The interconnection of the power systems of the European Community (ENTSO-e) and of the Commonwealth of Independent States (IPS/UPS) arise several challenges for which regards the operation and the emergency control of a very geographically extended interconnected power system.
Recent international projects on the possibility ofinterconnection considered the option of synchronous interconnection through high voltage alternating current (HVAC) transmission lines.
Progresses in high voltage direct current (HVDC) technologies in the last years open the possibility of investigating other interconnection philosophies suchas purely asynchronous (i.e. using solely HVDC technologies), or hybrid (i.e. HVDC embedded in HVAC networks). ICOEUR, the joint project co-financed by the Russian Academy of Science and by the EU Commission has been set up to analyze possible solutions for some of these challenges withparticular focus on the operation and emergency control. This paper proposes new emergency control philosophies ofthe interconnection using the hybrid HVAC/HVDC option that seems, from the pointof view of emergency control, the most effective choice.
The experience of previous projects has shown thatthe creation of adequate test power network models of ENTSO-e - IPS/UPS is itself a challenging task mainly because of confidentiality of the static and dynamic data associated to the respective power systems. For the purpose of ICOEUR two test power network models have been created. These models are able to represent the main technical challenges of the ENTSO-e - IPS/UPS interconnected power networks. The first model is an extended test power network with more than 500-nodes and 1800 generators for 2010 time horizon, the second is a simplified test model with 98 nodes and 90-equivalent generators representing the 2020 time horizon. In addition to conventional HVDC model,the model of a voltage source converter (VSC) HVDC has been used in the test cases.
Among the various tasks performed in the frame ofICOEUR (Intelligent Coordination of Operation and emergency control of EU and Russian power grids) project, two of them are presented in this paper: the evaluation of topological interconnection concepts using the HVDC capability to improve the safety of the system and the examination of HVDC control efficiency using fuzzy methods. EUROSTAG has been chosen as the reference software for the project and has been extended to allow the modeling of advanced control strategies implemented as non-standard control.
