Operation planning method, and heat pump hot water supply and heating system operation method
First Claim
1. An operation planning method performed in a system including a power generation device, a first electric load which operates using power generated by the power generation device, and a second electric load which generates heat using power generated by the power generation device, the second electric load including a heat generation unit which generates heat using power generated by the power generation device, a heat storage unit which stores heat generated by the heat generation unit, a first radiator unit which radiates heat stored in the heat storage unit, and a second radiator unit which directly radiates heat generated by the heat generation unit, said operation planning method being performed to design an operation plan for the second electric load, and said operation planning method comprising:
- predicting, for individual unit time periods, an amount of power to be generated by the power generation device, a first amount of power to be consumed by the first electric load, and a second amount of power to be consumed by the heat generation unit to generate heat to be radiated by the second radiator unit; and
designing the operation plan for the second electric load to cause the second electric load to operate during an operation period which includes, among the unit time periods, a unit time period in which an amount of reverse power is the largest, the reverse power being calculated by subtracting the first amount of power to be consumed and the second amount of power to be consumed from the amount of power to be generated.

Abstract
An operation planning method performed in a system including a power generation device, a first electric load operating using power generated by the power generation device, and a second electric load which generates heat using power generated by the power generation device. The operation planning method is performed to design an operation plan for the second electric load and includes: predicting, for individual unit time periods, a power generation amount by the power generation device and a power consumption amount by the first and second electric loads; and designing the operation plan for the second electric load to operate during an operation period including the time period with the largest amount of reverse power, calculated by subtracting the first and second power consumption amounts from the power generation amount.
