Background:

• Power system stability is crucial for reliable electricity supply.
• Static Synchronous Series Compensators (SSSC) are used to improve transient stability.
• Tuning SSSC damping controllers effectively is challenging.

Purpose of the Study:

• To design and evaluate an Invasive Weed Optimization (IWO) based damping controller for SSSC.
• To enhance the stability of a Single Machine Infinite Bus (SMIB) system.
• To compare the performance of the IWO-based controller with a Particle Swarm Optimization (PSO) based controller.

Main Methods:

• A conventional PI controller was utilized as the SSSC damping controller.
• The Invasive Weed Optimization (IWO) technique was employed to tune the controller parameters.
• Controller parameters were optimized using a time integral of absolute error cost function.
• Time-domain simulations were conducted to assess system performance.

Main Results:

• The IWO-based SSSC damping controller demonstrated superior performance in enhancing SMIB system stability.
• The controller's effectiveness was validated under various loading conditions.
• Performance was also evaluated under different fault scenarios, showing robustness.
• IWO-based tuning outperformed PSO-based tuning.

Conclusions:

• The proposed IWO technique is an effective method for designing SSSC damping controllers.
• The developed controller significantly improves power system stability.
• The IWO approach offers a robust and efficient alternative for controller parameter tuning.
