SOVN Model Implementation : method, functionality and details
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,...
Use of Parallel Processing in Applications for Hydro Power Scheduling – Current Status and Future Challenges
This paper gives an overview of models for hydro power scheduling and market simulation developed at SINTEF Energy Research. All of the models are in operative use by power producers, transmission system operators, consultants and regulators operating in the Nordic power market. Several of the model...
Stochastic Optimization Model for Detailed Long-term Hydro Thermal Scheduling Using Scenario-tree Simulation
The paper presents a case study comparing two models for hydro-thermal scheduling. Both models are tools that can be applied for forecasting and planning in electricity markets, taking into account inter-connected power markets and using detailed hydro modelling. The first model, which is used as th...
NORSTRAT – A carbon neutral power system in the Nordic region in 2050 – part 2
Hydrothermal scheduling in Norway using stochastic dual dynamic programming; a large-scale case study
We test the stochastic dual dynamic programming (SDDP) approach on a system an order of magnitude larger than previously published studies. The analysis shows that the SDDP-approach can be applied to very large system sizes to solve the hydropower scheduling problem through formal optimisation and o...
Space-time dependence between energy sources and climate related energy production
Analyzing and modeling CRE in a changing climate and energy system, - a case study from Mid-Norway
Integrating hydropower and intermittent climate-related renewable energies: a call for hydrology
Verification of a model for handling of pumped storage for large scale market balancing
With an increasing amount of intermittent renewable energy sources, such as wind and solar energy, there will also be an increasing demand for balancing power. Hydropower, and pumped storage in particular, can be an efficient way of providing the needed flexibility. Hydropower scheduling, particular...
