Reasonable maintenance strategy can decrease power grid operation costs and enhance competitiveness of power grid. Therefore, according to the principle of system condition-based maintenance, an equipment imperfect maintenance model is built based on a modified Kijima II model, which considers electrical equipments' maintenance outage model and repair outage model and the effects of equipment maintenance...
Cloud computing provides a new paradigm for easy access to larger scale computing resources over the Internet, thus offering an alternative solution to huge data processing and heavy computational work in power system. In this paper, InterPSS Cloud Edition, a cloud computing based platform for power system analysis, is set up by InterPSS development team using Google App Engine (GAE). At the current...
Cascading failures present severe threats to power grid security, and thus vulnerability assessment of power grids is of significant importance. Focusing on analytic methods, this paper reviews the state of the art of vulnerability assessment methods in the context of cascading failures. These methods are based on steady-state power grid modeling or high-level probabilistic modeling. The impact of...
Large blackouts are typically caused by cascading failure propagating through a power system by means of a variety of processes. Because of the wide range of time scales, multiple interacting processes, and the huge number of possible interactions, the simulation and analysis of cascading blackouts is extremely complicated. This paper defines cascading failure for blackouts and gives an initial review...
