1. A system comprising:

  • a distribution power network;

    a first switch-controlled VAR source coupled to the distribution power network, the first switch-controlled VAR source comprising a processor, a voltage compensation component, and a switch, the first switch-controlled VAR source configured toobtain a first delay value that is different from another delay value of another switch-controlled VAR source coupled to the distribution power network,monitor a first proximate voltage of the distribution power network, the first proximate voltage being proximate to the first switch-controlled VAR source,initiate a first delay duration based on the comparison of the first proximate voltage to at least one set point, the first delay duration being based on the first delay value,determine, with the processor, after the first delay duration, whether to connect the voltage compensation component based on the monitored voltage, the monitored voltage being possibly changed by the other switch-controlled VAR source, andcontrol, based on the determination, the switch to connect the voltage compensation component to adjust a network voltage or a network voltage component associated with the distribution power network.
