This paper focuses on the application of risk assessment in large power grid planning scheme using the state enumerate method. The risk evaluation models and methods for large power grid are presented. The contributions of critical component outages to the overall system risk are studied and utilized to find the weak area of a large power grid. This paper illustrates that the proposed methods and...
In today's electric power system, solid state power electronics technology plays more and more important roles and the demand for mega-watt level power ratings is increasing. The development of mega-watt power converters strongly depends on the state-of-the-art of power semiconductor technology, cooling technology and digital controller. The authors have been involved in the development of the emitter...
With the unbalanced distribution of regional resources and the imbalance in economic development and electricity consumption, a large amount of high quality and lower price electricity from small hydro-powers can only sell out through large power grid. And conflict between local and provincial power grid makes the lower price electricity from local small hydro-powers difficult to sell out, leading...
