Abstract

A heat pump operation method includes: obtaining, on a per time unit basis, an amount of the power generated by the power generation device, an amount of the power consumed by the electric load, and surplus power which is a difference between the generated power and the load power; and controlling operation of the heat pump to cause the heat pump to generate heat using power adjusted to follow a per time unit increase or decrease in the surplus power. In the controlling, when an amount of change in the surplus power remains greater than a predetermined threshold value for a given period of time extending back from a present time, an extent to which the power consumed by the heat pump follows the surplus power is reduced.
