    Abstract: A fault-tolerant method and system of controlling electromechanical oscillations in a power system. The system of controlling comprises at least one phasor measurement unit (58, 60, 62, 64) obtaining phasor data signals including oscillating mode signals, at least one wide area control system (66) receiving the phasor data signals from the phasor measurement unit, and at least one actuating device (80, 82, 84) for receiving a control signal from the wide area control system. Specifically, the wide area control system performs the fault tolerant control method of the present invention, wherein information about each critical oscillatory mode of an oscillation is extracted from a model, selected residues for each critical oscillatory mode are grouped together, and a partial damping controller is designed for each selected critical oscillatory mode using residues from the same group. A multivariate damping controller is produced and applied to one or more actuating devices in the power system to control electromechanical oscillations.

    Abstract: The present invention is concerned with a master control system layer for a Voltage Source Converter (VSC) based Multi-Terminal High Voltage Direct Current (MTDC) system. The invention is applicable to general topologies of the MTDC grid, including meshed topologies and isolated islands, and its benefits become specifically apparent in MTDC systems with five or more terminals where management of all possible different operating condition will require unacceptable engineering efforts if only simple feedback control loops are used. The invention includes mathematical optimization procedures to determine, in real-time and based on actual operating conditions, controller settings that minimize a cost criterion or optimize any other objective function. Controller settings include set-points or reference values as well as controller parameters such as droop constants or gains. Furthermore, it introduces model predictive control to include predictions of the effect of control actions on the system state evolution and predictions of future operating conditions in the optimization procedure.

    Abstract: The invention provides improved control of a power transmission system having a first group of measurement units (10, 12, 14) in a first geographical area (A_1) providing a first set of phasors and a second group of measurement units (16, 18) in a second geographical area (A_2) providing a second set of phasors, where the phasors in the sets are generated at the same instant in time. In this system the power control device (32) includes a phasor aligning unit (30) that time aligns the first and second sets of phasors and a control unit (33) that compares each set of phasors with a corresponding phasor number threshold, determines that a first control condition is fulfilled if each phasor number threshold has been exceeded and enables the provision of a common signal if the first control condition is fulfilled. The common signal is based on the obtained phasors in the first and second sets.
