Abstract

A photovoltaic (PV) plant is normally built in a fixed series-parallel configuration and its power-voltage characteristics often get complex with multiple peaks under partial shading scenarios. Therefore, identification of partial shading is important for monitoring and invoking maximum power pint estimation. This paper proposes a back-propagation neural network (BPNN) based partial shading identification method which locates shaded modules by using measured voltage data. Optimal sensor placement schemes are introduced to decrease the number of utilized voltage sensors, and meanwhile still keep a high identification performance. Experiments are conducted to evaluate the accuracy and effectiveness of the proposed identification method.
