Summary

The talk addresses the challenges of integrating variable energy resources (VERs) like wind and solar into the power grid, which introduce significant uncertainty due to weather dependence. The speaker, Sara Eftekharnejad, discusses the shift from traditional predictable centralized generation to a more uncertain grid with distributed and inverter-based resources. She highlights the reduction in system inertia and the need for accurate forecasting and predictive models to maintain reliability. The presentation covers the interdependency between generation uncertainty and grid failures, emphasizing the need for holistic modeling. She presents research on developing robust predictive models for VER generation and grid failure modes, using real data from upstate New York to show the inadequacy of traditional statistical models. The talk concludes with the importance of understanding acceptable levels of uncertainty and the need for adaptive models to handle abrupt changes in generation.
