Sammanfattning

We investigate local convergence of identical DC/AC converters interconnected via identical resistive and inductive lines towards a synchronous equilibrium manifold. We exploit the symmetry of the resulting vector field and develop a Lyapunov-based framework, in which we measure the distance of the solutions of the nonlinear power system model to the equilibrium manifold by analyzing the evolution of their tangent vectors. We derive sufficient and fully decentralized conditions to characterize the equilibria of interest, as well as their region of contraction. We provide ways to satisfy these conditions and initialize each converter on the contraction region. We illustrate our results based on numerical simulations of a two-converter benchmark.
