Support Vector Quantile Regression for the Post-Processing of Meso-Scale Ensemble Prediction System Data in the Kanto Region: Solar Power Forecast Reducing Overestimation
Autor: Takahiro Takamatsu, Hideaki Ohtake, Takashi Oozeki
Publikováno v: Energies, Vol 15, Iss 4, p 1330 (2022)
Although the recent development of solar power forecasting through machine learning approaches, such as the machine learning models based on numerical weather prediction (NWP) data, has been remarkable, their extreme error requires an increase in the

Solar Irradiance Forecasts by Mesoscale Numerical Weather Prediction Models with Different Horizontal Resolutions
Autor: Hideaki Ohtake, Fumichika Uno, Takashi Oozeki, Syugo Hayashi, Junshi Ito, Akihiro Hashimoto, Hiromasa Yoshimura, Yoshinori Yamada
Publikováno v: Energies, Vol 12, Iss 7, p 1374 (2019)
This study examines the performance of radiation processes (shortwave and longwave radiations) using numerical weather prediction models (NWPs). NWP were calculated using four different horizontal resolutions (5, 2 and 1 km, and 500 m). Validation re

Outlier Events of Solar Forecasts for Regional Power Grid in Japan Using JMA Mesoscale Model
Autor: Hideaki Ohtake, Fumichika Uno, Takashi Oozeki, Yoshinori Yamada, Hideaki Takenaka, Takashi Y. Nakajima
Publikováno v: Energies, Vol 11, Iss 10, p 2714 (2018)
To realize the safety control of electric power systems under high penetration of photovoltaic power systems, accurate global horizontal irradiance (GHI) forecasts using numerical weather prediction models (NWP) are becoming increasingly important. T
