Congestion in the transmission lines is one of the technical problems that appear particularly in the deregulated environment. The voltage stability issue gets more important because of heavy loading in this environment. The main factor causing instability is the inability of the power system to meet the demand for reactive power. This paper presents a new approach for alleviation congestion re...

This paper presents a mixed integer programming based approach for optimal placement of DC model of Unified Power Flow Controller in the deregulated electricity environment. The method accounts for DC load flow equations taking constraints on generation, line flow, and UPFC parameters. The security of transactions has become important issue to reserve the available transfer capability. Therefor...

We conduct an experimental analysis to identify the most computational time consuming fragments of software and hardware that will likely be an integral part of power exchanges in a deregulated environment. The empirical analysis provides insights into the scalability of the system as a function of branch congestions, excess/scarcity of power, average size of multi-lateral contracts, topology a...

This paper presents design of wavelet based multi resolution controller to deal with load frequency control problem of multi area power system under deregulated environment. This proposed novel control strategy shall take care of nonlinearities in an effective manner. This proposed controller is tested on open access two area power system under one possible contract scenario. The performance of...

Based on evidence for 61 countries in 1980-97, this study finds that explicit deposit insurance tends to increase the likelihood of banking crises, the more so where bank interest rates are deregulated and the institutional environment is weak. Also, the adverse impact of deposit insurance on bank stability tends to be stronger the more extensive is the coverage offered to depositors, where the...

Deregulation of the Hedgehog (Hh) signaling pathway is associated with the development of human cancer including medullobastoma and basal cell carcinoma. Loss of Patched or activation of Smoothened in mouse models increases the occurrence of tumors. Likewise, in a Drosophila eye model, deregulated Hedgehog signaling causes overgrowth of eye and head tissues. Surprisingly, we show that cells wit...

Given the autonomous nature of various decisionmaking entities in deregulated power systems, this paper embraces a paradigm based on software agents and multiagent systems for distributed rational decision-making in electric power systems. Our current effort in this line of research is aimed at producing a platform-independent, robust application program interface for instantiating complex mult...

This paper discusses the temporal fit of teams of controllers to a real world hydropower system (HPS) in a deregulated market environment, emphasizing how well displays support quality of control performance by industry controllers. The results of an empirical evaluation suggest that displays that integrate task constraints over appropriate time scales help controllers construct more immediate ...

Electric power restructuring offers a major change to the vertically integrated monopoly. The change manifests the main part of engineers’ efforts to reshape the three components of today’s vertically integrated monopoly: generation, distribution and transmission. In a restructured environment, the main tasks of these three components will remain the same as before, however, to comply with ...
