The stability of the power system is a top priority for electricity producers. Good stability will also provide good power quality for consumers. However, disturbance in the stability of the electric power system often occurs. An example of stability disturbance is voltage drop caused by large load entering the electric power system. The large load absorbs a lot of power, resulting in voltage drop on the other bus. The purpose of this paper is to improve the voltage drop using Static Var Compensator (SVC). In the method, SVC performance is optimized using the Hybrid Artificial Bee Colony (HABC) algorithm. Contribution of the ABC is to find the optimal capacitor and inductor parameters for VSC. In addition, several scenarios for voltage improvement are made for comparison of SVC performance after optimization. The first scenario, using conventional SVC. The second scenario, using SVC with Artificial Bee Colony (ABC). The third scenario, using SVC with Genetic Algorithm (GA). The fourth scenario, using SVC with HABC. The application of ABC, GA, and HABC can improve SVC performance. Algorithm which gives the best results is HABC. HABC is able to increase the bus voltage above 97% as a whole. It is also able to reduce the losses of active power and reactive power to be the smallest.
