Abstract

Due to the comprehensive influence of many factors such as performance difference of modules and weather environment, the power prediction technology of DC side of photovoltaic (PV) power station has always been a difficult and important research direction. In this paper, a four-level modelling method of photovoltaic matrix is proposed, which can study the influence of the performance deviation of the PV modules on the output power of the array at any position. Compared with the previous research, this work modelling an independent MPPT unit and numbering each battery in series and parallel components, so as to study the influence of component performance deviation on the overall output power in different circuit positions. At the same time, the function of electrical protection inside and outside the components is considered, which makes the calculation results closer to the actual situation of the power plant. By using this method, the influence of different installation direction of modules on the overall power generation of a 50KW photovoltaic matrix under the same occlusion condition is studied. The results show that when the light intensity loss in the occluded area is less than 40%, there is little difference between the two installation methods; with the increase of the light intensity loss, the power loss of the transverse installation method is smaller.
