Performance enhancement of power systems with wave energy using gravitational search algorithm based TCSC devices

This paper presents an application of the gravitational search algorithm (GSA) to optimally obtain the location of thyristor controlled series capacitor (TCSC) devices to enhance the power system performance involving wave generators. Archimedes wave swing based wave energy conversion systems are used through this study, where linear permanent magnet synchronous generators are used. To examine the validation of the presented optimization method, three case studies are carried out on the IEEE 39 bus, IEEE 57 bus, and IEEE 118 bus systems. This validity is verified by the simulation results, which are performed using MATLAB program. Also a comparison is made between the GSA-based system results and that of using genetic algorithm (GA). The system performance using the GSA algorithm is better than that of using the GA.
