As the penetration of variable renewable power generation increases in power systems around the world, system security is challenged. It is crucial to coordinate the available flexible generating resources, such as hydropower, to meet the need for system balancing. However, reserved capacity on hydr...

This paper presents a framework for long-term price forecasting in hydro-thermal power systems comprising two modeling layers. A long-term hydro-thermal model expresses the expected future cost as a function of hydro reservoir levels to a short-term operational model. The short-term model re-optimiz...

This paper studies the stochastic short term hydrothermal scheduling of systems that have a significant contribution from controllable reservoirs, focusing on the reservoirs’ operation policy when non-linearity and deployment of supplementary reserves at the real operation stage are modeled. Wind po...

Decreasing costs of battery storage technologies make them a viable option for providing flexibility in power systems. In this paper, we study the operations of a battery in combination with cascaded hydropower in a system with uncertain net load due to wind power production. By simulating the opera...

The economic effects of forecasting inaccuracies in the automatic frequency restoration service is analyzed in the context of the operation of a closed-loop and daily-cycle pumped-storage hydropower plant. The uncertainties when scheduling the automatic frequency restoration service are composed by ...

We propose a model for medium-term hydropower scheduling (MTHS) with variable head and uncertainty in inflow, reserve capacity, and energy price. With an increase of intermittent energy sources in the generation mix, it is expected that a flexible hydropower producer can obtain added profits by part...
