Power control system and heat pump system

A power control system comprising:

• an acquisition section that acquires control unit information related to a first limit of a first operation by a control unit provided for a heat pump system that regulates temperature and/or humidity;
• and
• a control section that controls the first operation of the control unit based on the control unit information, wherein
• 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, and the control unit controls apparent power in the power-receiving path,
• the heat pump system receives power from an electrical line of a power distribution system, via a power distribution transformer,
• the control unit is configured to regulate apparent power in the electrical line,
• the control section controls, based on the control unit information, a second operation of the control unit for regulating the apparent power in the electrical line,
• in a case where a first indicator related to the first limit satisfies a preset condition, the control section restricts the second operation of the control unit for regulating the apparent power in the electrical line,
• the preset condition includes a first condition and a second condition different from each other, and
• in response to the first indicator satisfying the first condition and not satisfying the second condition, the control section restricts the second operation for regulating the apparent power in the electrical line and does not restrict a third operation for controlling the apparent power in the power-receiving path, and in response to the first indicator satisfying both the first condition and the second condition, the control section restricts both the second operation for regulating the apparent power in the electrical line and the third operation for controlling the apparent power in the power-receiving path.
