  • A conceptual framework for real time estimation of WFP for small hydroelectric power plant

    It is believed that the power sector, particularly hydroelectric power, contributes to a very high consumption of fresh water in terms of evaporation from storage reservoirs. Robust methods of water footprint (WFP) assessment will eventually help in the pricing of water and energy. Conventionally, WFP for hydropower plants is estimated by dividing the gross/net evaporation losses by power ...

  • Applications of the anarchic society optimization (ASO) algorithm for optimizing operations of single and continuous multi-reservoir systems

    To address water resources-related management issues, different evolutionary and heuristic algorithms have been developed in recent years. In this paper, a new algorithm is introduced for optimizing the operation of reservoir systems. Specifically, the anarchic society optimization (ASO) algorithm is applied to solve water resources management problems for the first time. In these problems, ...

  • Extended multi-objective firefly algorithm for hydropower energy generation

    Classical methods have severe limitations (such as being trapped in local optima, and the curse of dimensionality) to solve optimization problems. Evolutionary or meta-heuristic algorithms are currently favored as the tools of choice for tackling such complex non-linear reservoir operations. This paper evaluates the performance of an extended multi-objective developed firefly algorithm ...

  • 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 ...

  • The Global Arc Towards Renewable Energy

    Introduction Given the United States’ recent election results, America’s future on climate and energy policy is uncertain, but global progress on mitigating climate change will continue with or without us. We have reason to be optimistic because countries around the world have demonstrated their commitments to taking action on global warming. Already, 114 countries have ...

  • 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 ...

  • An assessment of reservoir filling policies for the Grand Ethiopian Renaissance Dam

    Africa's largest hydropower facility is currently under construction on the main stem of the Blue Nile River in Ethiopia. The Grand Ethiopian Renaissance Dam (GERD) is poised to facilitate regional development with a 63 billion cubic meter reservoir and 6,000 MW of power generating capacity. To date, however, no reservoir filling rate policy has been established. This policy will have ...

  • Energy recovery in the water industry using micro-hydropower: an opportunity to improve sustainability

    The water industry as a whole consumes a considerable amount of energy in the treatment and distribution of water and wastewater. Like all sectors of society today, the industry is focusing efforts on reducing its CO2 emissions and improving the sustainability of its systems and practices. One way of achieving this is through the use of micro-hydropower (MHP) installations in water ...

  • SHP stations and integrated rural development: a multivariate statistical approach

    The multi-functional role of the rural space is gradually being enhanced in recent decades, as agriculture seems to be losing its leading position. The diversification of local economies through the exploitation of natural resources is being highlighted as a fundamental driving force for development. Renewable Energy Resources (RES) and, more specifically, the establishment of Small Hydropower ...

  • Large-scale hydropower system optimization using dynamic programming and object-oriented programming: the case of the Northeast China Power Grid

    This paper examines long-term optimal operation using dynamic programming for a large hydropower system of 10 reservoirs in Northeast China. Besides considering flow and hydraulic head, the optimization explicitly includes time-varying electricity market prices to maximize benefit. Two techniques are used to reduce the ‘curse of dimensionality’ of dynamic programming with many ...

  • Introduction to some kinds of renewable energy

    Clean energy is a kind of energy which does not produce pollutants in the use procedure. It includes nuclear energy and "renewable energy". Renewable energy refers to a kind of inexhaustible energy such as hydropower, wind power, solar energy, biomass energy (biogas), water energy, and tidal energy and so on. Renewable energy doesn’t have the possibility of energy depletion, and ...

  • Factsheet: Hydropower and ecology

    Accounting for 20% (around 3,400 TWh) of global electricity production – even though its contribution to gross final energy consumption is only about 2% – hydropower plays a vital role. This is largely due to the fact that it can be readily regulated to meet fluctuations in demand and substantial reserves can be stored in reservoirs. Hydropower supplies around 56% of Switzerland's ...

  • A Bayesian approach to probabilistic streamflow forecasts

    One-month-ahead streamflow forecasting is important for water utilities to manage water resources such as irrigation water usage and hydropower generation. While deterministic streamflow forecasts have been utilized extensively in research and practice, ensemble streamflow forecasts and probabilistic information are gaining more attention. This study aims to examine a multivariate linear ...

  • The blue water footprint of electricity from hydropower

    Hydropower accounts for about 16% of the world’s electricity supply. It has been debated whether hydroelectric generation is merely an in-stream water user or whether it also consumes water. In this paper we provide scientific support for the argument that hydroelectric generation is in most cases a significant water consumer. The study assesses the blue water footprint of hydroelectricity ...
