Abstract
The complexity and complexities of the current electric power system, which has integrated various generating sources as well as huge transmission and
distribution networks, are the focus of this research. The basic purpose of the power system is to meet load demand economically while maintaining continuity and quality. However, random equipment failures often lead to service interruptions for customers, affecting the reliability of power supply. Therefore, power engineers must prioritise reliability while designing and planning the power system network. Thus, Dynamic Thermal Rating (DTR) system need to be investigated more on a power system and for this project, it will be 24-bus system. DTR takes into account real time weather conditions, dynamic loading patterns, and conductor temperature variations to provide more accurate transmission line ratings. The goal is to increase system reliability and efficiency by minimizing the likelihood of insufficient supply to meet demand which is the Loss of Energy Expectation (LOEE) and optimizing load management strategies. The focus of this project will be on evaluating the reliability impact of integrating a Dynamic Thermal Rating (DTR) system using the RTN through Sequential Monte Carlo (SMC) simulation. As a result, there are improvement in system reliability, as evidenced by the lower LOEE in DTR than static. The implementation of DTR system demonstrates the effectiveness in mitigating the risk of power supply shortages.
