  • Control systems for small hydropower plants: a review

    Hydropower is emerging as a major contributor to world energy requirement. It is inexhaustible, clean and has many other benefits like flood mitigation, water supply, irrigation, etc. However, large-scale hydropower generation suffers from inherent disadvantages, such as massive financial outlays, long gestation periods, geological surprises, environmental factors and rehabilitation of the ...

  • How to make hydropower more environmentally friendly

    Hydropower provides 85 percent of the world’s renewable electricity, but comes with a hefty environmental price tag. Here’s what some are doing to fix that. Humanity got its first large-scale electricity thanks to hydropower. On Aug. 26, 1895, water flowing over Niagara Falls was diverted to spin two generators, producing electricity to manufacture aluminum and carborundum. Since ...

  • Optimal control of reservoir release temperature through selective withdrawal intake at hydropower dam

    This study is motivated by the need to understand the temperature dynamics and warm-water temperature withdrawal. This study also recognizes the need for an environmental assessment of the proposed temperature control schemes at New Fengman Dam. An unsteady three-dimensional (3D) non-hydrostatic model is used in the present study to predict the hydrodynamics and thermal dynamics in the forebay ...

  • Capacity optimization of hydropower storage projects using particle swarm optimization algorithm

    A mixed integer optimization model is formulated for capacity optimization of a hydropower storage project with control on reliability of meeting the project's firm energy yield. Particle swarm optimization (PSO) is used as the optimization algorithm, in which the method of sequential streamflow routing is called for objective function evaluations. Two types of problems are studied. The first one ...

  • Limited adaptive genetic algorithm for inner-plant economical operation of hydropower station

    A limited adaptive genetic algorithm (LAGA) is proposed in the paper for inner-plant economical operation of a hydropower station. In the LAGA, limited solution strategy, with the feasible solution generation method for generating an initial population and the limited perturbation mutation operator, is presented to avoid hydro units operating in cavitation–vibration regions. The adaptive ...

  • Prediction of ungauged river basin for hydropower potential and flood risk mitigation: a case study at Gin River, Sri Lanka

    A hydrologic study was performed for ungauged river basin of Sri Lanka to examine synthetic discharge relations. Rainfall-runoff relationships were used for identifying hydrological conditions of the Gin River basin. The peak discharge achieves within 4.74 hours from the onset of the rainstorm and 11.95 hours take to reach its normal discharge conditions. Stream frequency of the Gin River is ...

  • Control of dynamic effects in small hydro with long hydraulic circuits

    Lab tests in a long hydraulic circuit were developed to analyse hydrotransients induced by waterhammer effects under runaway conditions. The definition of suitable design criteria in hydraulic systems is of utmost importance and has become a priority for good design implementation. The dynamic behaviour of turbo-generators of small reaction turbines and the interaction with long hydraulic ...

  • As Global Demand for Electricity Grows, Geothermal Energy Heats Up

    January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of ...
