Abstract
Systems and methods for switch-controlled VAR sources coupled to a power grid are described. In some embodiments, a system comprises a distribution power network coupled to a first switch-controlled VAR source. The first switch-controlled VAR source may comprise a processor, a voltage compensation component, and a switch. The first switch-controlled VAR source may be configured to obtain a first delay value, monitor a first proximate voltage, 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, and control, based on the determination, the switch to connect the voltage compensation component to adjust a network voltage or a network voltage component.

11. A method comprising:
-
obtaining, by a first switch-controlled VAR source coupled to a distribution power network, a first delay value that is different from another delay value of another switch-controlled VAR source coupled to the distribution power network; monitoring a first proximate voltage of the distribution power network, the first proximate voltage being proximate to the first switch-controlled VAR source; initiating 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; determining, with a processor of the first switch-controlled VAR source, after the first delay duration, whether to connect a voltage compensation component of the first switch-controlled VAR source based on the monitored voltage, the monitored voltage being possibly changed by the other switch-controlled VAR source; and controlling, based on the determination, a switch of the first switch-controlled VAR source to connect the voltage compensation component to adjust a network voltage or a network voltage component associated with the distribution power network. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A non-transitory computer readable medium comprising instructions executable by a processor for performing a method, the method comprising:
-
obtaining, by a first switch-controlled VAR source coupled to a distribution power network, a first delay value that is different from another delay value of another switch-controlled VAR source coupled to the distribution power network; monitoring a first proximate voltage of the distribution power network, the first proximate voltage being proximate to the first switch-controlled VAR source; initiating 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; determining, with a processor of the first switch-controlled VAR source, after the first delay duration, whether to connect a voltage compensation component of the first switch-controlled VAR source based on the monitored voltage, the monitored voltage being possibly changed by the other switch-controlled VAR source; and controlling, based on the determination, a switch of the first switch-controlled VAR source to connect the voltage compensation component to adjust a network voltage or a network voltage component associated with the distribution power network.
