1 Innovative tools for the future coordinated and stable operation of the pan-european electricity transmission system Dr. Wilhelm Winter, TenneT TSO GmbH, Coordinator Research Project umbrella Open Workshop 21 st June 2012,, ENTSO-E premises, Avenue de Cortenbergh 100, Brussels, Belgium

2 ENERGY Innovative tools for the future coordinated and stable operation of the pan-european electricity transmission system Call Identifier Funding Scheme FP7-ENERGY Collaborative project Full Title: Toolbox for Common Forecasting, Risk Assessment, and Operational Optimization in Grid Security Cooperation of Transmission System Operators (TSOs) 2

3 Develop a dedicated innovative toolbox to support the decentralised grid security approach of transmission system operators (TSOs). This toolbox shall include simulation of uncertainties due to market activities and renewables on different time scales optimisation of corrective actions in reaction to simulated risks on different time scales according to total costs and transmission capacities. development of risk based assessment concepts for anticipated system states with and without corrective actions Demonstrate the enhancement of existing and running procedures by utilisation of the developed toolbox Provide a scientifically sound basis to support common TSO decisions. 3

6 Challenges reported by TSOs concerning system operation with a significant contribution from RES relate to: o Coordinating the operation of flow controlling devices across Europe. o Coordinating system arrangements to adjust power flows in the event of faults and other events. o Developing and using dynamic equipment ratings reflecting ambient conditions, loading and conductor temperatures. o Shared intelligence on developing generation and load conditions (including wind forecasts). o Suitable monitoring and control facilities. o Procedures for using enhanced operational measures so that maximum benefit is achieved across each region. 6

7 Identified Operational Risks o Imbalance o Frequency instability (frequency response) o Voltage instability (Voltage control options and o short circuit Power ratio) o Overall Stability due to high transit flows in emergency cases - Risks leading to a lack of adequacy - Risks leading to a lack of system security - Financial risks Mitigation Measures o Urgent need to reinforce the transmission system o Harmonized and sustainable requirements o Emergency Control Actions (ECA) o Coordination among TSOs o Funding arrangements for network strengthening 7

8 Expected future challenges Increasing uncertainties due to growing share of electricity generation from intermittent renewable energy sources as well as increasing market-based cross border flows Enhance grid capability and grid flexibility New planned interconnections including new technologies, devices for power flow control and FACTS for system services will offer new possibilities in network operation Better system coordination and cooperation by using common tools Further developments of common grid security tools are therefore one of the major challenges European TSOs will face in the midterm. Coping with these challenging system security research issues the toolbox to be developed will enable TSOs to ensure secure grid operation also in future electricity networks with high penetration of intermittent renewables. 8

TSC delivers input which is helpful for TSOs and for all existing security initiatives (centralised, decentralized...) TSC is compatible with all (TSO-internal) organisational forms TSC is extendable at will to other TSOs (also in other synchronous areas) 11
