2. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: solar panel , wind turbine , hydro-electric , and the grid.

3. Grid-tied electrical system - Wikipedia

   en.wikipedia.org/wiki/Grid-tied_electrical_system

   A grid-tied electrical system, also called tied to grid or grid tie system, is a semi-autonomous electrical generation or grid energy storage system which links to the mains to feed excess capacity back to the local mains electrical grid. When insufficient electricity is available, electricity drawn from the mains grid can make up the shortfall ...

4. Raum Energy Inc. - Wikipedia

   en.wikipedia.org/wiki/Raum_Energy_Inc.

   Raum Energy Inc. was a company based in Saskatoon, Saskatchewan, Canada which designed and manufactured small-scale wind turbines, grid-tie inverter and battery charge controller systems. These systems, which could run off of either wind or photovoltaic generated power, were specifically designed for use with residential-scale applications.

5. Cost of electricity by source - Wikipedia

   en.wikipedia.org/wiki/Cost_of_electricity_by_source

   Son estimated that if these costs were included, the cost of nuclear power was about the same as wind power. [130] [131] [132] More recently, the cost of solar in Japan has decreased to between ¥13.1/kWh to ¥21.3/kWh (on average, ¥15.3/kWh, or $0.142/kWh). [133] The cost of a solar PV module make up the largest part of the total investment ...

6. Inverter-based resource - Wikipedia

   en.wikipedia.org/wiki/Inverter-based_resource

   An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation (CIG), include the variable renewable energy generators (wind, solar) and battery storage power stations. [1]

7. Wind power in the United States - Wikipedia

   en.wikipedia.org/wiki/Wind_power_in_the_United...

   For power contracts made in the year 2014, the average price of wind power fell to 2.5¢/kWh. [42] The capacity factor is the ratio of power actually produced divided by the nameplate capacity of the turbines. The overall average capacity factor for wind generation in the US increased from 31.7% in 2008, to 32.3% in 2013. [43]

8. Wind turbine design - Wikipedia

   en.wikipedia.org/wiki/Wind_turbine_design

   An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub

9. Short circuit ratio (electrical grid) - Wikipedia

   en.wikipedia.org/wiki/Short_circuit_ratio...

   The term grid strength (also system strength) is used to describe the resiliency of the grid to the small changes in the vicinity of the grid location (“grid stiffness”). [5] From the side of an electrical generator, the system strength is related to the changes of voltage the generator encounters on its terminals as the generator's current ...
