摘要
Abstract
According to the topology of double-stage photovoltaic grid-connected inverter,a control method based on double closed-loop control is designed.The front stage of the system realizes the photovoltaic maximum power point tracing(MPPT)control.Back stage controls DC bus voltage stability,while AC grid connection.This control method can better take into account the photovoltaic MPPT effect,the dynamic characteristics of the grid-connected inverter and the stability of the system.Firstly,it summarizes and ana-lyzes the research of the photovoltaic grid-connected inverter,and expounds the structural characteristics of the two-stage photovoltaic grid-connected inverter.Then,it respectively explains and analyzes the MPPT control method,grid-connected control method and in-verter controller design of this system.Finally,it builts a system simulation model in the PLECS simulation software,and the simula-tion verifies the correctness and effectiveness of the double-stage photovoltaic grid-connected inverter control method designed.关键词
