Evaluation on operation management of cascade hydropower stations
2011 IEEE International Conference on Industrial Engineering and Engineering Management, 2011An evaluation framework for joint operation of cascade hydropower stations was developed in this study. This framework is helpful to evaluate the operation performance of the cascade hydropower stations in order to improve the operation level. The power benefit of the cascade hydropower stations is chosen to be the evaluation object for multipurpose ...

Research of Compensating Weights of Cascade Hydropower Stations
Applied Mechanics and Materials, 2012The compensation benefits distribution weights model of cascade hydropower stations has been proposed. The method of compensation weights calculation has been discussed. The subjective weights in the station indexes are calculated by analytic hierarchy process and the objective weights by variance coefficient and the combination weights by Topsis.

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.

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.

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
