**5. Simulation and Analysis**

In this section, we prove the proposed TFRT algorithm and control method by conducting a simulation and analyzing the results. Substation, PCS-based DG, load, and controllers were modeled through the PSCAD/EMTDC software package and the simulation was conducted according to the scenario set up to verify the continuous operation of DGs during temporary fault and restoration.

### *5.1. Configuration of Distribution Systems with DGs and Loads*

The system configuration is shown in Figure 8, with the substation, distribution line, PCS-based DG, and loads. In addition, specific information on each model is summarized in Table 2. In the case of a renewable energy source, a model composed of a current controller is applied using the d–q-axis current value for MPPT (Maximum Power Point Tracking). The load is considered as constant impedance and is distributed equally in consideration of the length of the distribution line.
