De masterproef kadert binnen de huidige maatschappelijke uitdaging richting duurzame energieproductie, met een focus op windenergieproductie. Het onderzoekt potentiële verbeteringen in de penetratie van windenergie in de groothandelselektriciteitsmarkt, meer bepaald de day-ahead
elektriciteitsmarkt. Hierbij onderzoekt de masterproef de invloed van een regelgevend kader waarin individuele windenergievoorspellingen van diverse windenergieproducenten onderling uitgewisseld en gedeeld kunnen worden.
Specifiek wordt een model geconstrueerd dat het strategische energiemanagement van elke energieproducent in de groothandelselektriciteitsmarkt simuleert. Hierbij brengt elke producent een strategisch offer uit op de day-ahead markt aan een bepaalde strategische minimumprijs. Het principe van vraag en aanbod zorgt tot slot voor een correcte marktwerking. De masterproef gaat echter nog een stap verder en breidt het model verder uit, waarbij de hoeveelheid informatie die een energieproducent bezit over het strategisch gedrag van zijn concurrerende energieproducenten een rol speelt.
Dit model wordt toegepast op een fictief elektriciteitssysteem, geïnspireerd door de Belgische Belpex markt. Naast waardevolle inzichten in het strategisch biedgedrag van energieproducenten op de markt, worden de principes van marktmacht en imperfecte competitie zichtbaar. Wanneer elke energieproducent het strategisch gedrag van zijn concurrerende energieproducenten kan simuleren omdat elke energieproducent zijn individuele productievoorspelling deelt, dan zal de penetratie van windenergie in de day-ahead elektriciteitsmarkt lager zijn. Dit omwille van lagere offers van de producenten op de markt, zodat een hogere elektriciteitsprijs veroorzaakt kan worden. Additioneel wordt de geldigheid van bovenstaande conclusie getest bij veranderende parameters (risicoaversie, onzekerheid in windenergievoorspellingen,...).
Onderzoek naar de invloed van informatie-delende energieproducenten is relatief recent. De masterproef stelt mede daarom een uniek model voorop in de academische literatuur. Het model kan dienen voor energieproducenten die hun strategisch energiemanagement wensen te optimaliseren (via een verhoogde gerealiseerde winst) door rekening te houden met eventuele informatie over concurrerende producenten via historische data of geografische correlaties.
