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,...

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...

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

http://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...

Provision of rotating reserves from wind power in a hydro-dominated power system

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1422561

This paper investigates how wind power can contribute to the provision of rotating reserves in a hydro-dominated power system with limited transmission capacity to an exogenous power market. We emphasize on the impacts different schemes for providing rotating reserves has on the generation dispatch ...

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...

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

http://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...

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

http://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...

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...

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...
