Abstract

As for the power quality issue of public grid connection point

type LCL grid connected inverterwith harmonic and reactive power real time compensation function is proposed. The instantaneous reactivepower theory is taken as base

the decoupling separation for active and reactive component is performedthrough abc-dq coordinate transformation and a kind of method which can perform real time tracking loadharmonic and reactive power is designed. With comprehensive consideration of multiple functions of gridconnected inverter

the instability factor of LCL filter system is analyzed and the limit condition of its pa-rameters is discussed. The simulation experiment of LCL grid connected inverter is set up in Matlab

whichproves the correctness of real time compensation harmonic

reactive power and parameter design of LCL.
