Recent trends of deregulation and expansion in power systems have greatly increased their stress levels and hence, ensuring their safety has become a critical challenge. In the event of disturbances, detecting the groups of coherent generators is important to study the characteristics of the system. We propose VANTAGE, a Lyapunov exponents based technique for identification of coherent groups of generators...
Very fast on-line computational capability to predict mid-term dynamic system response to disturbances and identify corrective actions is an important attribute of high-speed extended term (HSET) time domain simulation (TDS). Focusing on the development of computational speed, this paper propose a parallel strategy intended for deployment on the super computer, Blue Gene/L, to simulate the power system...
A linear optimization problem is formulated to enable the independent system operator (ISO) to make least cost decisions for purchasing ancillary services. The ISO is responsible for adjusting the schedules resulting from the market clearing process to eliminate congestion [M. Gibescu and C.C. Liu, 1998]. Both the sequential and the simultaneous DC formulations for congestion management and ancillary...
Multiple sequence alignment is an important task in bioinformatics which forms the basis of many other tasks like protein structure prediction, protein function prediction and phylogenetic analysis. An optimal multiple sequence alignment for a given set of sequences is difficult to determine by standard dynamic programming algorithms because of impractically high computational complexity. Therefore,...
