Single-phase Photovoltaic Grid-loop Control Strategy Based on LCL Filter
摘要
Abstract
Based on LCL filter instead of L and LC type filter,through active damping algorithm,in response to the DC bus overvoltage phenomenon due to the mismatching of input and output power when the light is too strong ,this paper proposes the loop control strategy of DC bus voltage loop,current loop power and capacitor current loop in order to stabilize DC bus voltage. A single-phase photovoltaic grid control system model is estab-lished and a detailed analysis of the design of the control strategy is carried out. The simulation results show that the new control strategy can effectively control the DC bus voltage,improving current quality and system stability.关键词
