Abstract :
Typically the resonance problems related to the use of LCL-filters in grid connected inverters are analyzed assuming the operation of a single inverter. Wind and photovoltaic parks may experience propagation of resonance from a poorly damped inverter to other systems connected in parallel. The paper focuses on the study of the resonance at a park system level with simulations and experimental results.
