  2. Microgeneration - Wikipedia

    en.wikipedia.org/wiki/Microgeneration

    Microgeneration technologies include small-scale wind turbines, micro hydro, solar PV systems, microbial fuel cells, ground source heat pumps, and micro combined heat and power installations. [1] These technologies are often combined to form a hybrid power solution that can offer superior performance and lower cost than a system based on one ...

  3. Micro hydro - Wikipedia

    en.wikipedia.org/wiki/Micro_hydro

    Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro . [ 1 ] These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where ...

    en.wikipedia.org/wiki/Pump_As_Turbine

    In micro Pumped-storage hydroelectricity (PSH), the same pump/PAT could be used for pumping and generating phases [8] by changing rotational direction and speed. The best efficiency point in pumping usually differs from its reverse mode: [3] a variable-frequency drive coupled to the motor/generator would be needed in order to change from pumping to generating mode and to react efficiently to ...

    en.wikipedia.org/wiki/Pumped-storage...

    Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off ...

  7. Pico hydro - Wikipedia

    en.wikipedia.org/wiki/Pico_hydro

    A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes. [2]

    A schematic presentation of a gravitation water vortex power plant, showing the turbine in yellow. The gravitation water vortex power plant is a type of micro hydro vortex turbine system which converts energy in a moving fluid to rotational energy using a low hydraulic head of 0.7–3 metres (2 ft 4 in – 9 ft 10 in).
