Economic impact of forecasting errors in residual reserve curves in the day-ahead scheduling of pumped storage plants

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1489908

The economic impact of forecasting errors in the residual demand curves of the secondary regulation reserve market is analysed in the context of the operation of a closed-loop and daily-cycle pumped-storage hydropower plant. The plant participates in the day-ahead energy market as a price-taker and ...

Water values in future power markets

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1489911

In this paper we elaborate on how a hydropower producer's expected marginal value of water (water value) is affected when considering both sales of energy and reserve capacity in a liberalized market setting. We derive analytical expressions for the water value in this market context, and verify the...

SOVN Model Implementation : method, functionality and details

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1479047

The SOVN project ("Stokastisk optimaliseringsmodell for Norden med individuelle vannverdier og nettrestriksjoner") aimed at creating a new fundamental hydro-thermal market model with detailed representation of the hydropower system. The model is based on a combination of optimization and simulation,...

Combined SDDP and simulator model for hydropower scheduling with sales of capacity

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1379757

In following work, we investigate the importance of detailed hydropower scheduling modelling when including sales of capacity, which adds complexity that is not easily incorporated in a Linear Programming (LP) problem. In the proposed approach, we use the profit-to-go function obtained from a Stocha...

Hydro-thermal market model based on price decoupling and local supply/demand curves

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1379759

This paper describes a new approach for optimization and simulation of hydro-thermal systems. The approach mimics how the market is operated and utilizes the same tools as the market players. One of the major complexities in hydrothermal optimization models are caused by the number of hydro storages...

Modeling start/stop in short-term multi-market hydropower scheduling

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1379761

We present a hydropower scheduling model for coordinated trade in the day-ahead and balancing market with alternative ways to represent generator start/stop decisions. A case study on a branch of a Norwegian water course is conducted, with analysis going in two directions: how does the start/stop fe...

Modeling the Real-Time use of Reserves in the Joint Energy and Reserve Hourly Scheduling of a Pumped Storage Plant

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1331894

This paper studies the impact that different approaches of modeling the real-time use of the secondary regulation reserves have in the joint energy and reserve hourly scheduling of a price-taker pumped-storage hydropower plant. The unexpected imbalance costs due to the error between the forecasted r...

A Case Study on Medium-Term Hydropower Scheduling with Sales of Capacity

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1331936

This paper conducts a case study on hydropower scheduling considering sales of capacity reserves and impacts of detailed mod-elling. In latter years a growing demand for reserve capacity has been needed to ensure stable operation in the power grid which has given the power producers incentives to co...
