Structure and Hierarchical Control Method of Battery‐Based Hybrid Power Flow Controller

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
This article proposes a battery‐based hybrid power flow controller (B‐HPFC), offering enhanced flexibility for power flow regulation and energy storage. First, the structure of B‐HPFC is given, where the cascaded H‐Bridge (CHB) is integrated with the phase‐shifting transformer (PST). The batteries are connected to the modules of CHB.

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 ...
