| Abstract: | Part of the panels of photovoltaic systems by the shadowing caused by the series and parallel mismatch can seriously affect the generation capacity.A power optimization connect to each panel can effectively solve the problem.This paper discussed the architecture of distributed PV systems,analyzed the different topology structure of the DC-DC converter as distributed optimizer characteristics and applicability.Finally,the efficiency and improvements of the PV optimization are discussed,and the results are verified by Simulink simulation. |
