Abstract
Electrical grid across the world are now adapting towards environmentally friendly operation with various renewable sources being introduced. Among them, the reputation of electrical generation by wind has benefited the most ground. Wind, as one of the meteorological conditions, also has high impact on line ratings and such manner of operating the line is known as dynamic thermal rating (DTR) system. Demand side management (DSM) and Dynamic Thermal Rating systems (DTR) play a vital role in mitigating some of the challenges faced by electric power services. Seeing this contact, it is intuitively important to investigate the reliability of an electrical network incorporating DTR, DSM and wind farm. Hence, the objective is to propose a methodology that can perform this task. In the methodology, sequential Monte Carlo (SMC) simulation was performed due to time dependencies of line ratings and wind power. As a result, modeling of these time-series data was performed using the auto-regressive and moving-average (ARMA) model. Moreover, correlations between line rating and wind power were also considered to provide a practical approach to the modeling. Results have demonstrated that DTR system can expand arrange reliability and takes into consideration higher breeze vitality entrance.
