Power System Reliability Assessment Algorithm

In this article, we provide a comprehensive explanation of how to implement power system reliability assessment algorithms using MATLAB. We demonstrate the implementation using the RTS79 system as a case study, which is a widely recognized practical power system benchmark. The article covers various aspects of the algorithm, including its fundamental principles, implementation steps, and interpretation/analysis of assessment results. We implement reliability indices calculation through probabilistic methods and system state enumeration techniques using MATLAB's matrix operations and statistical functions. The implementation includes key components such as load flow analysis, contingency screening, and reliability index computation using custom MATLAB functions and built-in toolboxes. We also discuss the algorithm's advantages and limitations, along with practical adjustments and improvements for real-world applications. Through this study, you will gain comprehensive understanding of power system reliability assessment algorithms and master their implementation and application using MATLAB programming environment.
