| Abstract | ||
| The work is based on improving the line regulation and minimizing the THD for the inverter voltage at the connected bus to the microgrid (MG). These objectives have been verified in this study under operating conditions with different types of loads disturbances. The control technique for THD minimization and voltage regulation enhancement is obtained using the tripled actions controller (TAC). This controller combines a PR (Proportional Resonant) controller with SHC (Secondary/Secondary Hybrid Control) and introduces a third controller for the PWM of the voltage obtained from the inverter. Voltage regulation is adjusted applying the FOPID controller, so the bus voltage and the operating frequency will be restored at their rated values. To verify the optimization for this objectives, the study employed PSO method to find the optimum solution. Comparison is done with previous published work, which illustrated that the proposed system outperformed the others with respect to voltage waveform, frequency deviation, and THD. Also, the developed control technique verifies improved power quality issues (PQ) and increased the reliability of power system when supplying different load types. | ||
