Abstract
Around the world, the energy sector is moving toward renewables and phasing out conventional power plants. This reduces the grid’s “inertia”—its natural resistance to sudden changes—and makes the system more vulnerable to power oscillations (small, repeating swings in the grid). In traditional plants, power system stabilizers were used to damp these oscillations. To keep the grid stable as renewables grow, wind farms need to deliver similar stabilizing functions. This thesis investigates and proposes practical control methods that can be implemented in wind turbines and/or wind power plants to mitigate power system oscillations. The focus is on solutions that manufacturers and plant owners can apply across different grid conditions worldwide, that provide effective damping for the power system, and that do not compromise safe turbine operation.
Verden over skifter energisektoren mod mere vedvarende energi og udfaser konventionelle kraftværker. Det mindsker elnettets "træghed"—dets naturlige modstand mod pludselige ændringer—og gør systemet mere sårbart over for netsvingninger (små, gentagne udsving i elnettet). I traditionelle kraftværker brugte man stabilisatorer i kontrolsystemet til at dæmpe disse svingninger. For at bevare stabilitet og forsyningssikkerhed må vindmøllepar kunne levere tilsvarende stabiliserende funktioner. Dette projekt undersøger og foreslår praktiske styringsmetoder, der kan implementeres i vindmøller og/eller vindkraftanlæg for at dæmpe svingninger i elnettet. Fokus er på løsninger, som producenter og anlægsejere kan anvende på tværs af forskellige netforhold verden over, som giver effektiv dæmpning af elnettets svingninger, og som ikke bringer vindmøllernes sikre drift i fare.
