A Method to Consider Voltage Distortion Caused by Interaction Grid-Connected Inverter and Distribution System

Voltage distortion of 2 kHz to 9 kHz may occur in the distribution line due to resonance in the system, and the generation conditions and mechanism have been revealed. For frequencies below 2 kHz, it is desirable to analyze the cause of voltage distortion anew due to the widespread use of grid-connected inverters. This paper shows a method to consider voltage distortion caused by interaction grid-connected inverters and distribution systems.
