Abstract

A novel maximum power point tracking (MPPT) algorithm is proposed in this paper based on the linear iteration method for photovoltaic (PV) power generation for improving steady-state performance and fast dynamic response simultaneously. In this MPPT algorithm, linear prediction estimates the MPP of PV with a very high accuracy due to the constant-voltage and constant-current characters of PV. Then, further iterations for error correction are executed to get a better approximation to the MPP. Experiments verify theoretical analysis and demonstrate its fast dynamic response and high working efficiency.
