Short-term Power Forecasting of Distributed Photovoltaic Station Clusters Based on Affinity Propagation Clustering and Long Short-term Time-series Network
To cope with the challenges brought by the increasing penetration rate of distributed photovoltaic to power grid operation
a short-term power forecasting model of regional distributed photovoltaic station clusters based on affinity propagation clustering and long short-term time-series network (LSTNet) is proposed. First
the affinity propagation algorithm is employed to divide the regional distributed photovoltaic station clusters into different seasons. Pearson correlation coefficient is used to determine the strong correlation between meteorological factors of photovoltaic output
and the bilinear interpolation method is utilized to encrypt the meteorological data of the corresponding photovoltaic station cluster. Furthermore
LSTNet is used to mine the long-term and short-term temporal and spatial dependence of photovoltaic power and meteorological factor series
and linear components of autoregression are superimposed to realize the simultaneous forecasting of multiple photovoltaic stations in the group. Finally
the effectiveness of the proposed method is verified on the measured data set from the National Renewable Energy Laboratory (NREL) of USA. The experimental comparison shows that the forecasting model obtains high forecasting accuracy and robustness.
