Accurate regional distributed PV power forecasting provides data support for power grid management and optimal operation. Distributed PV has the characteristics of large quantity, small capacity and difficulty in obtaining meteorological data. Statistical upscaling method is commonly used to forecast regional power.
Therefore, this paper proposes a short-term regional distributed PV power forecasting method based on sub-region division considering spatio-temporal correlation. Firstly, the representative power plant is selected after dividing the sub-region by the AP clustering algorithm.
The forecasting accuracy of regional PV power depends on the forecasting results of several sub-regions. The sub-regions with similar output characteristics are divided, and then the upscaling weight of the sub-region forecasting data is determined by the sub-region data evaluation score, which can improve the power forecasting accuracy.
Method 1: In each sub-region, a graph network structure is established for plants and representative plant that are highly correlated, and the spatial-temporal correlation between the highly correlated plants and the representative plant within the sub-region is used to forecast the regional short-term PV power generation.
