Growing grid complexity and loading are increasing the risk of cascading failures and large-scale blackouts. Traditional reliability enhancement technologies offer only incremental improvements. Emerging technologies are limited by their complexity, and need for extensive real time analyses. A better solution is to segment the grid into AC sectors interconnected by HVDC links. In a segmented system...
This paper reviews, from an application perspective, a method for operating parallel bipole and monopole system in such a way as to use all three conductors of a converted three phase ac line while eliminating the need for ground return current. The characteristics of the resulting "tripole" HVDC scheme are discussed as they relate to system operating needs, including increases in line rating,...
The role of information technology (IT) in education has significantly increased, but resistance to technology by public school teachers worldwide remains high. This study examined public school teachers' technology acceptance decision-making by using a research model that is based on key findings from relevant prior research and important characteristics of the targeted user acceptance phenomenon...
