Operational use of marginal cost curves for hydropower plants as decision support in real-time balancing markets

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1482566

When participating in the real-time balancing markets, hydropower producers keep making decisions about how much power they are willing to sell or purchase at what prices from the markets. Due to the specific market characteristics, the decisions should be made quickly, placing high demand on the co...

Operational hydropower scheduling with post-spot distribution of reserve obligations

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1482562

As a reliable and flexible electric power source, hydropower can quickly adjust its generation level and provide reserve power to balance the power fluctuations in the system. In this paper, we assume that the day-ahead spot market is cleared and the obligation for each reserve type is already contr...

Optimizing day-ahead bid curves in hydropower production

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1454798

In deregulated electricity markets, hydropower producers must bid their production into the day-ahead market. For price-taking producers, it is optimal to offer energy according to marginal costs, which for hydropower are determined by the opportunity cost of using water that could have been stored ...

Increased Information Flow between Hydropower Scheduling Models through Extended Cut Sharing

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1331932

We present initial results and description of a method for coupling long term hydro scheduling models to short term hydro schedul- ing models. The method is based on an established approach but extends on the principle to increase the available information of the future estimates provided by the lon...

Modelling Minimum Pressure Height in Short-term Hydropower Production Planning

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1331922

When planning the production for certain hydropower plants, minimum pressure is one of the major critical points. Violation of the minimum pressure causes the power plant to automatically shut down, hence violating the obligations of the plant. Automatic pressure switches and pressure constraints ar...

Comparing Bidding Methods for Hydropower

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1331907

In this paper we compare several methods used by hydropower producers for the determination of bids to the day-ahead market. The methods currently used by the hydropower industry are based on heuristics and expert assessments, but we also include a new method for formal optimization of the bid decis...
