Abstract:

Due to the uneven distribution of terrain and aging of photovoltaicmodules, the mismatch loss problem of PV modules has became increasingly prominent. For large ground and mountain power stations, in order to solve these problems, the multi-channel maximum power point tracking (MPPT) technology of inverter will become an inevitable trend. In this paper, Simulink is used to simulate the photovoltaic power generation system,and the comparison between the distributed and the traditional centralized is carried out to verify the superiority of the distributed MPPT efficiency.

Key words: Distributed inverter, photovoltaic inverter, multi-channel MPPT, photovoltaic power generation system simulation
