We prove that virtual friction can stabilize a power grid containing several synchronous machines (VSMs), connecting line impedances and loads. Virtual is torque added to the swing equation of each VSM, proportional deviation its frequency from overall center inertia (COI) frequency. Our analysis based on network reduced system (NRPS) model. support our results with simulations for two-area fou...
