    Volt/VAR Optimization (VVO) optimally manages system-wide voltage levels and reactive power flow to achieve efficient distribution grid operation. VVO assists distribution operators reduce system losses, peak demand or energy consumption using Conservation Voltage Reduction (CVR) techniques.

How reactive power is helpful to maintain a system healthy

    https://electrical-engineering-portal.com/how-reactive-power-is-helpful-to-maintain-a-system-healthy
    Voltage control in an electrical power system is important for proper operation for electrical power equipment to prevent damage such as overheating of generators and motors, to reduce transmission losses and to maintain the ability of the system to withstand and prevent voltage collapse.

VAR Support from Distributed Energy Resources: Preprint

    https://www.nrel.gov/docs/fy04osti/36210.pdf
    The total load (including surrounding small towns) is about 259 MW and 46.4 MVAR. Kern River and Bailey generate 24 MW and 20 MW, respectively. For a wind farm power system, IEC Standard 61 400-21 states that 10- minute average of voltage fluctuation should be within + 5% of its nominal value [5].

Reactive power: what it is; why it is important - DNV GL ...

    https://blogs.dnvgl.com/energy/reactive-power-what-it-is-why-it-is-important
    Increasing var load reduces the ability of the system to deliver real power and perform useful work. In extreme cases, a high var load can shift the voltage and current so much that it reduces the power system’s delivery capability so that almost no active power can be delivered.

Static VAR compensator - Wikipedia

    https://en.wikipedia.org/wiki/Static_VAR_compensator
    A static VAR compensator is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. SVCs are part of the Flexible AC transmission system device family, regulating voltage, power factor, harmonics and stabilizing the system. A static VAR compensator has no significant moving parts (other than internal switchgear).
