*5.3. Simulation Scenarios*

To evaluate our proposed mathematical model for optimal location and sizing of PV sources in DC grids, we consider that the size of these generators can be 60% of the total demand in the peak hour; i.e., 332.4 kW. In addition, we consider four simulation cases as follows: **<sup>S</sup>**1) as the base case of the test system without including PV sources, **<sup>S</sup>**2) as the location of one PV source, **<sup>S</sup>**3) as the location of two PV sources and **<sup>S</sup>**4) as the location of three PV sources inside of the DC system. The main idea of these scenarios is to evidence the effect of having a total PV installation capacity distributed in different quantities of injection depending on the simulation case.
