Abstract EN
The output power of PV array changes with the variation of environmental factors, such as temperature and solar irradiation.
Therefore, a maximum power point (MPP) tracking (MPPT) algorithm is essential for the photovoltaic generation system.
However, the P - U curve changes dynamically with the variation of the environmental factors; here, the misjudgment may occur if a simple perturb-and-observe (P&O) MPPT algorithm is used.
In order to solve this problem, this paper takes MPPT as the main research object, and an improved MPPT algorithm for PV generation applications based on P - U curve reconstitution is proposed.
Firstly, the mathematical model of PV array is presented, and then the output dynamic characteristics are analyzed.
Based on this, a P - U curve reconstitution strategy is introduced, and the improved MPPT algorithm is proposed.
At last, simulation and comparative analysis are conducted.
Results show that, with the proposed algorithm, MPP is tracked accurately, and the misjudgment problem is solved effectively.
