Operation planning method, and heat pump hot water supply and heating system operation method

摘要

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.
