Subsynchronous Resonance in DFIG‐Based Wind Farms: Mechanisms, Mitigation, and Future Directions—A Review

International Journal of Photoenergy, Volume 2026, Issue 1, 2026.
The increasing penetration of doubly fed induction generator (DFIG)–based wind farms, combined with series‐compensated transmission and weak grid conditions, has significantly heightened the risk of subsynchronous resonance (SSR). In modern power systems, SSR is manifested as subsynchronous control interaction (SSCI), due to adverse interactions ...

Stability Analysis of a Grid‐Connected DFIG Wind Farm Using Static VAR Compensator

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.
The integration of wind farms has greatly impacted the stability and performance of power systems. This is primarily due to the intermittent nature of wind energy, which requires advanced control strategies and robust grid‐integration techniques. This paper employs a Static VAR Compensator (SVC) equipped with a proportional integral (PI) controller to ...

Wide‐area damping control in renewable integrated power systems: A review on recent achievements and new challenges

Energy Conversion and Economics, Volume 6, Issue 6, Page 341-358, December 2025.
Abstract Low‐frequency oscillations (LFOs) remain a major obstacle to maintaining stable dynamic performance in power systems with high levels of renewable energy integration. In particular, inter‐area LFOs have emerged as a critical concern in large, interconnected grids.

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
