3.2. Demand Forecast Analysis according to Hourly Power Demand and Temperature Compensation
Figure 2. Forecasting demand based on hourly power demand and temperature correction
For demand forecast analysis according to hourly power demand and temperature compensation,
system is designed to predict available photovoltaic power by collecting data on solar radiation and
cloud amount from weather forecast data and performing similarity filtering comparison between
forecast data and actual weather data.
Group patterns are filtered by collecting the load data in the derived information and, based on
the KEPCO electricity tariff system, classifying them by season and then segmenting them into
weekdays and weekends.
Similar weather data are extracted for further correction of collected data, and hourly power
demand prediction is derived from the data average value.
