Abstract

This paper investigates the influence of the grid-connected renewable energy sources and their effect on the utilities having diode front-end rectifiers. The grid interface in the renewable energy converters generally has PWM Inverters with LCL filters. These LCL filters are tuned for different resonance frequencies based on their switching frequency and system parameters. With multiples of renewable energy source converters connected in parallel, the grid parameters and harmonic interaction change differently based on the individual LCL filter design and operating conditions. This condition becomes worse if inverters connected in the same PCC are significantly increased. The utility rectifiers are designed for a specific range of grid specification according to various international standards. Effect of grid parameter variation such as voltage and current harmonic injection due to these inverters in a specific grid configuration and application from earlier studies is referenced. Grid model is generated from earlier studies and simulation was carried out for a specific diode front-end model of VFD. Reliability variation in front-end rectifier utilities such as variable frequency drives with a special emphasis on DC filter capacitor and DC link inductor is also discussed.
