3 THE UMBRELLA PROJECT FP 7 Project Umbrella 3

4 Challenges for TSOs in mainland Europe Uncertainties in transmission network operation due to increase of intermittent renewable energy sources (RES) and volumes of market based cross border flows and related physical flows Maximization of transportation possibilities New interconnections and devices for load flow control Development of coordinated grid security tools that take into account all technological measures for flexible power system operation Zonal structure of the European energy market with legal responsibilities of TSOs imposes increasingly complex requirements to the TSOs cooperation concerning quality and accuracy FP 7 Project Umbrella 4

5 Main Objectives of Umbrella Develop an innovative toolbox to support the decentralised grid security approach of 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 FP 7 Project Umbrella 5

8 Overview Main objective: Developing a set of methods describing the key developments/uncertainties influencing the future state of the electricity grid Considered uncertainties: Feed ins from renewable energy sources Load Intraday trading Power plant outages Main challenge: Most of processes are more or less easy to predict individually However, TSOs can only observe an aggregation of them Collection and use of data becomes difficult FP 7 Project Umbrella 8

13 WP4: RISK BASED ASSESSMENT FP 7 Project Umbrella 13

14 Risk based Security Assessment Goal: Maintaining power system security while facilitating integration of renewable energy and market operations! Risk = Probability Severity Approach: Risk based Security Assessment Utilize information about forecast uncertainties outage probabilities availability of corrective measures cascading events Severity: Expected loss Develop risk based measures of power system security for use in operational planning and market design. Probability Figure 1: Risk zones in operation based on different risk levels. [UCTE OH] FP 7 Project Umbrella 14

15 Developed Methods Optimal Power Flow (OPF) Monte Carlo based Risk Assessment Probabilistic Optimal Power Flow Assessment of overall risk level Uncertainty leads to a decrease in transfer capacity Incorporation of cascading risk Most of the risk arises from a few possible cascades Detailed assessment of critical situations Correlation Incorporating additional information can lead to better cost securitytrade off Forecast uncertainty (%) Correlation increases risk from forecast uncertainty FP 7 Project Umbrella 15
