3.1 Introduction

Current developments in the power system put increasing stresses on the transmission network. The transition towards a renewable energy supply, the integration of large-scale renewable energy sources (RES) and the liberalisation of the electricity market are some of the challenges for the transmission network. At the same time, the lowest cost of an ageing transmission network is strived for. To prevent large blackouts, reliability analysis and reliability management are of the utmost importance. While deterministic approaches and criteria have been used effectively in the past, probabilistic methods will be increasingly applied in the future as these provide more insight into the reliability of the transmission network.

This chapter describes how probabilistic reliability analysis is used to study the reliability of large transmission networks. We discuss how probabilistic reliability analysis is related to deterministic ...
