摘要
Abstract
Based on traditional continuation power flow a faster and more accurate static voltage stability analysis method, called improved continuation power flow method, is proposed. In the proposed algorithm, the Newton quadric interpolation method is used for the prediction; the improved Newton-Raphson method is used to modify the prediction results; considering the limit of reactive power output of generator, the PQ node conversion is applied to generator nodes. The proposed method is flexible, accurate, easy to understand and can reflect actual operation condition of generator more accurately than previous continuation power flow method. In the proposed method there are lesser corrections to be modified and lesser iterations. Taking IEEE 9-bus system as the background, the proposed method is compared with traditional algorithm under the conditions of considering and not considering reactive power limit respectively, and comparison result shows that the proposed method is better than traditional method in both iterations and iteration time.关键词
