Abstract: A power control system controlling a demand-supply balance of electric power in a distribution network by controlling charge/discharge operations of storage batteries of a plurality of vehicles connected to the distribution network, includes a control unit, which creates a charge/discharge operation plan of the storage batteries within a predetermined period using a power supply and demand plan of the distribution network within the predetermined period and vehicle information indicating states of the vehicles within the predetermined period, extracts time and a point at which a voltage of the distribution network is not within a predetermined range using the charge/discharge operation plan of the storage batteries, creates a reactive power control plan for injecting reactive power at the extracted time and point to keep the voltage of the distribution network within the predetermined range, and controls the reactive power according to the created reactive power control plan.
