Wide deployment of sensing and actuation capabilities in the electric power grid, along with changing dynamical characteristics, are necessitating analysis of power-system swing dynamics from an input-output perspective. In this article, the input-output properties of the swing dynamics, including the finite and infinite zeros, are characterized from a dynamical-networks perspective. Specifically,...
Power system contingency screening is aimed at detecting potential threats, such as tripped transmission lines, to support secure operation of power systems. The growing penetration of intermittent-renewable resources into the power system challenges the traditional paradigm of contingency screening. One particular concern is that different renewable-generation profiles may lead to changing severe...
