    摘要: A method and system are disclosed for managing congestion in an electrical transmission network. The electrical transmission network includes Power Flow Control Devices (PFDs) that adjust the transmission capability of the electrical transmission network. The method includes determination of a reference generation schedule followed by setting up of an objective function based on the reference generation schedule, a power flow in the electrical transmission network, bids for regulation, an actual generation schedule, and set points of PFDs.

    摘要: A distribution controller is disclosed for controlling a distribution of electrical power in an assigned power distribution region. The controller is adapted to be communicatively connected to process or secondary devices (IEDs, RTUs) which in turn interact with primary devices of the assigned region. The controller includes a processing module executing algorithmic, logical or functional modules or client applications. The latter implement application function algorithms that calculate, based on process data from process devices connected to the controller, values of a power distribution quantity such as voltage, current, power flow, load, or a phasor quantity of the assigned region. The controller further includes, for the purpose of data exchange with the process devices communicatively connected to the controller, data servers. The controller is adapted for writing the output or results of the functional module, i.e. a value of the aforementioned power distribution quantity, to one of said data servers, and thus takes advantage of the existing controller structure.

A first phase difference between the first signal and the second signal is measured at the second location, and the length quantity is calculated from the measured phase difference. In the system, a second receiver at the second location is configured to receive the first signal having the first carrier frequency from the first location. A frequency generator creates the second signal having the second frequency at the second location. The receiver includes a phase detection device configured to detect a first phase difference between the second frequency and the first carrier frequency at the second location.

    摘要: Methods for detecting network model data errors are disclosed. In some examples, methods for detecting network model data errors may include splitting a network model into a first plurality of portions, executing an algorithm on each of the portions, identifying a portion for which the algorithm is determined to be non-converged, splitting the identified portion into a second plurality of portions, repeating the executing, identifying and splitting the identified portion until a resulting identified portion is smaller than a predefined threshold, and examining the resulting identified portion to identify plausible data errors therein. In some examples, examining the resulting identified portion to identify plausible data errors therein may include executing a modified algorithm, which may include an augmented measurement set, on the identified portion.

    摘要: The present disclosure is concerned with the combined voltage or power flow control and damping of electromechanical oscillations in an electric power system by Flexible AC Transmission System (FACTS) devices or High Voltage DC (HVDC) transmission devices. To this end, information about a state or operating point of the power system is generated from suitable second system signals (y2) and a control parameter (cp) of a FACTS controller is derived therefrom. The control parameter and a first system signal (y1) are used in the calculation of a control command (u) defining the settings of the FACTS device. Following a change in the state of the power system such as a change in the topology of a transmission network, poorly damped or even unstable oscillations are avoided by appropriate re-tuning of the control parameter of the damping or stabilizing equipment.
