Tóm tắt

Reliability of Power System research has a long history. The topic includes three levels: the first relates to
generation facilities, the second refers to the integration of generation and transmission, the third one refers to the
complete system including distribution system. The first level is a basic step for the next level, still being interested,
especially on researches on the renewable energy sources integration. Monte-Carlo simulation is used to describe the
power state of traditional generations, wind turbines and the hourly load of the power system. In particular, the
2055MW wind turbine is simulated in four states. The reliability test power system IEEE-RTS version 1979 was used to
verify the simulation method. Four scenarios of the share of wind power were tested: 0.2%, 2.4%, 3.6%, 4.8%. Each
scenario was simulated respectively with different load levels. The results show that the reliability is slightly changed
when the share of wind power is negligible (0.2%). However, the reliability changes dramatically only with 2.4% of the
share of wind power. The greater the wind power integration, the lower the reliability when considering the results of
the other scenarios. This paper also shows a significant increase in the loss of load expectancy (LOLE) as the annual peak
load increases of 100MW.
