How far can one compress digital fault records? Analysis of a matching pursuit-based algorithm
Michel P. Tcheou,André L. L. Miranda,Lisandro Lovisolo,Eduardo A. B. da Silva,Marco A. M. Rodrigues,Paulo S. R. Diniz +5 more
TL;DR: It is verified how far electric disturbance signals can be compressed without compromising the analysis of encoded fault records, and the DSMP is a reliable compression system since it achieves high compression ratios (6.4:1) without causing fault analysis misinterpretation.

Long term voltage stability thevenin index using voltage locus method
TL;DR: In this paper, the voltage locus of the load phasor as a function of load increase is studied from a geometric perspective, and a voltage stability index based on the magnitude of the measured voltage and calculated thevenin equivalent angles is presented.

Centralized volatility reduction for electricity markets
TL;DR: In this paper, the authors propose an insurance market that complements any wholesale market design to reduce the financial impacts of volatile electricity market prices by providing theoretical guarantees, analytically characterize the outcomes over a copperplate power system example, and numerically explore the same for a modified IEEE 14-bus test system.

Distributed generation based on renewable energy providing frequency response ancillary services
Fahad Alsokhiry,K. L. Lo +1 more
TL;DR: In this article, the feasibility of DGs based on wind and solar energies to provide ancillary services to medium-scale micro-grid was investigated, where a generic model of IEEE distributed generation system with 13 buses was used as a test network.
