DIGITAL CONTROL DESIGN SCHEME FOR AN LCL-TYPE INVERTER BASED ON QPR CONTROLLER WITH GVWF UNDER WEAK GRID CONDITIONS

Digital Control Design Scheme for an LCL-Type Inverter Based on QPR Controller With GVWF Under Weak Grid Conditions

This paper introduces a digital control strategy for an inverter with an LCL filter that can be used in weak power grids.Due to the effects of digital control delays and the influence of grid voltage and impedance in a weak power grid (WPG) on the inverter system, it is easy for the system to oscillate, distort the output current, or even read more
