Abstract: With the development of power grid construction and the constantly emerging of new power generation and transmission techniques, the new requirements for power system reliability evaluation are put forward in the aspects of accuracy and comprehensiveness. Starting with the reliability modeling of generation and transmission components, the trends of multi-state models with more consideration factors of the generation and transmission components were analyzed. The probabilistic reliability modeling methods for ultra HVDC transmission, VSC-HVDC, wind power plants with energy store devices, FACTS devices and electric vehicles were discussed, as well as their effects on generation and transmission system reliability and the existing shortcomings of the new devices. Finally, the problems to be further researched in future were proposed.

Key words: power generation and transmission system, reliability, component, model, new technology
