**5. Results**

The real-time simulation results obtained through the implementation of the proposed PLL-less PVMT-based FLDPC method for PV-VSI of grid-tied MG are presented in this section. The real-time simulations were carried out on RTDS, and the laboratory setup to validate the performance of the proposed power controller is shown in Figure 6.

Two case studies were conducted in this study to validate the performance of the proposed power controller. For the first case study, the steady-state and transient response of the proposed controller for PV-VSI was validated by changing both real and reactive power references, and by changing only real power references. The results were compared with those of the conventional PLL-PI-integrated dq CCS-based control method, proposed in [6]. For the second case study, load demand and solar irradiation were varied to test the proposed controller performance during MG's different operating modes. Finally, a comparative study was conducted to prove the preeminence of the proposed FLDPC method.
