Norway as a Battery for the Future European Power System – Comparison of Two Different Methodological Approaches
This paper compares the simulation results for two stochastic optimization power market models. EMPS uses aggregation and heuristics to calculate the optimal dispatch. SOVN simulates the operation of the power system in one large linear programming problem taking each single plant and reservoir into...
Benchmarking Hydro Operation by Use of a Simulator
The paper describes how a simulator is used to benchmark TrønderEnergis’ historical operation of one of their hydro systems. The simulator is a data program that simulates daily hydro optimization and scheduling tasks for the historical period 2005 to 2015. The purpose of the benchmark is to ev...
Modeling and Quantifying the Importance of Snow Storage Information for the Nordic Power System
This paper describes how snow storage information can be used to improve the hydro operation strategy in a newly developed hydrothermal market simulation model. The model was applied to a detailed description of the Nordic system, and simulation results show that the value of knowledge about the sno...
Multi-Market Price Forecasting in Hydro-Thermal Power Systems
This paper presents a framework for price forecasting in hydro-thermal power systems. The framework consists of a long-term strategic and a short-term operational model. The strategic model provides the end-of-horizon valuation of water in hydro storages as input to the operational model. We emphasi...
Optimal Hydropower Maintenance Scheduling in Liberalized Markets
Maintenance scheduling is an important and complex task in hydropower systems. In a liberalized market, the generation company will schedule maintenance periods to maximize the expected profit. This paper describes a method for hydropower maintenance scheduling suitable for a profit maximizing, pric...
Detailed long-term hydro-thermal scheduling for expansion planning in the Nordic power system
Norway as a Battery for the Future European Power System—Impacts on the Hydropower System
Future power production in Europe is expected to include large shares of variable wind and solar power production. Norway, with approximately half of the hydropower reservoir capacity in Europe, can contribute to balance the variability. The aim of this paper is to assess how such a role may impact ...
