A- Background and objectives
The European Transmission Network (ETN) has been evolving significantly in the ways that network operators work and cooperate with each other, in particularly by setting up common operating procedures and tools such as network simulation tools for coordinated training purposes. In the domain of power system state estimation and transmission network time simulation, very few innovations have emerged over the past decade (2000-2010) in Europe. Breakthroughs are therefore expected in power system simulation along four directions to serve the ETN: state estimation, optimization algorithms, time domain simulation and power system component modelling.
The PEGASE Project articles project removes several algorithmic barriers related to the monitoring, simulation and optimization of very large power systems, therefore paving the way for improved network operation and system security. The four-year R&D activities ending June 2012 have developed new powerful algorithms and full-scale prototypes able to model the whole ETN for state estimation, dynamic security analysis, operation optimization and real-time simulation and training tools for operators. The validation steps of such network simulation tools used realistic data representative of the ETN, without structural simplifications but not the real set of data of this highly complex network. The project objective was indeed only to test the adequacy and performances of the software tool prototypes, by the way identifying but not solving future data management issues (in particular for real-time data).
The project achievements can be summarized as follows:
The PEGASE project developed a new generation of ground-breaking algorithms for state estimation, dynamic simulation and optimization of the Pan-European power system. The developed algorithms are suitable for dealing with new challenges in all aspects of network operation, especially with regards to very large power systems incorporating a range of new power technologies.
The PEGASE consortium has selected, combined and implemented the developed algorithms into full scale prototypes of power system applications. The soundness and efficiency of developed solutions are demonstrated by running large-scale demonstrations , through test cases representative of the ETN. The tests were carried out by the TSOs involved in the project, thus ensuring the compliance between the actual needs of the profession and the developed solutions. The PEGASE project has proved therefore that the existence of adequate tools is no longer a technical barrier for moving towards an integrated Pan-European power system operation that will ultimately allow operating the ETN closer to its physical limits. This added network flexibility in operation strongly supports massive renewable energy integration into the electricity market in Europe.
Since the seven prototypes have been tested by potential end users, the specifications of the future industrial solutions can be readily delivered, reducing the financial risk of commercialization of the following solutions (links towards knowledge articles):
