A Hybrid Stability Index and Harris Hawks Optimization for the Optimal Reallocation of Generators in the Presence of SVC

Increasing system efficiency and dependability in a very competitive power market depends on best use of available resources. This work offers a hybrid approach for generator tuning and Static VAR Compensator (SVC) placement selection to enhance system performance. The perfect generator settings are found using the Harris Hawks optimization (HHO) method; a hybrid stability index (HSI) is then used to choose the best SVC location. Measuring voltage stability, the HSI combines the Vi/Vo index with the L-index. A multi-objective function is developed to lower losses, lower the cost of power generating, and improve voltage stability. The proposed method was tested on an IEEE 30-bus system under both normal operating settings and extreme system disturbances brought on by line outages. Under both normal and fault situations, the results show the effectiveness of the HHO-based approach in raising power system stability and operational performance when compared to those obtained using the Harmony Search (HS) technique.
