{{Short description|Specifications for electrical grids}}

A '''grid code''' is a technical specification which defines the parameters a facility connected to a public [[electric networkgrid]] has to meet to ensure safe, secure and economic proper functioning of the electric system. The facility can be an [[electricity generation|electricity generating plant]], a consumer, or another network.<ref name="GmbH 2019">{{cite web | last=GmbH | first=Next Kraftwerke | title=The Grid Code: Rules for the power network | website=Virtual Power Plant &#124; Power Trader &#124; Aggregator | date=2019-02-13 | url=https://www.next-kraftwerke.com/knowledge/what-is-the-grid-code | access-date=2019-07-04}}</ref>

The grid code is specified by an authority responsible for the system integrity and network operation.

Its elaboration usually implicates network operators (distribution or [[transmission system operatorsoperator]]s), representatives of users and, to an extent varying between countries, the regulating body.<ref name="National Grid ESO 2018">{{cite web | title=Grid Code | website=National Grid ESO | date=2018-10-17 | url=https://www.nationalgrideso.com/codes/grid-code | access-date=2019-07-04}}</ref>

Contents of a grid code vary depending on the transmission company's requirements. Typically, a grid code will specify the required behavior of a connected generator during system disturbances. These include [[voltage regulation]], [[power factor]] limits and [[reactive power]] supply, response to a system fault (e.g. [[short-circuit]]), response to frequency changes on the grid, and requirement to "[[ride through]]" short interruptions of the connection.

There is not a common grid code in all countries and each countryelectric followsgrid has its own grid code. Even in [[North America]], Therethere is no grid code that applies to all territories.<ref name="ABB Conversations 2019"/>

All generators including [[Independent power producer]]s like [[photovoltaic power station]]s or [[wind farm]]s have to comply with the grid code.
