Research on Engineering Analytical Model of Solar Cells
摘要
Abstract
As the output characteristic curve of photovoltaic(PV) cell is the theoretical basis of PV Power.This paper starts from studying the similarity between the output characteristic curve of PV cell and the trajectories of the horizontal projectile motion.Also based on the original project index model of PV cell,this paper first proposes a new engineering mathematical model which is easier to calculate in practice.The characteristic of the new model is that it attempt to indirectly analyze the trajectories of the horizontal projectile motion under three different gravity g0,g1 and g2 instead of directly analyzing the output characteristic curve of PV cell.Using the horizontal projectile motion formula to carry out the conversion formula of output characteristic curve of PV cell,then through adjusting the demarcation points of g0 and g1,to make the error near the maximum power point(MPP),under varying environmental conditions,as small as possible.By comparing the measured data,it shows this model can meet the engineering requirement.What's more,this new model reduces the computational complexity and improves the operation speed comparing with the original project index model.关键词
