Abstract

Due to an increase in converter-interfaced renewable generation, power networks are becoming increasingly reliant on power converters, which have contrasting dynamical behaviour to rotating machines with large inertia. This results in new control challenges for the power grid. We focus in this paper on decentralized conditions that can provide stability guarantees for networks with grid-forming converters. In particular, we consider the dynamics of various grid-forming converter configurations and controllers, and show how these can be designed to satisfy an appropriately formulated local passivity condition that provides stability guarantees for the network. Simulations confirm that designs satisfying this property improve the stability and dynamic response of the power network.
