Nowadays, water pollution is one of the most important issues on which much attention has been paid. As an effective water treatment method, activated sludge process has been widely used for water purification. However, excess sludge that results from the water treatment still brings pollution to environment. Anaerobic digestion has been used in a broad range of applications in excess sludge stabilization...
With the increasing problems of emission from oil/gas powered vehicles and the decreasing of fossil fuel around the world, the electric vehicles (EV) and hybrid electric vehicles (HEV) have gained wide attention. Among them, the internal combustion (IC) engine and the electric machine based HEV become the most promising alternatives for the next generation vehicles [1]. The HEV provides the advantages...
This paper presents the modeling and simulation work completed in the project sponsored by ONR grant N00014-08-C-0227. The project is to investigate new design concepts of all-electric ship integrated power systems (IPS) and to develop PEBB-based converter models that will represent the existing commercially available products with adequate details and interfaces to allow them to be used in various...
Reactive power plays a crucial role in power system operation and voltage management. However reactive power issues have rarely been considered in reliability evaluation of power systems. This paper investigates the effect of reactive power on reliability of the 220 kV Taiyuan Power System in Shanxi Province of China. Reactive power shortage and the associated voltage violations due to the failures...
