Photovoltaic Panel Deployment of Large-Scale Photovoltaic Power Plant Based on Meteorological and Topographical Factors

Developing and utilizing photovoltaic (PV) resources in accordance with local conditions is one of the effective methods to help power system reduce carbon. The paper discloses a PV panel deployment optimization method in large-scale PV power plants (PVPPs), including dividing the PVPP into multiple regions according to the topographical characteristics; based on the LSTM model with attention mechanism, forecast the PV power generation; eventually, the PV panels in the PVPP are deployed. When dividing the different regions in the PVPP, a variety of topographical features to reasonably divide each block into several regions. Then the effect of meteorological factors on the PV power generation in each region is quantified, to obtain a more precise value of PV power generation. The deployment of PV panels maximizes the use of existing PV resources, and increases effectiveness of PV output.
