VSCs connected to the grid through LCL filters are common in the integration of renewable energies into electrical systems. Therefore, in this paper small signal stability of the current loop of this configuration is performed. The analysis includes the getting of a state-space representation of the system, the calculation of their eigenvalues and the sensitivity analysis to the variation of some relevant parameters. Real-time simulations have also been carried out in order to validate the theoretical analysis.
