Abstract
Methods for damping oscillations in a high voltage power grid, including power distribution and supply systems by distributing a plurality of voltage/impedance injection modules to inject voltages/impedances onto high voltage power transmission lines of the power grid, sensing power oscillations on the high voltage transmission lines, extracting the dominant oscillatory mode or modes of sensed power oscillations on the high voltage transmission lines, and injecting voltages/impedances responsive to at least the most dominant oscillatory mode onto the respective high voltage transmission lines to counteract the respective oscillations.
