Evaluation of Operational Risk in Power Substations and Its Rational Reduction on the Basis of Multicriteria Allocating Resources

The present work aimed at improving the quality of operational risk estimation for power substations and increasing the efficiency in its reduction using models and methods of multicriteria decision-making. The application of the proposed methodology allows one to assess, compare, prioritize, and/or...
