A Systematic Literature Review on Auction Mechanisms: Insights From the Last Decade and Future Directions

Journal of Economic Surveys, Volume 39, Issue 5, Page 1971-1998, December 2025.
ABSTRACT This study reports the results of a systematic literature review on auctions mechanism. Auctions are a very popular practice employed in many fields but does not exist a research that investigates the use of auctions under a cross‐disciplinary approach. This work is focused on analyzing which are the areas where auctions are mostly adopted and

Optimal Location and Sizing of Static Var Compensator (SVC) to Improve Voltage Profile in Distribution Network

Engineering Reports, Volume 7, Issue 10, October 2025.
Optimized placement of SVC in a 33‐bus distribution system improves voltage profile, increasing the voltage profile from 94.69% to 97.90%, ensuring voltages remain within acceptable limits (0.95–1.05 p.u.) using optimal capacitor sizing and location, enhancing system reliability and power quality.
