    The present research proposal consisted of the analysis of the dynamic behavior of an electrical power system considering the introduction of renewable energies, within the project it was possible to verify the lack of detailed understanding of how it affects the stability and transient response of the SEP, for which a sizing of a photovoltaic system point to a 3-bus Power Electrical System has been carried out. In the analysis carried out, it was found that the integration of renewable energies and the implementation of technologies such as MPPT (Maximum Power Point Tracking) and PLL (Phase-Locked Loop) have a positive impact on the power system, albeit in a subtle manner. The results showed a slight improvement in the voltage values of buses B2 and B3 when using these technologies. This improvement, although small, suggests that MPPT and PLL help increase system stability and efficiency by optimizing voltage regulation. Causing the sinusoidal signals in the system to no longer be perfectly sinusoidal, presenting slight differences that, although almost imperceptible, reflect the effect of these new technologies. On the other hand, Bar B1 maintains a constant voltage in all cases and at all times, indicating that it is not affected by the variations introduced by renewable energies or by the use of MPPT and PLL. The reference bar, or slack bar, ensures a stable voltage in the system, which contributes to the overall stability. The moderate fluctuations in busbar voltages connected to the PV system highlight the importance of MPPT and PLL in managing these variations and maintaining grid stability, although MPPT and PLL technologies offer subtle improvements in stability and efficiency.
