EE-570: Power system restructuring and deregulation

This course presents different types and mechanisms of electricity markets. It addresses in particular their impacts on power/distribution systems operation and consequently the appropriate strategies capable to ensure a secure and reliable functioning. ...

Description

This lecture covers the concepts of ancillary services, capacity market, and the liberalization of the electricity market at RTE. It explains the generation, transmission, and distribution of electricity, the different markets, and the frequency control mechanisms. The instructor discusses the importance of system balancing, the role of different actors in the power system, and the challenges related to peak demand and grid security.

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.

Electricity market

In a broad sense, an electricity market is a system that facilitates the exchange of electricity-related goods and services. During more than a century of evolution of the electric power industry, the economics of the electricity markets had undergone enormous changes for reasons ranging from the technological advances on supply and demand sides to politics and ideology.

Peak demand

Peak demand on an electrical grid is simply the highest electrical power demand that has occurred over a specified time period (Gönen 2008). Peak demand is typically characterized as annual, daily or seasonal and has the unit of power. Peak demand, peak load or on-peak are terms used in energy demand management describing a period in which electrical power is expected to be provided for a sustained period at a significantly higher than average supply level. Peak demand fluctuations may occur on daily, monthly, seasonal and yearly cycles.

Ancillary services (electric power)

Ancillary services are the services necessary to support the transmission of electric power from generators to consumers given the obligations of control areas and transmission utilities within those control areas to maintain reliable operations of the interconnected transmission system. "Ancillary services are all services required by the transmission or distribution system operator to enable them to maintain the integrity and stability of the transmission or distribution system as well as the power quality".

Normal distribution

In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is The parameter is the mean or expectation of the distribution (and also its median and mode), while the parameter is its standard deviation. The variance of the distribution is . A random variable with a Gaussian distribution is said to be normally distributed, and is called a normal deviate.

Cauchy distribution

The Cauchy distribution, named after Augustin Cauchy, is a continuous probability distribution. It is also known, especially among physicists, as the Lorentz distribution (after Hendrik Lorentz), Cauchy–Lorentz distribution, Lorentz(ian) function, or Breit–Wigner distribution. The Cauchy distribution is the distribution of the x-intercept of a ray issuing from with a uniformly distributed angle. It is also the distribution of the ratio of two independent normally distributed random variables with mean zero.
