CONGESTIONS IN ELECTRICITY TRANSMISSION SYSTEM CASE STUDY

Abstract

This paper aims to present the congestion problem within the power transmission systems and cross-border transmission networks. The worldwide congestion management applied methods are the following ones: limited access to transmission network, priority list (first come, first served), pro-rata rationing, explicit auctions, implicit auctions, market splitting, redispatching and cross-border co-ordinated redispatching. The case study is represented by a real, large scale power system, operated by Timisoara Transmission Subsidiary of C.N.T.E.E. Transelectrica.
