Definitions

  • the invention relates to the field of control of power systems comprising a High- Voltage Direct-Current (HVDC) link with a Voltage-Source Converter (VSC).
  • HVDC High- Voltage Direct-Current
  • VSC Voltage-Source Converter
  • VSC Voltage-Source Converters
  • HVDC High- Voltage Direct-Current
  • VSC HVDC The main control challenge for the operation of VSC HVDC systems is achieving a stable and reliable operation over a wide range of operating conditions and system parameters. Moreover, suppression of transient overvoltages and overcurrents is crucial for the operation of the system.
  • State-of-the-art control solutions for VSC in HVDC applications are based on the design of controllers using locally linearized and/or averaged models which are hardly capable of predicting or analyzing the emergence of local instabilities, since the dynamics that are causing them are not properly reflected in the controller design.
  • Model-based prediction of a power system's future behaviour reveals insights into a future evolution of emerging local instabilities in the power system, and allows comparing the effect of different control inputs on said evolution.
  • MPC takes into account, in a standard straightforward way, any physical, safety and operating constraints on the power system.
  • the control system for VSCs in HVDC applications has to be designed for the complete operating range of the power system, avoiding performance degradation when moving away from a specific operating point.
  • a present state of the power system comprising the VSC and the HVDC link is measured at the beginning of every switching period, the latter being the inverse of the switching frequency of the power semiconductor converter switches of the VSC and ranging from 1 to 5 kHz.
  • a control input or action such as a set of numerical values of duty cycles for the individual converter switches, is calculated and applied to the VSC in order to achieve a certain control objective or goal.
  • the sequence of optimal future control inputs is obtained by evaluating, and in particular minimizing, an objective, target or cost function.
  • the objective function in turn depends on future states or an anticipated behaviour of the power system, as predicted by a suitable model of the power system in conjunction with future control inputs, and at the same time satisfies predetermined constraints on the power system.
  • the model of the power system includes at least the VSC and HVDC link, as well as adjacent sections of the power network.
  • the objective function expresses a system control objective such as the avoidance of local instabilities, and also penalizes the deviation of the controlled variables from their references as well as the difference between consecutive duty cycles over the prediction horizon, using the 1-, 2- (or quadratic) or infinity norm.
  • the predetermined constraints are expressing physical (duty cycles are bounded between 0 and 1) safety (current limitation in case of a fault) and operational constraints of the power system.
  • the prediction model of the power system is discrete- time and Piecewise Aff ⁇ ne (PWA). Consequently,
  • control method is model-based and predictive. It comprises a discrete-time prediction model, used to predict the future behaviour of the system, the expression of the system's control objectives in an objective, target, performance or cost function, and the solution of an optimization problem consisting of the minimization of the objective function over a future prediction horizon, subject to the predicted system evolution and the system's constraints.
  • the model of the power system instead of focusing on a specific operating point, captures the dynamics of the system and is valid for the complete operating range. This results in a control system that can deal more effectively with disturbances pushing the system away from its original operating point.
  • the present invention also relates to a computer program product including computer program code means for controlling one or more processors of a control system for a power system comprising an HVDC link with a VSC, particularly, a computer program product including a computer readable medium containing therein the computer program code means.
  • Fig.l schematically shows a power system comprising an HVDC link with a VSC
  • Fig.2 depicts the basic principles of MPC.
  • the reference symbols used in the drawings, and their meanings, are listed in summary form in the list of reference symbols.
  • Fig.l shows a power system 1 comprising generators 2 and a power transmission network with a High-Voltage Direct-Current HVDC link 3 and two Voltage-Source Converters VSC 4 connecting the HVDC link to the rest of the power transmission network.
  • Fig.2 depicts the main principles of Model Predictive Control as applied to a power system.
  • the evolution in time of an overall state of the power system or a particular physical system quantity, such as the voltage at a certain node of a transmission network, is represented by a one- or multidimensional trajectory.
  • a power system model taking into account its dynamics is used to predict output trajectories (x 1 ) based on the current state at time to and for several different potential candidate input sequences ( ⁇ x 1 ).
  • An objective or cost function is then defined based on the deviation of each predicted trajectory from a desired reference trajectory (xref) over a window in time called the prediction interval (t p ).

Abstract

La présente invention concerne des réseaux électriques comprenant une liaison de courant continu à haute tension (CCHT) associée à un convertisseur de source de tension (CST). Le procédé de commande selon l'invention est basé sur un modèle et de type prédictif. Il comprend un modèle de prédiction en temps discret, utilisé pour prédire le comportement futur du système, l'expression des objectifs de commande du système en fonction des objectifs ou du coût et la solution d'un problème d'optimisation résidant dans la minimisation de la fonction objectif sur un horizon de prédiction à venir, soumis à l'évolution du système prédite et des contraintes du système. Le modèle du réseau électrique, plutôt que de se focaliser sur un point de fonctionnement spécifique, s'empare de la dynamique du système et se trouve valide sur toute la plage de fonctionnement. Ceci produit par conséquent un système de commande qui peut gérer plus efficacement les perturbations qui font dévier le système de son point de fonctionnement de départ.
