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. 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]

5. Interconnector - Wikipedia

   en.wikipedia.org/wiki/Interconnector

   An interconnector (also known as a DC tie in the USA [1]) is a structure which enables high voltage DC electricity to flow between electrical grids. An electrical interconnector allows electricity to flow between separate AC networks, or to link synchronous grids .

6. Islanding - Wikipedia

   en.wikipedia.org/wiki/Islanding

   In a power outage, the microgrid controller disconnects the local circuit from the grid on a dedicated switch and forces any online distributed generators to power the local load. [ 3 ] [ 4 ] Unintentional islanding is a dangerous condition that may induce severe stress on the generator, as the generator must match any changes in electrical ...

7. Stand-alone power system - Wikipedia

   en.wikipedia.org/wiki/Stand-alone_power_system

   Reactive power: The circulating current can differ from the current consumed when capacitive or inductive loads are used. Harmonic distortion: Non-linear loads may create distortion of the inverter waveform. Mismatch between load and inverter size: When a higher rated inverter is used for a lower capacity load, overall efficiency is reduced. [9]

8. HVDC converter station - Wikipedia

   en.wikipedia.org/wiki/HVDC_converter_station

   When line commutated converters are used, the converter station will require between 40% and 60% of its power rating as reactive power. This can be provided by banks of switched capacitors or by synchronous condensers, or if a suitable power generating station is located close to the static inverter plant, the generators in the power station ...

9. Wikipedia:Cleanup Taskforce/String inverter - Wikipedia

   en.wikipedia.org/.../String_inverter

   The term "string inverter" is somewhat nonsensical in this context because the small-scale wind generators are not typically done in arrays like solar panels and there is typically only a single generator per installation (for small systems). Now high-DC-voltage "grid-tie string inverters" are all the rage for use in wind systems, too.
