Remote sensing for active online parameter estimation in digital power grids

Research Project, 2019 – 2020

The aim of this project is to exploit the opportunities that an extensive layer of communications will bring in the future power-electronic dominated power system. In particular, the project focus is on using local and remote measurements for system parameter estimation to enhance the observability of the power system. The acquired measurement information will be used to estimate the frequency-dependent impedance of the power system seen from a specific connection point. Several system conditions, from steady-state to fast dynamics due to large disturbances, i.e., short-circuit faults, will be considered and investigated. Different estimation methods will be analyzed and evaluated. The final goal of the project is to provide a fast-online measurement of the power system impedance at a specific connection point for a wide-frequency range, to be later used for robust control of grid-connected converters.
