This was done in response to on-going criticism from the scientific community. The name of those devices was also changed from lightning eliminators/dissipation arrays (DAS) to charge transfer systems (CTS). This paper summarizes and rebuts both past and present theories that have been proposed by the manufacturers. It also discusses manufacturers' claim of success and explains why eliminating lightning is still considered to be not feasible. Finally, comments are given regarding the attempts of the manufacturers to get a standard for their devices.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.

In this paper, main features of the new PJM market design are described. The LP-based framework for the advanced FTR auction market-clearing problem is presented and the marginal market clearing prices (MCP) for option FTRs are defined. Properties of the advanced FTR market are demonstrated using a 5-bus exemplar network and the realistic PJM market model.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.

With these criteria, new capacity is determined when the system load is just equal to the system limited time rating. Even, some electrical utilities in North America allow for some positive reserve margin in order to cover for load forecast uncertainty. These deterministic criteria do not quantify the reliability of the system and in many situations, can result in over-designed systems and therefore, the electricity users can end up paying higher prices for electricity. In a competitive electricity market, transmission system owners or providers should try to keep the cost of upgrading, operating and maintaining their systems as low as possible while meeting the expectations of their customers and regulatory rules. This paper describes the application of a value-based approach to the planning of customer delivery systems. In this application, the reliability of the system is expressed as a function of the reserve margin and the optimal reserve level is obtained when the total system cost is minimal. Sensitivity studies are carried out to determine the impact of changes in some key parameters on the optimal reserve margin. An example is presented to illustrate the concepts involved.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.

As a consequence new definitions for electrical quantities under nonsinusoidal conditions have been discussed particularly in view to apply a fairer distribution of the financial burden required to operate the electrical system and to maintain the quality of the service. It is important to know what impact the introduction of any new definition will have on the overall rate structures and billing charges, particularly those applied to the major industrial clients. This paper investigates the performance of revenue meters which are based on existing definitions in comparison with some of the measuring methods proposed in the new IEEE Standard 1459-2000, for test waveforms of field recorded data.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.

To determine an appropriate level of security, one should perform a probabilistic cost/benefit analysis that balances the cost of the security margin against its benefits, i.e. the expected societal cost of the avoided outages. This paper shows how a previously published method based on Monte Carlo simulation can be enhanced to take into account time-dependent phenomena such a cascade tripping of elements due to overloads, malfunction of the protection system and potential power system instabilities. In addition, the importance of using failure rates that reflect the weather conditions is discussed. Studies based on the south-western part of the transmission network of England and Wales demonstrate the validity of the models that have been developed.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.

This paper compares the LR and the state of art general MIP method for solving UC problems based on performance analysis and numerical testing. In this paper we have rigorously proved that UC is indeed an NP complete problem, and therefore it is impossible to develop an algorithm with polynomial computation time to solve it. In comparison with the general MIP methods, the LR methodology is more scaleable and efficient to obtain near optimal schedules for large scale and hard UC problems at the cost of a small percentage of deviation from the optimal solution. In particular, solving hydro generation subproblems within the LR framework can take advantages of both LR and general MIP methods and provide a synergetic combination of both approaches.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.

This paper presents a DSP-based hardware monitoring system based on a recently proposed PQ classification algorithm. The algorithm is implemented with a Texas Instruments (TI) TMS320VC5416 digital signal processor (DSP) with the TI THS1206 12-bit 6 MSPS analog to digital converter. A TI TMS320VC5416 DSP starter kit (DSK) is used as the host board with the THS1206 mounted on a daughter card. The implemented PQ classification algorithm is composed of two processes: feature extraction and classification. The feature extraction projects a PQ signal onto a time-frequency representation (TFR), which is designed for maximizing the separability between classes. The classifiers include a Heaviside-function linear classifier and neural networks with feedforward structures. The algorithm is optimized according to the architecture of the DSP to meet the hard realtime constraints of classifying a 5-cycle segment of the 60 Hz sinusoidal voltage/current signals in power systems. The classification output can be transmitted serially to an operator interface or control mechanism for logging and issue resolution.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.
