  2. Droop speed control - Wikipedia

    en.wikipedia.org/wiki/Droop_speed_control

    Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid .

  3. Voltage droop - Wikipedia

    en.wikipedia.org/wiki/Voltage_droop

    Voltage droop is the intentional loss in output voltage from a device as it drives a load. Adding droop in a voltage regulation circuit increases the headroom for load transients . All electrical systems have some amount of resistance between the regulator output and the load.

  4. Electrical grid - Wikipedia

    Conversely, when the grid is heavily loaded, the frequency naturally slows, and governors adjust their generators so that more power is output (droop speed control). When generators have identical droop speed control settings it ensures that multiple parallel generators with the same settings share load in proportion to their rating.

  5. Automatic generation control - Wikipedia

    en.wikipedia.org/wiki/Automatic_generation_control

    An electrical grid may have many types of generators and loads; generators must be controlled to maintain stable operation of the system. In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load.

  6. Synchronization (alternating current) - Wikipedia

    en.wikipedia.org/wiki/Synchronization...

    The voltage, frequency and phase angle must be controlled each time a generator is to be connected to a grid. [1] Generating units for connection to a power grid have an inherent droop speed control that allows them to share load proportional to their rating. Some generator units, especially in isolated systems, operate with isochronous ...

  7. Flexible AC transmission system - Wikipedia

    en.wikipedia.org/wiki/Flexible_AC_transmission...

    Power flow must be calculated and controlled at each node (substation bus) to ensure the grid design and topology itself does not prevent generated electricity from reaching loads, [10] as when Transmission Lines reach dozens to hundreds of miles in length, they add significant impedance and voltage drop to the system.

  8. Regional transmission organization (North America) - Wikipedia

    en.wikipedia.org/wiki/Regional_transmission...

    The former Grid West participants who had argued for an eventual RTO, mainly investor-owned utilities and state representatives from Oregon, Idaho, Montana, Wyoming and Utah, formed the Northern Tier Transmission Group (NTTG), a nascent effort open to evolution but initially focused on inexpensive and relatively easy improvements to grid ...

  9. Short circuit ratio (electrical grid) - Wikipedia

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

    [citation needed] In a traditional grid dominated by synchronous generators, a strong grid with SCR greater than 3.0 will have the desired voltage stability and active power reserves. [4] A weak grid (with SCR values between 2.0 and 3.0 [6]) can exhibit voltage instability and control problems. [5] A grid with SCR below 2.0 is very weak. [6]
