Abstract
As for the equivalent module and output characteristic curve of photovoltaic cell of single phase two level photovoltaic power generating system
in this paper
the maximum power point tracking method is discussed
a kind of photovoltaic MPPT control technology based on fuzzy control is proposed and constant voltage method is adopted in the start-up period. It can be proved by the modeling and simulation that the MPPT control technology
combined by the two methods
can improve the response speed while assuring the steady accuracy of system and achieve smooth transition.
