SOVN Model Implementation : method, functionality and details

http://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,...

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

http://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

http://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...

Stochastic network constrained hydro-thermal scheduling using a linearized progressive hedging algorithm

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1305680

A method for solving the stochastic network constrained hydro-thermal scheduling problem based on the progressive hedging algorithm (PHA) is presented. The quadratic penalty terms in the PHA are dynamically linearized to retain a linear problem structure. Furthermore, a technique for efficient treat...

Optimal medium-term hydropower scheduling considering energy and reserve capacity markets

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1309706

Print Request Permissions This paper describes a method for optimal scheduling of hydropower systems for a profit maximizing, price-taking, and risk neutral producer selling energy, and capacity to separate and sequentially cleared markets. The method is based on a combination of stochastic dynamic ...

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

http://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

http://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...

Economic Analysis of Large-Scale Pumped Storage Plants in Norway

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1331938

The European power system needs to develop mechanisms to compensate for the reduced predictability and high variability that occur when integrating renewable energy. Construction of pumped storage plant (PSP) is a solution. In this article an economic analysis of large-scale PSP in Norway is made co...
