Distributed Power System Security Analysis

Serial processing of one computer at the system control center does not easily meet the needs of power system real-time monitoring and security analysis. In this chapter we propose an online distributed external equivalent method, and study the distributed power system security analysis method based on this equivalency method. The online distributed external equivalent is more accurate than the traditional Ward method, which is based on a pre-chosen base case. The performance index computation can be executed in a distributed manner for a more accurate and faster solution.
