In order to resolve the issue of the power supply-and-demand balance that has been triggered by the increased use of renewable energies, the traditional supply-and-demand adjustment on the power supply side is already regarded as inadequate. The potential for a new supply-and-demand balancing mechanism considering the demand side is currently under active deliberation. The “demand response” (DR...

One of the fundamental tenets in deregulation of the power system is to provide fair and open access to transmission facilities. This requires that market participants, both power brokers and generation companies, have complete and timely information as to the transmission availability. The present system of posting available transmission capacities (ATC) is useful but limited because there is ...

Due to the deregulation in the electrical market, difficulties in building new transmission lines, and the continuous increase in power demand the maintenance of power system stability becomes difficult and a very challenging problem. In large, interconnected power system damping is often reduced, leading to lightly damped electromechanical modes of low frequency oscillations (0.1~0.6Hz). In th...

this paper introduces an indirect adaptive fuzzy sliding mode controller as a power system stabilizer for damping local and inter-area modes of oscillations of multi-machine power systems. this controller is designed based on the combination of sliding mode controller and the fuzzy logic systems. the fuzzy systems are used to approximate the unknown functions of power system model. generator sp...

Power had not yet been fully restored following the recent blackout that some were already clamoring that increasing transmission capacity is the best way to avoid a repetition of these events. Others were laying the blame squarely on the deregulation of the electricity supply industry. Should the United States embark on a massive investment program? Should deregulation be abandoned on the grou...

This paper addresses the data ownership and information exchange issues as they relate to operating the power system in the new, restructured environment. The power system liberalization, privatization and deregulation have introduced a new view regarding data ownership. This may now be different from the situation seen in the past where all the entities of the power system (generation, transmi...

In this paper, a brief review on some of the interesting open research issues in the area of deregulated electricity market is made. To mention them, Power electronics application in power systems, machine design and location of distributed generation in the distribution systems are some.

Deregulation and privatization are posing new challenges to high voltage transmission and distributions systems. System components are loaded up to their thermal limits, and power trading with fast varying load patterns is leading to an increasing congestion. In addition to this, the dramatic global climate developments call for changes in the way electricity is supplied [1, 2]. Innovative solu...

The paper discusses roles, issues and possible conflicts concerning the electricity trading infrastructure of a small hydro-system, such as that of Iceland. Some critical elements of successfully implementing the infrastructure are discussed. In particular, the metering and settlement (M&S) systems are discussed and the arguments for an single independent M&S entity are provided. Furthermore, t...

In this present era , a fair transmission pricing scheme is an important issue due to incresed deregulation and restructuring of power sector. In this view, issue of tracing the flow of electricity has been gain importance as its solution helps in evaluating a fair and transparent tariff.An electricity tracing method would make it possible to charge the generators and/or consumers on the basis ...
