Joint Optimal Operation of Wind Power Plant and Cascade Hydropower Station
IOP Conference Series: Earth and Environmental Science, 2021 Abstract With the depletion of fossil energy, the whole people advocate energy conservation and emission reduction, making the scale of wind power integration increase. While wind power has fluctuating and intermittent characteristics, this paper develops a short-term combined operation strategy of wind and water using the flexible ...

Practical Day‐Ahead Gas Generator Dispatch Optimisation for Enhancing the Reserved Capacity
IET Smart Energy Systems, EarlyView.Practical day‐ahead gas generator dispatch optimisation model is proposed to enhance the system reserved capacity. ABSTRACT In order to reduce carbon dioxide emissions, traditional coal‐fired power generation has been strictly limited in China recently, which has led to the problem of reserved capacity shortage. As one of the critical east provinces of

Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal
Fisheries Management and Ecology, EarlyView.ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).

Multi-Station Equivalents for Short-Term Hydropower Scheduling
, 2016 Hydropower scheduling in day-ahead electricity markets is complex due to uncertainty in the electricity price. Internal cascade dependency of hydro power plants can also increase this complexity.

The influence of rivers on seabird foraging ecology
Biological Reviews, Volume 101, Issue 4, Page 1704-1734, August 2026.ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Production Planning of Cascaded Hydropower Stations using Approximate Dynamic Programming
IFAC-PapersOnLine, 2023 We formulate the day-ahead bidding problem for a hydropower producer having several hydropower plants residing in a river basin. We present a novel approach inspired by Dynamic programming with approximations in value and policy space by neural networks.

Modelling bedload transport at the network scale in a glacier‐fed Alpine river system
Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.We adapted the network‐scale sediment transport and connectivity model D‐CASCADE for Alpine environments and applied it to the Sulden/Solda catchment (Italy). For the first time, we validate the model with continuous bedload measurements at the catchment outlet and evaluate the plausibility of bedload dynamics along the river network with field ...
