Optimal Sequencing of Development for Hydropower Stations in Cascade
Journal of Water Resources Planning and Management, 1989The sequencing problem for hydropower station development is a multi-dimensional problem involving space-time decisions. In this paper, a mathematical model that uses a combination of dynamic programming and mixed-integer programming is developed, and an efficient algorithm for its use in optimal sequencing problems is presented.

Cumulative effects of cascade hydropower stations on total dissolved gas supersaturation
Environmental Science and Pollution Research, 2018Elevated levels of total dissolved gas (TDG) may occur downstream of dams during the spill process. These high levels would increase the incidence of gas bubble disease in fish and cause severe environmental impacts. With increasing numbers of cascade hydropower stations being built or planned, the cumulative effects of TDG supersaturation are becoming

Regulation capability of small cascade hydropower stations for photovoltaic generation
Journal of Renewable and Sustainable Energy, 2020The stochasticity of photovoltaic (PV) generation output makes it necessary to smooth the output using other flexible power sources to realize the scale development of PV power. Small cascade hydropower stations (SCHSs) are also widely distributed in space, like PV generation.

Complementary operation of a small cascade hydropower station group and photovoltaic power stations
Clean Technologies and Environmental Policy, 2020Complementation with hydropower is an important solution to solve the problems of grid connection and consumption of photovoltaic generation. Considering the randomicity of photovoltaic output and runoff, hydropower station with good regulation capability is often used as a complementary power source of photovoltaic generation.

Cascade hydropower station risk operation under the condition of inflow uncertainty
Energy, 2022Abstract Runoff is an important basis for the operation of hydropower. However, due to inflow uncertainty, the ideal practical operation process usually doesn't match with the plan, which exacerbates the power generation and ecological risks. Therefore, the purpose of this paper is to investigate the relationship between hydropower generation ...

Optimize Dispatchers of Cascade Hydropower Station Based on IS-NGA
2013 Third International Conference on Intelligent System Design and Engineering Applications, 2013Because the short-time optimized dispatcher question has some characteristics such as high dimension, non-protruding, dispersed, non-linear etc., so need one algorithm with high calculation precise and convergence speed to solve this question. This paper put forward one improve self-adaptation niche genetic algorithm, its characteristic mainly is ...
