Improved sea lion optimization to enhance available transfer capability using thyristor controlled series capacitor

Nowadays, the utilization of Flexible Alternating Current Transmission System (FACTS) devices remains a better alternative for improving Available Transfer Capability (ATC), and it further minimizes the system loss in aggressive electrical power systems. It could minimize the cost of the new transmission line construction and also enhance the utilization rate. This paper introduces a new optimization-assisted ATC enhancement model by determining the optimal placement and compensation level of a Thyristor Controlled Series Capacitor (TCSC) device. As a novelty, a unique Improved Sea Lion Optimization (I-SLnO) model is established, which is an improved form of the conventional Sea Lion Optimization (SLnO) model. The evaluation is performed in IEEE-14 & IEEE-39 test bus systems to analyze the effectiveness of the suggested approach in terms of convergence analysis, ATC enhancement, and so on.
