The stability is the most important goal in any electrical network, and the control of this network is a part of the stability organization. This article presents application of three optimization algorithms, which are Henry Gas Solubility Optimization, Grey Wolf Optimization, and Ant Lion Optimization, to obtain the PID controller parameters for Static var compensator SVC connected to Single Machine Infinite Bus (SMIB) system. The suggested optimization techniques were used to choose the most accurate PID parameters to enhance the system stability. And then applied the proposed optimization algorithm which gives the best value of J-obj in the PID controller variables with the Static VAR Compensator's (SVC) variables to get the most suitable values for them which leads to more and faster stability than without the SVC then it compared with the Power System Stabilizer (PSS). So that the importance of installing optimized SVC based PID controller is evident.
