Secure Switch-and-Stay Combining (SSSC) for Cognitive Relay Networks [PDF]

IEEE Transactions on Communications, 2016
In this paper, we study a two-phase underlay cognitive relay network, where there exists an eavesdropper who can overhear the message. The secure data transmission from the secondary source to secondary destination is assisted by two decode-and-forward (DF) relays.

Nature‐Inspired Janus Actuators with Structurally Engineered PEDOT:PSS

Small, Volume 22, Issue 2, 8 January 2026.
Nature‐inspired PEDOT:PSS Janus actuators are fabricated through a dual solvent‐acid treatment that induces asymmetric conductivity and hydrophobicity within a unified structure. The actuator demonstrates large, reversible bending (3 cm−1) under low voltage (4 V), heat, and vapor stimuli, with minimal Joule heating and excellent cyclic durability ...

Value‐Based Reinforcement Learning for Inter‐Area Oscillations Mitigation in PV‐Integrated Power Systems

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
Enhanced critic‐only DQN with smoothing enables continuous SVC control for damping inter‐area oscillations. The state selection via participation and residue analysis captures critical key modes. Orthogonal array efficiently tunes hyperparameters with low cost.

Model Predictive Control of a Parallel Transformerless Static Synchronous Series Compensator for Power Flow Control and Circulating Current Mitigation

Energies
The paper proposes a parallel transformerless (TL) static synchronous series compensator (SSSC) for the control of power flow along the power distribution lines under balanced or unbalanced voltages. This new SSSC configuration offers the advantages of a

A Two‐Stage Transient Current Differential Protection Method Considering Fault Inception Angle

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
To address the performance degradation of conventional protection in renewable‐rich power systems, this paper proposes a novel two‐stage transient current differential protection method that accounts for the fault inception angle. As illustrated in the graphical flowchart, the scheme adaptively adjusts the analysis time‐window based on real‐time ...

THE COMPARATIVE STUDY OF STATCOM WITH FC-TCR AND SSSC

International Journal of Engineering Technologies and Management Research, 2020
The Flexible Alternating Current Transmission Systems (FACTS) device deals with the control of power flow, alternating current of transmission line and immediately respond towards the stability problems of the system. The present paper show that how the FACTS devices enhance the different parameter of the power systems like power transfer capacity of ...

Direct Method for Transient Stability Assessment of a Power System with a SSSC

Journal of Computers, 2007
This paper proposes the energy function of a power system with a Static Synchronous Series Compensator (SSSC). They make it possible for the direct method to acquire the transient stability or critical clearing time assessment of a power system. The proposed energy function of a power system with a SSSC is first derived and then it is used for SSSC ...

A Large‐Disturbance Dynamic Stability Constrained Optimal Power Flow Methodology Based on Trajectory‐Eigenvalue Sensitivity

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel large‐disturbance dynamic stability constrained OPF model (LDDSC‐OPF) that simultaneously optimizes both damping torque and synchronous torque under large disturbances. A TE sensitivity‐based method is developed to solve the LDDSC‐OPF model.
