Popis: | Simple performance indices for detecting and predicting stability problems such as the voltage collapse are useful analysis tools for planning and operating engineers in power utilities. We propose a fast guided continuation method to predict or compute a reliable performance index that takes proper care of limits of reactive power resources. The main feature is the novel combination of a Q limits index and a performance index to achieve computational efficieny and index reliability. Numerical experiments using standard IEEE 9-, 14-, 30-, 57-, 118-, 300-bus systems and a NGC 40-bus system show that the proposed method can predict or compute the voltage collapse point much faster than the standard continuation. |
