| dc.description.abstract | This project presents a probabilistic study and evaluation of a power systems network with
variable parameters. The study aimed to analyze the behavior of the network under uncertain
conditions and assess the impact on bus voltages.
Initially, a deterministic load flow analysis was performed to establish a baseline understanding
of the power system. Emphasis was placed on monitoring the voltages at each bus, their
deviations from the rated voltage and the results were carefully recorded for further analysis.
Subsequently, distribution functions were modeled for various network parameters, including
line resistance, loading, and generation. Goodness of fit tests were conducted to ensure the
suitability of the chosen distributions.
To incorporate uncertainty into the analysis, a Monte Carlo simulation was employed to perform
probabilistic load flow calculations together. The focus remained on evaluating the voltage
results throughout the system. The probabilistic load flow analysis yielded valuable insights
into the power system’s behavior. Key results included the identification of minimum and
maximum voltage values at each bus, the probability of voltage limit violations, as well as the
expected duration and frequency of voltage violations.
Using this information, an assessment was made to determine the load level at which the
bus voltages exceeded acceptable ranges. These findings provide crucial guidance for system
operators and planners to prevent potential voltage violations and optimize the performance of
the power network. Based on the study’s results and conclusions, several recommendations are
proposed to improve the power system’s resilience and ensure stable voltage conditions. These
may include implementing corrective measures, such as adjusting the network parameters or
introducing additional voltage control devices. | en_US |
