development, with renewable and non-renewable
sources being the most environmentally friendly. One
advantage of a hydropower plant is that it produces
clean, renewable energy, while a disadvantage is that it
can have negative impacts on local ecosystems and
wildlife. This study focusses on monitoring and
assessing faults such as changes in reference power and
three-phase short circuits in hydropower plant. The
analysis involves examining these faults in various
parameters, including voltage and current of the
generator, power and reactive power, generator output
power, deviation in generator speed from its rated
speed, generator rotational speed, torque, and d and q
axis voltage of the generator. The simulations were
conducted using MATLAB/Simulink. The results of the
simulations demonstrate the effects of these faults on
the parameters, providing valuable insights for
monitoring the hydropower plant under such
conditions. Overall, the generator's performance in
both scenarios demonstrates its reliability and
effectiveness in maintaining power supply during
unexpected events. The successful outcomes in both
cases highlight the importance of having a robust and
well-functioning generator system in place for ensuring
continuous power supply.
expected to have a crucial and significant function in the electricity market. Small-scale generators are electric power
generation sources that are used scattered in the grid to provide the electricity consumers need and are directly
connected to the grid or the consumer's place. This is primarily driven by the move away from traditional power
generation sources and regarding RES and EVs. Throughout the globe, utilities, sustainability, and communities all
benefit greatly from this transition. Nevertheless, using EVs will have positive and negative effects on the distribution
grid. There are many challenges for EVs and the grid when they are connected to the grid. It is essential to assess and
analyze the integration of vehicles into the grid that incorporates detailed mechanical and electrical components of EVs
and power systems. We examine two important analyses in the power system including RES and PHEV namely, load
flow and short circuit calculation. Moreover, this paper defines three cases in load flow analysis and short circuit
analysis for 63, 20 KV and explains economic analysis up to the cases, while using DIgSILENT, the analysis is carried
out. In conclusion, the findings of this study highlight the signific
