Abstract

An error-resilient state estimation is devised to calculate authentic states for microgrids equipped with hierarchical controls. New contributions include: 1) a state estimation incorporating droop control which helps mitigate estimation errors due to transient disturbance; 2) a secondary-control-empowered microgrid state estimation for leveraging power sharing and voltage regulation among DERs. Case studies demonstrate the robustness, efficiency and excellent convergence performance of the authentic state estimation approach.
