Abstract
A voltage monitoring control device includes: a transceiver unit communicating with local voltage control devices adjusting a control amount of voltage control apparatuses that control a voltage on a power distribution line in a high-voltage system every second cycle based on a command value updated every first cycle; an indicatable-range updating unit determining an indicatable range, which is a range of reactive power indicatable to the local voltage control device, based on a control result received via the transceiver unit from the local voltage control device that controls a reactive-power-modified voltage control apparatus, the control result being a limit-value time or a limit-value-time ratio; and a reactive-power determination unit determining a reactive-power command value, which is a command value updated every first cycle based on the indicatable range and transmitted, via the transceiver unit, to the local voltage control device that controls the reactive-power-modified voltage control apparatus.
