An electric power control system includes an electric power supply system, a load, a power source switching unit, a charge-discharge switching unit, a converting unit, an electric power storage device, a discharge detection unit, a power supply detection unit, and a control unit. The control unit controls the discharge detection unit to detect a state of a first AC power converted by the converting unit from a DC power charged in the electric power storage device, and controls the power supply detection unit to detect a state of a second AC power supplied from the electric power supply system. The control unit regulates the first AC power based on a phase difference between the first AC power and the second AC power, and supplies the first AC power to the load. |
