Abstract

The coupling interaction between multiple grid-connected inverters, inverters and grid in the clustered grid-connected distributed photovoltaic (PV) system can cause series and parallel harmonic resonance in the grid. The power quality of grid is seriously affected. Therefore, the resonance problem of the clustered grid-connected distributed PV is urgent to be studied. Aiming at this problem, a resonance analysis model of clustered grid-connected distributed PV system is established in this paper. Besides, the resonance problem of clustered grid-connected distributed PV system during its operation is analyzed. Moreover, a fast resonance detection method based on Wavelet Decomposition is proposed. Finally, simulations verify the effectiveness of the proposed method for the resonance problem of the clustered grid-connected distributed PV system.
