A decentralized power grid control using a Swarm-Grid approach is proposed. It includes an exchange of measured data between components and a grid state estimation. Here, methods for calculating the current grid state and for generating pseudo measurements in case of non-convergence of the algorithm are proposed. Additionally, worst-case assumptions are presented which help to achieve reasonable estimates of the unknown grid voltages and currents used for the decentralized grid control. Finally the impact of unknown phase information is derived.
