基于优化奇偶重构法的光伏阵列自适应重构技术设计
Design of Adaptive Reconfiguration Technique for PV Arrays based on Optimized Odd Even Configuration Method
摘要
Abstract
For PV arrays,shading and array fault can lead to a reduction in their output power.To en-hance the output power of PV arrays,this paper proposes the optimized Odd Even Configuration(OOEC)method,which corrects the disadvantage of the poor reconfiguration effect of the Odd Even Configuration(OEC)when the local shading exceeds 4 columns.The proposed method in this paper divides the PV ar-rays into a free reconfiguration module and a fixed reconfiguration module and adjusts the connection method according to different shading situations to determine the optimal connection relationship.The simulation experiments are compared with the three methods of the Arrow So Du ku,Zig-zag,and OEC.The simulation results show that the output power of the PV array after OOEC reconfiguration is signifi-cantly improved,and the PU output curves of the PV arrays tend to be more single-peaked and by mis-match loss,power enhancement,performance ratio,and equalization index,OOEC seems to have better performance.关键词
