As the process of deregulation of the electric utility industry proceeds, the importance of power quality is increasing. A fundamental aspect of power quality is the continuity of power supply that is the absence of momentary, temporary and sustained power interruptions. In this paper a network reconfiguration strategy is proposed which allows the distribution network to separate into a certain...

In deregulated power systems, competition could push the system near its security limit. The issue of power system stability is becoming more crucial. The excitation and governing controls of generator play an important role in improving the dynamic and transient stability of power system. Typically the excitation control and governing control are designed independently. In this paper, we prese...

Traditionally, the impacts of the rights of fi nancial institutions and workers on corporate performance have been analyzed independently. Yet, theory clearly indicates that the combination of relative powers of different stakeholders affects a fi rm overall performance. Using U.S. state level and state-industry level data, we investigate how output growth is affected by bank branch deregulatio...

Are we ready for more perfect storms? W ith the tragic events of 9/11 permanently etched in our minds, the massive 14 August power outage evoked eerie reminders of what shook our world 2 years ago. While preliminary reports indicate that there was no apparent evidence of terrorism, the cascading blackouts were a sudden illumination of our electricity infrastructure's vulnerable condition. This ...

Currently, the electric industry is undergoing a complete transformation and restructuring due to the concurrent convergence of deregulation and the advent of Distributed Generation (DG). Some years ago, electricity was produced in some big power plants and a few vertically integrated electric utilities covered all the steps in the electricity supply: generation, transmission, distribution and ...

Research attention has been powered to understand the functional roles of non-coding RNAs (ncRNAs). Many studies have demonstrated their deregulation in cancer and other human disorders. ncRNAs are also present in extracellular human body fluids such as serum and plasma, giving them a great potential as non-invasive biomarkers. However, non-coding RNAs have been relatively recently discovered a...

This article proposes a new method to increase a power system's security margin and/or support its low voltage buses by re-dispatching generator outputs, using a normal vector found at a voltage collapse boundary or a low voltage boundary (LVB). This method uses the normal vector as an indicator to change the generation direction so that more power can be transferred before reaching a boundary ...

In the deregulated environment of power systems, the transmission networks are often operated close to their maximum capacity to achieve transfer of power. Besides, the operators must operate the system to satisfy its dynamic stability constraints under credible contingencies. This paper provides a method using trajectory sensitivity to reschedule power generation to ensure system stability for...
