To address the growing dynamic issues in power electronics-based system, this paper proposed an enhanced impedance-based stability analysis which can not only obtain global view of system dynamics, but also provide a tailor-made stabilization solution by direct use measured black-box models. With method, interactions at selected multiple ports are translated as decoupled single-input single-out...

The paper describes a method for investigating the impacts of wide-scale Plug-In Hybrid Electric Vehicle (PHEV) integration in electricity networks. It incorporates an agent-based transportation micro-simulation, which provides detailed temporal and spatial information of PHEV behavior including vehicle connection times, locations and energy demands. These inputs are subsequently used in power ...

One of the main problems in wind energy conversion system (WECS) is how to achieve maxim­u­m output power in different wind speeds. Maximum methods for maximum power point tracking in wind energy conversion syst­e­ms require the knowledge of system characteristics and mechanic sensors. So, using these methods practically will follow with high price and an abundant difficulties. In this pape...

This study based on investigation for integration wind power into conventional power system with its impact on fossil fuel generators and their generation management. Wind power as environmental friendly energy source can reduce the operational cost of the system due to considering no cost for energizing the generator in comparing with fossil fuel generators. However due to unpredictable nature...

Green computing, an emerging field of research that seeks to reduce excess power consumption in high performance computing (HPC), is gaining popularity among researchers. Research in this field often relies on simulation or only uses a small cluster, typically 8 or 16 nodes, because of the lack of hardware support. In contrast, System G at Virginia Tech is a 2592 processor supercomputer equippe...

Abstract – This paper proposes a PMU (Phasor Measurement Unit) based power oscillation detection system. The phasor angles at domestic 100V power outlets are collected to the server PC through internet, and the power oscillations and their various parameters are detected from the phasor angles. PMUs and servers are installed to Japanese 60Hz system, which is a large-scale longitudinal power sys...

Distribution systems can be operated in multiple configurations since they are possible combinations of radial and loop feeders. Each configuration leads to its own power losses and reliability level of supplying electric energy to customers. In order to obtain the optimal configuration of power networks, their reconfiguration is formulated as a complex optimization problem with different objec...
