A Method for Automatic Discovery of Transmission Sections with Critical Branches Taken into Consideration
摘要
Abstract
In large scale power systems, the specially defined transmission section could be used to measure the security levels of actual system operating states. However, existing approaches for the automatic discovery of a transmission section has not properly considered the critical branch with the minimum security margin. Hence the accuracy of the security level evaluation cannot be guaranteed. Given this background, a new method for automatic discovery of transmission sections with the critical branch taken into account, is developed for assisting system operators to find more reliable and accurate control strategy. First, a set of transmission sections is obtained by employing the network topology and real-time power flow. Next, a repeated power flow based approach is used to evaluate the maximum transmission capability of each transmission section, while the critical branch is identified. Then, the critical branches are included in a transmission section to be served as the monitoring objects, and a control strategy is obtained for ensuring the security of the power system concerned. Finally, the effectiveness of the proposed method is demonstrated by Guangdong provincial power system.关键词
