For a coordination of the power system operation in Europe

摘要

The operational safety of electric systems is regularly highlighted by TSOs as an essential consideration to be taken into account to facilitate as much as possible the development and the effectiveness of the European electricity markets.However, the efforts TSOs have already done and are in the process of doing as regards market access have to be accompanied by enhanced coordination between TSOs to guarantee the operational safety of the interconnected system.The weaknesses of inter-TSO coordination are well known: no global, region-wide visibility, segmented security analyses, different security analysis models hampering joint security analyses, the lack of global assessment of coordinated remedial actions, and so on. As a consequence there is no quick, coordinated action to deal with congestions caused by unexpected events affecting the power system. This fragmented vision of each TSO to its own grid appears to be one of the main root causes of recent disturbances in Europe (September 2003 and November 2006).In the same time, the operational environment is changing and European TSOs have to combine successfully 3 major stakes that are:the operational safety of the power system,the insertion of a large part of renewable generation, specially wind generation,the development of the electricity market.To provide relevant responses to two main stakes mentioned above, some TSOs support the idea to improve the coordination with a much more ambitious response, to meet the need for improved security of supply and to ensure credibility for their approach.The organisational model proposed to satisfy operational security concerns is based on the creation of a dedicated coordination centre, bringing together the technical resources and skills.
