniques assume linear components. Except where stated, the methods described in this article are applicable only to linear network analysis.

AC power

In an electric circuit, instantaneous power is the time rate of flow of energy past a given point of the circuit. In alternating current circuits, energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow. Its SI unit is the watt. The portion of instantaneous power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as instantaneous active power, and its time average is known as active power or real power.

Bachelor of Science

A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin scientiae baccalaureus) is a bachelor's degree awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855.

Bachelor's degree

A bachelor's degree (from Middle Latin baccalaureus) or baccalaureate (from Modern Latin baccalaureatus) is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to six years (depending on institution and academic discipline). The two most common bachelor's degrees are the Bachelor of Arts (BA) and the Bachelor of Science (BS or BSc).

Bachelor of Laws

Bachelor of Laws (Legum Baccalaureus; LL.B.) is an undergraduate law degree in the United Kingdom, Europe and most common law jurisdictions. It is awarded by universities in Europe, Australia, the People's Republic of China, Hong Kong S.A.R., Macau S.A.R., Malaysia, Bangladesh, India, Japan, Pakistan, Uganda, Kenya, Ghana, New Zealand, Nigeria, Singapore, South Africa, Botswana, Israel, Brazil, Tanzania, Zambia, and other jurisdictions. In the United States, the Bachelor of Laws was the primary law degree until the 1960s, when it was phased out in favour of the Juris Doctor.
