摘要

本研究应用谐波模型来预测每月高峰日的日负荷曲线。采用谐波模型捕捉日负荷的周期性规律,避免了对天气敏感参数的依赖。谐波模型是基本负荷、小时负荷和傅立叶级数的函数。该数据集来自泰国省电力局2008-2012年的负荷研究数据。结果表明,五次谐波模型能较好地预测月峰日的负荷曲线。对不同的电价表进行预测,以比较住宅、商业和工业用户的负荷模式。

Forecasting of daily load curve on monthly peak day using load research data and harmonics model
This work applies a harmonics model to forecast a daily load curve on a monthly peak day. The harmonics model is applied to capture periodic pattern of daily load and to avoid relying on weather-sensitive parameters. The harmonics model is a function of a base load, an hourly load, and a Fourier series. The dataset was obtained from load research data over the year 2008–2012 from the Provincial Electricity Authority of Thailand. It was found that the fifth harmonic model is proper to forecast the load curves on the monthly peak day. The forecasts of different tariff schedules are performed to compare the load patterns of residential, commercial, and industrial customers.
