A Calculation Method of Photovoltaic Array's Operating Point for MPPT Evaluation Based on One-Dimensional Newton-Raphson Method

Comparison and evaluation of maximum power point tracking (MPPT) algorithms for photovoltaic (PV) arrays are often carried out by computer simulation because any irradiation and temperature condition can be set up and repeated. This paper proposes a new simple calculation method for computer simulat...

Description
Summary:Comparison and evaluation of maximum power point tracking (MPPT) algorithms for photovoltaic (PV) arrays are often carried out by computer simulation because any irradiation and temperature condition can be set up and repeated. This paper proposes a new simple calculation method for computer simulation to evaluate any MPPT algorithm. The proposed method rapidly calculates the operating point of the PV array. The 1-D Newton-Raphson method is repeated, instead of expanding this method, in multidimensional cases. The proposed method is compared with the conventional combination methods. We confirm the adequate accuracy and short calculation time of the proposed method.
