This paper presents novel corrective control actions to alleviate overloads in transmission lines by the Particle Swarm Optimization (PSO) method. Generator rescheduling and/or load shedding is performed locally, to restore the system from abnormal to normal operating state. The appropriate identification of generators and load buses to perform the corrective control action is an important task...

The construction of a cyber physical system in a power grid provides more potential control strategies for the power grid. With the rapid employment of intelligent terminal equipment (e.g., smart meters and intelligent appliances) in the environment of a smart grid, abundant dynamic response information could be introduced to support a secure and stable power system. Combining demand response t...

Due to the limited generation, finite inertia, and distributed structure, microgrid suffers from large frequency and voltage deviation which can lead to system collapse. Thus, reliable load shedding method to keep frequency stable is required. Wireless network, benefiting from high flexibility and low deployment cost, is considered as the promising technology for microgrid management. In this p...

As the requirements of economical operation and reliability on power grid are enhanced gradually nowadays, the existing under frequency load shedding (UFLS) scheme is not quite fit for the modern power system that integrates high wind power. In this paper, the impacts of high wind power penetration on the UFLS are discussed thoroughly. A novel adaptive load shedding (LS) scheme is presented tak...

In recent years, voltage limit violation and power system load-generation imbalance, i.e., line loading limit violation have been responsible for several incidents of major network collapses leading to partial or even complete blackouts. Alleviation of line overloads is the suitable corrective action in this regard. The control action strategies to limit the line loading to the security limits ...

A voltage collapse event is complex and localized in nature, but its effect is extensive. A vital effect of voltage collapse is total system collapse or blackouts, which will result in a significant loss to utility companies. Online monitoring of power system stability has thus become an important factor for electric power utilities. The final resort prevent the occurrence of a voltage collapse...

This paper presents an overview of the architecture for smart Nano grids, Integration of various diversified distributed generation technologies in Nano grids at small community level and different policies governing its implementation. The paper also reviews the current energy scenario of Pakistan with emphasis on the need of setting up small scale Nano grids with integration of V2G technology...

As most data stream sources exhibit bursty data rates, data stream management systems must recurrently cope with load spikes that exceed the average workload to a considerable degree. To guarantee low-latency processing results, load has to be shed from the stream, when data rates overstress system resources. There exist numerous load shedding strategies to delete excess data. However, the cons...

A single rotavirus strain causing asymptomatic infections as well as severe gastrointestinal disease has been described in the neonatal nurseries of the Christian Medical College, Vellore. In this study, quantitative real-time RT-PCR was used to determine the association of viral load with the presence of gastrointestinal symptoms in neonates. Viral load was estimated in terms of the crossing p...

In the field of power systems there is an active research on methods to limit the peak load of power demand. Recently, a new approach to the automatic management of electric loads has been proposed, which is based on scheduling techniques derived from real-time computing systems. The research on real-time scheduling encompasses several aspects, including scheduling algorithms and analysis techn...
