The loss of electricity during transmission cannot be ignored, and a large number power consumers are seeking flexible affordable distributed generation methods to reduce costs. However, photovoltaic (PV) connections pose challenges electric dispatch the security system. Accurate PV forecast can solve these problems, which requires amount accurate historical data build model. This article proposes spatiotemporal interpolation method complement sites. Wavelet packet transform (WPT) is applied decompose original time sequence stable fluctuant sequence. To eliminate fluctuations caused by cloud movement, dynamic warping (DTW) used regularize sequences adjacent Finally, through spatial interpolation, precise obtained. case study shows that under cloudy conditions, proposed reduces NRMSE 0.51% compared direct algorithm.
