In this paper, we propose a hierarchical transactive control architecture that combines market transactions at the higher levels with inter-area and unit-level control at the lower levels. A model of the overall grid is introduced, with dynamics at primary, secondary, and tertiary levels. With a goal of ensuring frequency regulation using optimal allocation of resources in the presence of uncertainties...
The paper presents analysis of the torsional torques of a turbine generator rotor system in a meshed AC network with monopolar HVDC link following symmetrical and asymmetrical faults. The emphasis of the work is on establishing the influence of uncertainties in the mechanical parameters of turbine-generator shaft system on maximum torsional torques. Three loading conditions of turbine generator are...
