摘要： 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.

摘要： 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 multivariable damping controller is produced and applied to one or more actuating devices in the power system to control electromechanical oscillations.

摘要： The present invention is concerned with the computation of power system sensitivities from power flow parameters and control parameters of a Power Flow Control Device (PFC). To this end, control parameter variations are applied to or generated by a PFC (20), and comprise variations in a control input u , a control effort e (injected series voltage, inserted series reactance), or a control effect q (power flow, active power transfer, phase-shift, current). A power flow response measuring unit (40) measures a variation of a power flow response such as current, active or apparent power, in a way sufficiently synchronized with the control parameter variation to allow establishing an unambiguous causal relationship or correspondence in the form of a power system sensitivity. The latter may be on-line adapted to continuously reflect an updated aspect of the power system behaviour, and thus enable an improved, fast and reliable power flow control in power systems comprising a meshed power network with two parallel flow paths or corridors connecting two areas or sub-systems.
