Development of photovoltaic arrays model for maximum power point tracking simulation

It is important to evaluate a maximum power point tracker (MPPT) under the same conditions. However, under the natural conditions, insolation, temperature and the power converter may influence the evaluation. Therefore, a simulation that makes the same condition is required. In our previous simulation, the whole I-V characteristics are made every 0.01 [s] based on the measured insolation data every 1 [s] with linear interpolation to perform the stepped I-V characteristics. In this paper, the simulation program which can shorten calculation time compared to the previous version by calculating a partial I-V characteristic around the operating point is proposed.
