Wide Area Measurement Systems (WAMS) using phasor measurement unit (PMU) demonstrate the great potential in monitoring and analyzing power systems. Synchrophasor applications, such as system monitoring, wide-area controls, linear state estimation, and advanced training simulator, are developed to utilize valuable information from synchronized phasor data. However, there are challenges for both power...
The Multi-Area Thévenin Equivalent algorithm (MATE) partitions a network into a number of subnetworks connected by links. The solution proceeds in two stages: first the subnetworks are solved independently, with the links open, and then the system formed by the links is solved with the subnetworks represented by their Thévenin equivalents as seen from the link nodes. In this paper, an overview of...
Based on entropy weight-based gray relational method, a new outcomes severity model of security assessment is put forward. This model mainly reflects severity degree and fully shows the influence degree of different factors affecting severity. And risk factor is introduced to assess the system security after contingencies, computed by the product of contingency probability and outcome severity degree...
