Stabilization of large power systems using VSC-HVDC and model predictive control

摘要

Summary form only given. This paper demonstrates the stabilization of large power systems using voltage source converter based high voltage direct current (VSC-HVDC) links. Based on global power system measurements, a model predictive controller (MPC) manipulates the power injections of the HVDC links to keep the AC system in synchronism. The grid controller explicitly accounts for constraints and the future behavior of the system. Different scenarios like the loss of production, the loss of consumption and changes to the grid topology are studied in the continental European Network of Transmission System Operators for Electricity (ENTSO-E) system. The simulations illustrate the performance enhancement obtained with a global MPC-based grid controller, compared to a local damping controller and HVDC links with constant reference values.
