A modified fruit fly optimization algorithm (MFOA) combined with a probabilistic approach are proposed in this paper to coordinate and optimize the parameters of power system stabilizers (PSSs) and static VAR compensator (SVC) damping controller for improving the probabilistic small-signal stability of power systems with large-scale wind generation, taking into consideration the stochastic uncertainty of system operating conditions. It is generally accepted that there is a threat to the stability of power system with penetration of wind farm. In addition, the stochastic fluctuations of wind generation make PSSs tuning more difficult. In this paper, PSSs and SVC damping controller are employed for suppressing local and inter-area low frequency oscillation. In order to eliminate the adverse effect between PSSs and SVC damping controller, the MFOA based on the probabilistic eigenvalue is applied to coordinate and optimize their parameters. The effectiveness of the proposed approach is verified on two test systems.Index Terms-Modified fruit fly optimization algorithm (MFOA), power system stabilizer (PSS), probabilistic small-signal stability, static VAR compensator (SVC).

“…While the main purpose of SVC is for voltage control, a proper supplementary control signal to SVC voltage control loop can provide damping to inter-area oscillations [2]. In literature, SVC damping controller has been designed using locally measured transmission line-current magnitude [3] and locally measured active power [4], [5] and generator angular speed [6]- [8]. But no considerable effort has been made to use wide area signals as the inputs.…”

“…The primary application of the SVC is to maintain the bus-bar voltage at or near a constant value. The SVC is equipped with a voltage regulator that provides synchronizing torque while damping torque contributions are small [2], An additional damping controller is necessary for extra damping. On the other hand, the common use of the thyristor controlled series capacitor (TCSC) devices is to regulate the power flow through the transmission line in which it is installed.…”
