摘要

本文是一项为期一年的韩国昌原光伏发电量日前预测案例研究。本文重点关注日前每小时光伏发电量预测和长期实验。我们介绍了三种基于机器学习的预测方法,这些方法可预测次日午夜的每小时光伏发电量,并展示了这些方法在昌原 51 kW 光伏系统中一年的性能表现。我们的方法学习历史气象因素的关系,然后根据训练的关系和气象预报机构的天气预报预测 24 小时的光伏发电量。我们展示了所有建议方法和一个持续模型一年的月度性能。由于韩国地处温带,四季分明,气候特征复杂,因此很难通过短期实验结果显示光伏预测方法的实际性能。我们相信,本文的长期实验结果将为下一步研究提供宝贵数据。

Day-Ahead Prediction of PV Power Output: A One-Year Case Study at Changwon in South Korea

Day-Ahead Prediction of PV Power Output: A One-Year Case Study at Changwon in South Korea

This paper is a one-year case study of day-ahead prediction of PV output at Changwon in South Korea. We are focused on day-ahead hourly PV power forecasting and long-term experiments in this paper. We introduce three machine learning based forecasting methods that predict hourly PV power for the next day at midnight, and show performance of them for a 51 kW PV system located at Changwon for a year. Our methods learn relationship of historical meteorological factors, and then predict 24 h PV power considering the trained relationship and weather forecasts from weather forecasting organizations. We show monthly performance of all the proposed methods and a persistence model for a year. Since South Korea is located in a temperate zone with four distinct seasons, and has complex climate characteristics, it is difficult to show actual performance of PV forecasting methods by short-term experimental results. We believe that long term experimental results in this paper are valuable data for the next studies.
