Sensitivities or partial derivatives of power-flow quantities have long been used for analysis and design of protection and control systems. Acknowledging these in the talk, we will shift our attention to analysis and computation of sensitivities of prevalent optimal power flow (OPF) formulations. Specifically, we will look at how OPF minimizers change with small perturbations in problem parameters, such as, the demand to be served, or transmission line parameters. We will formally answer when these sensitivities exist, and how numerically easy it can be to compute them, once the OPF has been solved. After pointing out how these sensitivities feature in some classical power-system design aspects, we will explore the rich space of applications where efficient sensitivity-computation tools can be a great asset. We will conclude the talk by discussing some contemporary efforts on the subject and promising future research directions.
