Abstract :
The control of power electronic converters is subjected to several challenges as measurement sensors drift, malfunction in harsh environments, non-ideal grid, and performance degradation due to the delay of discrete control systems. In this paper, a stationary frame resonant current controller for inverter-based distributed generation (IBDG) with sensor-less grid voltage operation is proposed. The delay sources are taken into account and compensated. The proposed approach is simulated through Matlab/Simulink and verified experimentally.
