Load Sensitivity Studies and Contingency Analysis in Power Systems


Abstract The past decades have seen a significant shift in the expectations and requirements re-lated to power system analysis tools. Investigations into major power grid disturbances have suggested the need for more comprehensive assessment methods. Accordingly, sig-nificant research in recent years has focused on the development of better power system models and efficient techniques for analyzing power system operability. The work done in this report focusses on two such topics

1. Analysis of load model parameter uncertainty and sensitivity based pa-rameter estimation for power system studies

2. A systematic approach to n-1-1 analysis for power system security as-sessment

To assess the effect of load model parameter uncertainty, a trajectory se... (more)
