Abstract

Recently, many people in the world pay attention to the renewable energy and a photovoltaic system becomes especially worthy for the future of the earth. In this paper, we investigate the operation of PV system with storage battery by using next-day residential load forecast. First, we propose the application of a simple and high-precision modeling method, i.e., Just-In-Time Modeling to the forecast of residential load. And we carry out the improvement in predictive accuracy by the input selection and the weighting method. Next, we simulate the operation of PV system with storage battery by using the load forecast information. The result shows that the introduction of load forecast into PV system operation contributes to environmental conservation and reduction of operating cost.
基于次日居民负荷预测的蓄电池光伏系统运行设计
最近,世界上许多人都在关注可再生能源,光伏系统对地球的未来变得尤为值得关注。本文采用次日居民负荷预测的方法,对带蓄电池光伏发电系统的运行进行了研究。首先,我们提出了一种简单、高精度的建模方法,即即时建模(Just-In-Time modeling),用于住宅负荷预测。并通过输入选择和加权法来提高预测精度。其次,利用负荷预测信息,对带蓄电池的光伏发电系统进行了运行模拟。结果表明,在光伏发电系统运行中引入负荷预测,有利于环境保护和降低运行成本。
