A Review on Photovoltaic Power Forecasting Technics

Abstract

A review of photovoltaic (PV) power output forecasting technology is presented based on the latest information in the literature. In addition to short-term ahead prediction and day ahead prediction techniques using numerical weather prediction models, the challenges of forecasting techniques caused by factors other than weather forecasting (dust and snow) are discussed. Uncertainties in forecasts using ensemble forecasting are also discussed. Case studies are presented on the impact assessment of various solar power forecasts. It also introduces the available data for climate change adaptation in anticipation of future climate change. In addition, the trends of related projects to improve forecasting technology in Japan and abroad are described. The challenges of PV output forecasting technology are itemized.
