Security and Congestion Management Tool for the Use in Extended Transmission Systems

Abstract

In a treatment of security and congestion management large interconnections consisting of networks operated by independent organizations are considered. The security of the proper network surrounded by several neighbors is in the focus. The analytical steps for measuring, estimation, boundary matching and load flow calculation including an appropriate tool are described. Special features for the estimation, matching of neighboring networks and modeling of components are given. The highlights of the performance and the precision of the results are underlined, supplemented by the way in which results in a user oriented manner are presented. The tool is implemented in a control center of a member of the UCTE network.
