Hour-Ahead Photovoltaic Power Forecasting Using an Analog Plus Neural Network Ensemble Method
2020
Energies
Preserved Fulltext
In this paper, a methodology for one-hour-ahead PV power forecasting is proposed. ...
The common analog approach and ensemble methods in photovoltaic (PV) power forecasting are based on the forecasts from several numerical weather prediction (NWP) models. ...
Based on the forecast horizon, PV power forecasting methods can be divided into the following categories: very-short-term (i.e., few seconds to hours ahead), short-term (i.e., one to three days ahead), ...
