Förändringar av marknadsdesign och deras påverkan på balanshållningen i det svenska kraftsystemet: En kartläggning och analys av de balansansvarigas arbetsgång
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
A future expansion of wind power in the Nordic power system makes the balancing for the transmission system operator Svenska Kraftnät (SvK) more complicated. Up to the hour of delivery the balance responsible parties’ (BRP) makes prognoses and plans, for consumption and production, to help maintain the balance in the electrical grid. How well this is accomplished is affected by the setup of the market design. Therefore SvK has proposed the following possible changes in market design:
- Increase the imbalance costs
- Intensify the regulation of imbalances
- Increase the temporal resolution on the different markets
- Present the prices for balancing power in real-time
- Modify the balancing market to simplify auction of consumption bids
A mapping over the BRPs’ processes within planning and trading on the day-ahead, intra-day, and the balancing market has been performed in this thesis. This mapping shows that the actual processes differ from the theoretical. How they differ depends on the size of the BRP, hence a categorization has been carried out with regards to their share of production in the electrical grid. The results show that the different market changes affect the categories in different ways as well.
The analysis shows that increased imbalance costs, intensified regulation of imbalances and modification of the balancing market to simplify auction of consumption bids are the most beneficial changes from the systems perspective. Finally a discussion covers how these changes could be conducted, along with the possible implications that might occur. Implications could be increased electricity prices and economies of scale for larger BRP’s.
