Reactive power cannot be transmitted over a long distance or through power transformers due to excessive reactive power losses. Reactive power supply should be located in close proximity to its consumption. Sufficient static and dynamic voltage support is needed to maintain voltage levels within an acceptable range.

Reactive power loads must be supplied either locally from customer-owned devices or from the system itself. It is almost universal for some of the reactive load to be compensated locally as power-factor correction. Power factor is a measure of the relation between real and reactive power. The power factor ranges from 0.0 to 1.0, where 1.0 means ...

Critically, real power is what is compensated in RTO wholesale electric markets. Thus, when generators are ordered by system operators to generate or absorb reactive power to support voltage, they trade off their ability to generate real power and earn RTO market revenues.

Provision of voltage support that exceeds the minimum technical requirement of the obligatory reactive power service (ORPS). Find out more 14 October 2019 - We invite transmission or distribution connected providers to tender for the provision of a Reactive Power Service in the Mersey region from April 2020 - …
https://en.wikipedia.org/wiki/Volt-ampere_reactive
In electric power transmission and distribution, volt-ampere reactive (var) is a unit of measurement of reactive power.Reactive power exists in an AC circuit when the current and voltage are not in phase. The term var was proposed by the Romanian electrical engineer Constantin Budeanu and introduced in 1930 by the IEC in Stockholm, which has adopted it as the unit for reactive power.

Transmission connected generators are generally required to support reactive power flow. For example, on the United Kingdom transmission system, generators are required by the Grid Code Requirements to supply their rated power between the limits of 0.85 power factor lagging and 0.90 power factor leading at the designated terminals.

Feb 14, 2018 · When it comes to the dispatchable reactive power that can be provided by the distribution system, the net values attributed to the transmission buses should be considered. This value differs from the available reactive power support by the DERs and other sources of reactive power.

Sep 27, 2019 · (1) Volt-ampere reactive ("var") is a unit by which reactive power is expressed in an alternating current ("AC") electric power system. Reactive power exists in an AC circuit when the current and voltage are not in phase. In an electric transmission system, reactive power serves to support the voltage levels needed to maintain system reliability.

economic benefits of delivering additional reactive power support in Victoria. In May 2018, AEMO published a Project Specification Consultation Report (PSCR)2, which identified the need for up to 800 megavolt amperes reactive (MVAr) of additional reactive support by 2028 to maintain voltages within operational design limits.
