In this paper, we introduce an operational implementation of a hydropower simulator for cascaded river systems. It is presently used for decision support in the intraday re-planning by the largest hydropower producer in Norway. It simulates the hydro production at a highly detailed level with very f...

When participating in the real-time balancing markets, hydropower producers keep making decisions about how much power they are willing to sell or purchase at what prices from the markets. Due to the specific market characteristics, the decisions should be made quickly, placing high demand on the co...

In this paper a new approach to generate strategies for hydro reservoir scheduling is presented. The idea is that the marginal value of water in one reservoir can be calculated by dynamic programming under some simple assumptions on the content in other reservoirs. A benefit of this approach is that...

In this paper a new method to find optimal strategies for scheduling of pumped hydro storage reservoirs is presented. Allowing start-up costs and non-linear head variations to be handled within a formal optimization algorithm shows increased value for hydro storage operators. Two cases are presented...

Traditional modeling of hydropower systems consist of a two-step process. The first part is a strategic analysis of seasonal inflow producing water values as guidelines for reservoir utilization. In the second part these guidelines are used as input for a short-term model with a finer resolution res...
