Abstract
With increasing penetration of renewable energy sources into modern power systems, multiparallel inverters are commonly employed in the interface to the utility grid, giving rise to potential resonance problems. In order to better understand the issue, resonance of multiparallel inverters is analyzed under an asynchronous carrier. First, multiparallel inverter equivalent circuits are modeled within a controlled bandwidth. In order to investigate resonance characteristics under an asynchronous carrier, a crossover filter function is used to separate output currents of different frequencies for a two-parallel inverter to analyze the output current frequency response. With this approach, resonance characteristics are focused under asynchronous conditions, and the impact of shifting LCL parameters on resonance is examined. The influence of paralleled inverter number on output currents is examined, and the analysis is expanded to multiparallel inverter systems to determine the resonance characteristics. Experimental results validate the developed models and the proposed resonance characteristics.
