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).

Summary Voltage regulation at weak distribution networks and feeders imposes several challenges. The degree of complexities of the overall design and implementation is network and site dependent. In this paper, design and implementation of a thyristor controlled reactor–based static VAr compensator (SVC) system to enhance voltage regulation and avoid voltage instability are presented and discussed. The SVC system is installed for an extremely weak distribution network with long feeders in a remote area in the Kingdom of Saudi Arabia. This work is the first implementation of an SVC system in the utility's distribution network in Kingdom of Saudi Arabia. Principles of operation, overall design assessment, and protection modifications in the installation area are described. Power stage and digital control system are custom designed according to the specific network and operation requirements. The overall system is examined under steady‐state and dynamic conditions. Power system at the corresponding area with/without the compensator is simulated using PSCAD/EMTDC software. Field test results are also obtained, and the performance of the system is discussed along with the design considerations required for such installations. The various technical discussions presented in this paper highlight several practical considerations and practices that are valid in similar installations for extremely weak distribution networks around the world.

“…In addition, SVC can improve transient stability by fast exchange of reactive power with the network. Besides reactive power control and voltage regulation as SVC's pivotal functions, supplementary control blocks can be accommodated to modulate the SVC bus voltage in order to improve the damping of power system oscillations [5,6]. Various approaches have been proposed in the literature for designing a supplementary damping controller aiming at enhancing the power system stability.…”

In this paper, the optimal tunning problem of parameters of a conventional lead-lag controller (LLC) and a fuzzy logic controller (FLC) based on the static Var compensator (SVC) is considered. The solution is obtained using an improved particle swarm optimization (IPSO) algorithm. The membership functions and scaling factors of the FLC and LLC parameters are optimized using the above-mentioned technique. The proposed controllers are settled down to an SVC that is installed at the middle of a transmission line connecting a single machine to an infinite bus system. Simulation results show the superiority of the optimized FLC compared to the optimized LLC and also when the SVC is without the supplementary controller under different disturbances and loading conditions. The simulations and analyses are implemented in MATLAB environment.
