An online voltage stability margin (VSM) monitoring approach based on local regression and adaptive database is proposed. Considering the increasing variability and uncertainty of power system operation, this approach utilizes the locality of underlying pattern between VSM and reactive power reserve (RPR), and can adapt to the changing condition of system. LASSO is tailored to solve the local regression...
A novel approach for real-time monitoring of long-term voltage stability using local linear regression and adaptive training database is proposed in this paper. Comparing to previous methods, the proposed local predictive regression model could properly balance the simplicity/transparency and accuracy, and it is also adaptive to the changes of system and operating conditions. The approach is tested...
