A Comparative Study of Central and Grouped and Distributed MPPT Architectures for Power Generation Efficiency of Photovoltaic System
There are three different MPPT architectures in photovoltaic system:central
grouped and distributed architecture
and their power generation efficiencies are researched respectively.The simulation results show that the annual generation capacity of photovoltaic system with distributed MPPT architecture can be increased up to 4.65%~19.62% compared to system with central MPPT
and 2.64%~12.86% compared to system with grouped MPPT.The actual efficiency increasement varies with the proportion of time partial shading and the degree of module parameter mismatch
and is independent of specific shadow mode respectively
