Title: SCHEDULING-BASED DISTRIBUTION LINE VOLTAGE CONTROL METHOD AND SYSTEM
Abstract:
The present invention relates to a scheduling-based distribution line voltage control method comprising: a line voltage minimization step of receiving a predicted load value and a predicted power generation amount of a distribution line, with which distributed energy resources are connected, for each time period, and calculating control command values for a reactive power control device and a tap control device for controlling the voltage of the distribution line such that the same has a minimum value; and a tap control device operation plan derivation step of repeatedly performing the control command value calculation step for each predetermined time interval so as to calculate a tap operation schedule of the tap control device. The present invention can always expand and accommodate distributed energy resources and can maintain a distribution line voltage at an appropriate level.
