Abstract [en]

Modern society is largely dependent on electricity supply and Transmission System Operators (TSOs)have to ensure the reliability of supply in situations that are increasingly difficult to manage due tohigher consumption levels and variability of new intermittent energy sources. In order to ensure thesystem’s safety, voltage stability is a matter of prime importance and is dealt with for different timeframes.Ahead, new reactive power compensation means are installed to prevent voltage collapse. Then, if avoltage collapse gets under way, ultimate mitigation measures have to be taken: Load Tap Changershave to be blocked because of their negative action in critical situations.The first objective of this Master’s Thesis consists on the development of a method to optimize theLTC blocking parameters through dynamic simulation. Then, this method has been applied in fourregions of the French grid and the results have been implemented in the end of the year 2012.The second objective of this Master’s Thesis consists of the development of a method to assess theeconomic gain thanks to the investment in reactive power compensation means for the French TSO.
