2010-04 Impact of the Integration of Wind and Solar Energy on the Operation of Power Systems: Realiability and Market Prices
November 10-12, 2010


   Electricity production from renewable energy sources (RES) is being promoted worldwide as a way to decrease CO2 and pollutant emissions. Nowadays special regime generation corresponds to cogeneration, renewable and biomass (photovoltaic solar power, wind power, geothermal, small hydro plants, and biomass and waste power plants) and urban and mining waste. Some of these RES are highly intermittent with sharp changes in power production and difficult predictability. When the ratio of electricity generated by this intermittent generation (IG) to the total system production is small the system operation is not substantially modified, it may be easily considered as a variation in the demand.
However, when the penetration of IG is high enough it may cause problems in the operation and should be taken explicitly into account in the operation models that need to be revisited for including it. In particular, nowadays wind power generation is the most important IG. Other types of IG include solar power generation.

The course will address the following topics:

· Fundamentals and concepts of the impact of IG in the electric systemoperation
· Simulation models for IG impact assessment
· Practical experiences of system operation with IG in the USA and some European countries

In addition the course includes a visit to Iberdrola’s or REE’s renewable control centre.


Prof. Andres Ramos (

He received the degree of Electrical Engineer, from Universidad Pontificia Comillas, Madrid, Spain in 1982 and the Ph.D. degree of Electrical Engineer from Universidad Politécnica de Madrid, Madrid, Spain in 1990. From 1982 to 1984 he was a research assistant at the Instituto Tecnológico para Postgraduados. Since 1984 he is at the Universidad Pontificia Comillas de Madrid. Currently, he is a Full Professor at the Industrial Engineering Department and at the Instituto de Investigación Tecnológica. Since 1999 he is Director of the Industrial Engineering Department. He was a visiting scholar at Stanford University, California, USA in 1991-92 academic year. Referee of international journals and conferences. Referee of the National Agency for Research Projects Evaluation. Member of several professional associations. His areas of interest include operations, planning and economy of electric energy systems, application of operations research to electric energy systems, and software development.


Prof. Javier Garcia Gonzalez (

Javier García was born in Salamanca in 1972. He obtained his Industrial Engineering degree, specialized in Electricity, from the Universidad Politécnica de Cataluña (UPC), Barcelona, Spain in 1996. After that, he joined the Instituto de Investigación Tecnológica (IIT), obtaining his PhD. degree in 2001. Currently he belongs to the research staff of the IIT and takes part in several research projects and consultancy developed for the electric sector.
