Detailed long-term hydro-thermal scheduling for expansion planning in the Nordic power system
Assessing hydropower operational profitability considering energy and reserve markets
Water values in future power markets
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...
Economic impact of forecasting errors in residual reserve curves in the day-ahead scheduling of pumped storage plants
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 ...
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,...
(TR A7558) Balancing Markets and their Impact on Hydropower Scheduling
Hydropower Scheduling Considering Energy and Reserve Capacity Markets : Using a combined SDP/SDDP algorithm
Provision of rotating reserves from wind power in a hydro-dominated power system
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 ...
Valuation of stored energy in dynamic optimal power flow of distribution systems with energy storage
Dynamic optimal power flow (DOPF) models are needed to optimize the operation of a power system with energy storage systems (ESSs) over an extended planning horizon. The optimal storage level at the end of each planning horizon depends on the possible realization of uncertainties in future planning ...
