The primary objective of this study is to determine if there are significant trends in the oscillatory behaviors with respect to the evolution of generation mix and consumer participation in the North American power grids. The initial focus is on the Western Interconnection followed by extension to the Eastern Interconnection.
The primary motivation for the study is the currently unknown nature of the potential impact of the on-going power system transition on system modal properties and wide-area oscillatory behavior. This study will review the past events and will model and evaluate the performance of the future grid. Such a trending analysis has not been performed comprehensively, but the outcomes of such an analysis are of great value for managing and planning the current and future grids.
A secondary objective is to adapt and develop a set of tools and procedures which can be used for future oscillation assessment and analysis.
