POWER CONTROL SYSTEM AND HEAT PUMP SYSTEM

[Object] On the basis of a limit of an operation of a control unit that is connected to a power-receiving path of a converting unit, is electrically parallel with the converting unit, and controls apparent power in the power-receiving path of the converting unit, the operation of the control unit is controlled. [Solution] A power control system includes: an acquisition section that acquires control unit information related to a limit of an operation by a control unit provided for a heat pump system that regulates temperature and/or humidity; and a control section that controls an operation of the control unit on the basis of the control unit information. The control unit is connected to a power-receiving path of a converting unit that converts received power and supplies the converted power to a load used for the regulating. The control unit is electrically parallel with the converting unit. The control unit controls apparent power in the power-receiving path.
