Small signal stability constrained optimal power flow model based on trajectory optimization

Energy Reports, 2023
The essence of traditional power system’s small signal stability analysis model using the eigenvalue analysis method is to analyze the time-invariant system obtained after the approximate linearization of the system, because it only considers the ...

Intelligent Impedance‐Based SSR Mitigation in Photovoltaic Systems via Genetic Algorithm Optimization

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel impedance‐based approach for mitigating sub‐synchronous resonance (SSR) in grid‐connected photovoltaic systems. A supplementary virtual impedance controller, optimized using a genetic algorithm, is designed to adaptively damp SSR under varying operating conditions, with performance validated through eigenvalue, impedance ...

SSR mitigation with SSSC thanks to fuzzy control

TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2013
This paper deals with the capability of a static synchronous series compensator (SSSC) to attenuate the subsynchronous resonance (SSR). Two well-known controllers are designed, namely a conventional damping controller (CDC) and fuzzy logic damping controller (FLDC).

Optimal Placement and Sizing of Series and Shunt Compensation for Improving Power Systems Operation

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Power systems are complex, and power demand has constantly increased over time. Moreover, power transmission systems have a limited capacity, causing the increase in demand to be difficult to accommodate. Additional system requirements include maintaining voltages within specific values and limiting voltage drop in the lines to ensure voltage stability,

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 ...

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 ...
