Grid-connected control research of distributed photovoltaic connected to AC distribution network
Proceeding of the 11th World Congress on Intelligent Control and Automation, 2014A lot of harmonic is generated when distributed photovoltaic (PV) connects to the distribution network through inverter. LCL filter is adopted in the grid-connected control system because LCL filter has stronger ability to filter high frequency harmonic than L-type filter. Compared with pulse width modulation (PWM), space vector pulse width modulation (

Influence of grid-connected inverters on the power quality of the distribution grid
2014 International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2014Many inverters are quoted as having a PF of better than 0.95 when in reality, the true power factor is between 0.5 and 0.75. This paper describes the influence of grid-connected inverters on the distribution grid. The impact of the voltage distortion from the inverter to the distribution grid is relative small without grid impedance.

Predicting Resonance Frequencies in Distribution Networks with Grid-Connected Inverters
2022 20th International Conference on Harmonics & Quality of Power (ICHQP), 2022Increase in the amplitude of current harmonics at a resonance frequency could lead to high voltage harmonics in the distribution network due to resonance. As these voltage harmonics could potentially damage the insulation of network elements, preventive actions need to be taken.

A testing platform for distribution grid with multiple grid-connected converters
2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016Distributed renewable energy generation units with medium-voltage distribution grid integration are considered as the most effective utilization manner because of low cost. However, the medium-voltage level (typically reach to 50 kV) brings safety risks in the experimental debugging process of new circuit topologies and algorithms for medium-voltage ...
