Smart fault handling in medium voltage distribution grids
This paper presents first results from a pilot project on using fault indicators and self-healing in medium voltage distribution grids. Directional earth-fault indicators were chosen and deployed in real environments to test their functionalities and quantify their benefits for efficient grid operat...
Enhanced method for reliability of supply assessment - an integrated approach
A comprehensive analysis of reliability of electricity supply to end users requires a unique set of models, methods and tools. Of special significance are long term power market models for predicting future operating states (generation and load patterns) and more detailed network simulation models f...
Contingency screening starting from probabilistic models of hazards and component vulnerabilities
The need to analyze high-impact low-probability events on power systems, due to natural and man-related threats calls for comprehensive approaches to security assessment, which exploit the concept of risk. The paper describes a probabilistic approach and a tool, developed in the EU research project ...
On Improving Data and Models on Corrective Control Failures for Use in Probabilistic Reliability Management
Wind dependent failure rates for overhead transmission lines using reanalysis data and a Bayesian updating scheme
The main task of this paper is to calculate wind dependent failure rates for overhead transmission lines using reanalysis data and a Bayesian updating scheme. The availability of finely meshed hourly reanalysis time series for wind speed allows us to construct individual fragility curves for each tr...
Probabilistic Risk-Based Security Assessment of Power Systems Considering Incumbent Threats and Uncertainties
In-depth security analyses of power systems (PSs) require to consider the vulnerabilities to natural and human-related threats, which may cause multiple dependent contingencies. On the other hand, such events often lead to high impact on the system, so that decision-making aimed to enhance security ...
