Abstract

Most of the distributed generation (DG) systems utilise power electronic converters for interfacing with the grid. Increasing the number of power electronic devices, including DG with electronic converters, in the network has contributed to a harmonic problem. Although the integration of a passive filter within inverter based DG units can reduce the harmonic distortion, they also have a negative effect due to the resonance phenomenon. Thus, this paper aims to analyse the impact of inverter based DG on resonance and harmonic distortion. The analysis was performed for an inverter based DG system connected to the IEEE 13 bus distribution test system. To investigate resonance phenomenon, frequency scan was conducted while the fast Fourier transform analysis was carried out to measure the voltage and current distortion at the point of the common coupling and the DG connected bus. The test system was simulated using MATLAB/SimPowerSystems, and the results show that there can be resonance phenomenon and harmonic distortion due to the interaction of the inverter based DG and grid impedance. Moreover, the results also indicate that the maximum permissible penetration level of inverter based DG in the tested distribution system is 40% of total load. This study might be useful for utilities to plan the integration of DG units in the distribution system to avoid the resonance phenomenon and harmonic distortion.
