Abstract
Efterhånden som mere strøm kommer fra vind, stiller de virksomheder, der driver højspændingsnettet (transmissionssystemoperatører, TSO’er), nye krav for at bevare stabiliteten i elsystemet. Vindparker forventes nu at støtte elnettet på linje med konventionelle kraftværker. Dette projekt implementerer et kontrolsystem for vindkraft, der opfylder de danske netregler. Vi modellerer vindkraftsystemet, tilslutning til nettet og vindparkens overordnede kontrolarkitektur og vurderer deres ydeevne. I modellen implementerer vi styring af aktiv effekt (den reelle leverede effekt) og reaktiv effekt (spændingsstøtte). Resultaterne viser, at disse funktioner gør det muligt for vindparker at bidrage markant til systemets stabilitet. Vi opbygger også en dynamisk RMS-simulationsplatform med en reduceret model af en vindpark, en VSC-HVDC transmissionsforbindelse (en styrbar højspændings-jævnstrømsløsning) og en vindparkcontroller, implementeret i Power Factory DIgSILENT. Platformen kan bruges i fremtidige studier.
As more electricity comes from wind, the organizations that operate the high-voltage grid (Transmission System Operators, TSOs) set new requirements to keep the power system stable. Wind farms are now expected to support the grid much like conventional power plants. This project implements a wind power control system that meets Danish grid regulations. We model the wind power system, grid connection methods, and the overall wind farm control architecture, and assess their performance. In the model, we implement active power control (managing the real power delivered) and reactive power control (supporting voltage). The results show that these functions enable wind farms to provide strong support to system stability. We also build a dynamic RMS simulation setup with a reduced wind farm model, a VSC-HVDC transmission link (a controllable high-voltage direct current system), and a wind farm controller, implemented in Power Factory DIgSILENT. This platform is available for future studies.
