Operational Security |
European Union Electricity Market Glossary | ||||
Operational security is the transmission system's capability to retain a normal state or to return to a normal state as soon as possible, and which is characterised by operational security limits (Article 3(1) of the Network Code on System Operation).
Where the level of reactive power ancillary services is not sufficient for maintaining operational security, Transmission System Operators (TSOs) prepare and activate remedial actions (Article 109(3) of the Network Code on System Operation).
In such a case the TSO informs the neighbouring TSOs.
According to the Network Code on Network Operation each TSO is required to publish the levels of reserve capacity necessary to maintain operational security.
