Stability of power system is one of the important keys to produce high reliability of power system. The power system must maintain the stability under small or large disturbance. However, with the increasing the load demand over the years making the power system stability is vulnerable to unstable condition when there is a disturbance. Hence adding additional controller such as dual input power system stabilizer (DIPSS) is essential. DIPSS could give a signal controller to the excitation system to produce appropriate flux when there is a disturbance emerge. However, DIPSS alone is not enough to handle the small and large disturbance as DIPSS is not directly giving a damping to the source of disturbance. Hence, adding capacitor energy storage (CES) can be solution to handle this problem. CES can give a fast active power when there is load changing. This paper proposed a coordinated design between CES dan DIPSS using modified differential evolution algorithm (MDEA). Jawa-Bali Indonesian Power Grid is used as the test system. Non-linear time domain simulation is carried out to investigate the efficacy of the proposed controller method. In addition, transient kinetic energy (TKE) assessment is carried out to investigate how much kinetic energy produced by the system. From the simulation results, it is found that the proposed method giving a better stability indicated by the smallest overshoot and the fastest settling time compared to the other scenarios. Furthermore, it is found that the proposed method controller could give a smallest TKE value (0.0000004076) compared to the other scenarios.

“…Furthermore, the statistical analysis test was performed on the proposed method to show its robustness over other methods. 46 Though some promising methods using meta-heuristic algorithms have been proposed in the recent studies for tuning the parameters of SSSC and PSS, only Devarapalli et al 46 applied statistical analysis on the obtained results to draw conclusions. As meta-heuristic algorithms are stochastic in nature, statistical tests on obtained results are inevitable to draw decisive conclusions.…”

In this paper, a modified sine cosine algorithm (MSCA) is proposed and is applied to design the power system stabilizer (PSS) and lead lag compensatorbased static synchronous series compensator (SSSC) controller to enhance the power system stability. Two test systems: single machine infinite bus (SMIB) and multi-machine power system (MMPS) working under various loading conditions are taken as case studies. The objective of the work is to enhance the stability of the system by minimizing the rotor speed deviation of the generator. For this, the optimal controller parameters of PSS and SSSC are deter-
