Hagkwen KIM1 and Chanan SINGH2 Texas A & M University, USA 1hagkwenkim@gmail.com, 2singh@ece.tamu.edu Abstract – As the components grow older, most power systems may enter a wear out stage indicating an aging trend. As a result, low reliability levels can cause higher operation costs and lower goodwill among customers and utilities. This paper is focused on aging effects in composite power system reliability evaluation. Quantitative reliability indices such as Loss of Load Expectation (LOLE), Loss of Load Frequency (LOLF), Expected Energy Not Supplied (EENS) are calculated and compared case by case. To sample the state of each component and to calculate desired indices, Sequential Monte Carlo simulation is introduced. The IEEE Reliability Test Systems is used to illustrate this technique. |
