摘要

An operation schedule generating apparatus generates an operation schedule for controlling a storage battery to discharge electricity when a shortfall in power supply by photovoltaic power generation exceeds a threshold. The operation schedule generating apparatus obtains solar radiation information and a remaining charge of the storage battery; detects a change in the solar radiation information within a predetermined time period preceding a current time; obtains a first candidate corresponding to a first time when the change in the solar radiation information is detected and first solar radiation information and the remaining charge of the storage battery at the first time, and a second threshold candidate corresponding to second solar radiation information and the remaining charge of the storage battery at a second time preceding the first time by the predetermined time period or more, from a storage storing each threshold candidate in association with the remaining charge of the storage battery, the solar radiation information, and a time; selects one of the first candidate and the second candidate, and adjusts the operation schedule based on the selected threshold.
