Composite Power System Reliability Assessment Considering Transmission Line Flexibility
2020 International Conference on Probabilistic Methods Applied to Power Systems (PMAPS)（2020）
Abstract
Penetration of intermittent renewable generation, power market effects and dynamic conditions are driving the power system to an operation with higher flexibility. The concept of dynamic line rating is envisioned as a solution to enhance transmission system flexibility. This paper proposes to include the dynamic conductor thermal modeling on the composite power system reliability assessment using a sequential Monte Carlo simulation. An hourly capacity series for each transmission line is generated regarding the type of conductor, voltage level and weather conditions, respecting the maximum conductor temperature. The IEEE-RTS 79 is utilized to illustrate the proposed methodology.
