A Solving Algorithm of Photovoltaic Module Five-Parameter Model
Aiming at Jacobian matrix singularity and parametric drifting problem of photovoltaic module five-parameter model solved with Newton-Raphson method,the Levenberg-Marquardt(LM)algorithm is ap-plied to solve the 5-parameter model parameters of photovoltaic module.Based on actual experimental data anal-ysis of two common modules,analysis results show that the proposed LM algorithm has the advantages of high precision,fast convergence and strong practicability.
