Theoretical Analysis of Active–Reactive Power Decoupling Control for DSSC Based on Magnetically Coupled Reactors

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
Distributed Static Synchronous Compensator (DSSC) is essential for flexible power flow control in renewable energy integrated systems but suffers from severe active–reactive power coupling that deteriorates voltage quality and dynamic performance. This paper proposes a hardware‐assisted decoupling method using magnetically coupled reactors (MCRs) to ...

OPF With SVC and UPFC Modeling for Longitudinal Systems

IEEE Transactions on Power Systems, 2004
This paper presents a formulation of the Optimal Power Flow problem with an explicit modeling of Static Var Compensator (SVC) and Unified Power Flow Controller (UPFC) devices. The optimization problem is solved by using Sequential Quadratic Programming, where two convergence criteria and four different methods are studied to solve the quadratic ...

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 ...

A Fast-Response Power-Flow Control Strategy of MMC-UPFC Based on Active Disturbance Rejection Control

IEEE Access
The unified power flow controller (UPFC) based on the modular multilevel converter (MMC) requires stability and fast power-flow-regulation capabilities, whereas the linear active disturbance rejection control (LADRC) strategy precisely has the ...

Transformerless UPFC Using Multilevel Inverter

International Journal Of Engineering And Computer Science, 2017
This paper proposes transformer-less Unified Power Flow Controller (UPFC) which can be able to control the parameters of the transmission line. It incorporates back to back inverter that requires large transformers for power flow injection. The transformers are somewhat bulky, very costly and introduce high losses due to magnetic properties of the ...

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.
