Abstract:
1. A system comprising: a distribution power network; a plurality of loads at or near an edge of the distribution power network, each of the plurality of loads configured to receive power from the distribution power network; a plurality of shunt-connected, switch-controlled VAR source at the edge or near the edge of the distribution power network, each of the plurality of shunt-connected, switch-controlled VAR sources configured to detect a first proximate voltage at the edge or near the edge of the distribution power network, each of the plurality of shunt-connected, switch-controlled VAR sources comprising a first processor and a voltage compensation component, the processor configured to enable the shunt-connected, switch-controlled VAR source to determine, after a delay, whether to enable the VAR compensation component based on the first proximate voltage to adjust voltage volt-ampere reactive by controlling the VAR compensation component based on the determination; and a plurality of harmonic management blocks coupled to the distribution power network, each harmonic management block comprising a resonance detection module and a resonance compensation component, each harmonic management block configured to compare a second proximate voltage to at least one resonant threshold to detect potential resonance caused by enablement of the voltage compensation component of at least one of the plurality of shunt-connected, switch-controlled VAR sources, and to engage based on the comparison the resonance compensation component to manage the potential resonance.
