  • Patent number: 10963602
    Abstract: An actual power generation amount receiver acquires an actual power generation amount of a photovoltaic power generation system of each time slot of each day. An extraterrestrial solar radiation calculator calculates an extraterrestrial solar radiation of each time slot of each day at a disposition position. A weather information receiver acquires an actual weather record of each time slot of each day and a weather forecast of a prediction target time slot. A similar date extractor classifies a time slot, which is the same as a prediction target time slot of each day in a search range in which an actual power generation amount is acquired, as a similar time slot for each actual weather record type. A prediction formula deriver derives a power generation amount prediction formula for calculating a predicted power generation amount based on an actual power generation amount.
