ICOEUR project results on improving observability and flexibility of large scale transmission systems

Interstate connection of power grids provides multiple advantages concerning operational security, integration of renewable energies as well as electricity trading. Based on these boundary conditions, the ICOEUR Project (supported by EU-FP7 and the Russian federal agency of science and innovation) studies smart technologies, to enhance the transmission capability, observability and security level of large scale transmission grids, such as a possible future interconnection of the European and Russian transmission systems. In this paper we present a selection of results of the ICOEUR project including case studies, such as an autonomous real-time coordination system for Power Flow Controlling devices. All case studies in the ICOEUR project are carried out on a common network model, which was developed by the project partners based on publicly available data. This network model consists of 545 nodes and includes a reduced dynamic model of an interconnected transmission system of European Network of Transmission System Operators for Electricity (ENTSO-E) and Integrated Power System/Unified Power System (IPS/UPS).
