A photovoltaic (PV) power system data reconstruction method based on subset partial least squares (PLS)

In this paper, a data reconstruction method was proposed to reconstruct the missing current data of a panel string of a PV power system. Two training sets and one evaluation set from a practical PV power system were used to build and evaluate the original PLS data reconstruction model. To increase the accuracy of data reconstruction model, a subset PLS model was built and evaluated using the evaluation set. Results indicates the proposed method can increase the accuracy of data reconstruction effectively.
