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 and rotating reserve (RR) cost. Due to the flexibility provided by hydropower, the system is well suited...
In this article we study the effects of participation in a hypothetical rotational energy market alongside the day-ahead and primary frequency reserve markets on medium-term hydropower scheduling. Participants in the rotational energy market, where the hydropower unit operates in synchronous condenser mode, are remunerated for provision of rotational energy that does not alter production. Stochastic...
In this work we use a production scheduling model based on Stochastic Dual Dynamic Programming (SDDP) to investigate the effects of coordinating hydro and wind power production in a transmission-constrained area. A case study is performed on an aggregated representation of a region in western Norway for a future situation with a significant integration of wind power. Two strategies for hydro reservoir...
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 Stochastic Dual Dynamic Programming (SDDP) scheduling-model in a Simulator Model, based on Mixed Integer Programming...
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 commence methods for co-optimization of energy and capacity. In this paper we will assess the value of...
This paper describes a model for optimal scheduling of hydroelectric systems for a price-taking producer selling energy and capacity to separate markets. The model is based on a combination of stochastic dynamic programming (SDP) and stochastic dual dynamic programming (SDDP), and treats inflow to reservoirs and energy prices as stochastic variables. It allows sales of capacity at a deterministic...
