TL;DR: In this article, a carbon-coated LiFeP0 4 Li-ion cathode material was studied for its electrochemical and thermal performance, which showed that the carbon coating improves the electronic conductivity and hence the cycling of this material.
Abstract: The carbon-coated LiFeP0 4 Li-ion cathode material was studied for its electrochemical and thermal performance. This electrode exhibited a reversible capacity corresponding to more than 90% of the theoretical capacity when cycled between 2.5 and 4.0 V. The material also showed good capacity retention at high powers, implying that the carbon coating improves the electronic conductivity and hence the cycling of this material. The diffusion coefficient of this material was calculated from its electrochemical impedance spectroscopy. The heat generation during charge and discharge was studied using an isothermal microcalorimeter. Thermal studies were also investigated by using a differential scanning calorimeter and an accelerating rate calorimeter, which showed that LiFePO 4 is safer than the commonly used lithium metal oxide cathodes with layered structures.

16 Oct 2006TL;DR: In this article, a wide-area measurement-based secondary voltage control of the extensive park of dynamic shunt compensators in our grid using a single pilot voltage from the load center is presented.
Abstract: This paper recalls the 30-year history of wide-area measurements at Hydro-Quebec. At present, a state-of-the art, eight-PMU-based wide-area monitoring system commissioned in 2004 is on line, feeding the EMS with GPS-synchronized angles, frequencies, and harmonic distortion measurements from key 735-kV buses. Specific to Hydro-Quebec is the current use of one such system for frequency regulation reporting and control-room implementation of preventive measures against geomagnetic storm-induced contingencies. Building on this experience, the Hydro-Quebec research institute, together with TransEnergie, is developing advanced applications which, in the long term, will go beyond active monitoring to safely initiate targeted control actions aimed at extending system power transfer limits with respect to both transient and long-term stability. In addition to the major improvement in inter-area mode damping shown previously by the authors, this paper demonstrates that, surprisingly, wide-area control of static VAr compensators (SVC) will also vastly extend the first-swing stability margins. Finally, initial results on a wide-area measurement-based secondary voltage control of the extensive park of dynamic shunt compensators in our grid using a single pilot voltage from the load center are very encouraging.

01 Apr 1996TL;DR: In this paper, the authors proposed an approach to quantifying the distortion caused by a single customer, when there are many customers in the network, by isolating the contributions to waveform distortion from a customer side and the supply side.
Abstract: In this paper, we propose an approach to quantifying the distortion caused by a single customer, when there are many customers in the network. We have described a method for isolating the contributions to waveform distortion from a customer side and the supply side. The voltage and current measurements at a single point are sufficient. This approach will be useful in arriving at equitable ways of settling customer complaints, sharing the cost of waveform distortion through rate structures, penalties, etc. The principle is illustrated using six example loads. The method proposed can be implemented in any power quality measurement device, which monitors the voltage as well as the current harmonics simultaneously.
