Optimal Placement of Static Var Compensator using Hybrid Optimization Technique

This paper discusses the effectiveness of hybrid optimization for the placement of Static Var Compensator (SVC) within electricity networks. The ultimate goal is to minimize transmission losses and enhance voltage stability by strategically positioning SVCs. The challenge of identifying the most suitable locations for SVC installation is addressed through a hybrid optimization framework. The practicality of the recommended framework is evaluated using the IEEE 14 and 30 Bus networks under various circumstances of loading. The evaluation involves comparing the performance of the traditional approach, which operates without (SVCs) with the results obtained from applying the hybrid optimization algorithm implemented in MATLAB R2020a. Results show that the hybrid approach demonstrated better system stability by achieving a voltage stability index that was around 2% lower than that of the traditional approach. Additionally, it showed improved energy efficiency by reducing real power losses by roughly 0.5%. Significantly more stable load voltages were ensured by the hybrid technique, which reduced load voltage variance by more than 50%. Its overall goal function decreased by about 0.1%, indicating improved system optimization. Furthermore, the hybrid approach was a more economical alternative because its hourly operating costs were about 0.03% lower. SVCs enhance voltage stability, reducing grid unpredictability and facilitating the integration of renewable energy sources. They contribute to climate objectives, support sustainable transitions, and manage complex, high-capacity networks while ensuring their reliability and resilience.
