Thus, considering these economic aspects, many controllers are proposed to guarantees their performances. The most studied strategy is the classical PID controller. However, its performance is limited due to the nonlinear model and the difficult wind speed form, which inflict many uncertainties. To solve these drawbacks, an advanced controller named Type-2 Fractional Order Fuzzy PID (T2-FOPID) controller is suggested in this paper to improve the exigence controls. Meanwhile, an efficient optimization technique named the Salps Swarm Algorithm (SSA) has been introduced in order obtaining the best controller parameters. The efficiency of the proposed controller is tested to the 10 kW-WT under various wind speed scenarios. The derived results explicitly indicate that the proposed strategy outperforms the PID controller and other controllers, in terms. the minimum of error, the overshoot and the settling time.

The major proposal is that the effective property of PID and high characteristics of SMC are combined to eliminate the chattering effect of SMC in order to generate best control signal to the excitation system. The robust design of SMC-PID has been employed to enhance the power system stability and further to damp out strongly the system oscillations that caused by the disturbances. The proposed proposition is evaluated on Single Machine Infinite Bus (SMIB) power system under different perturbations with prespecified operating condition. The simulation results have demonstrated the high performance of mentioned controller that attained best results compared to various controllers. Keywords— PID, Power system stability, PSS, SMC, SMIB power system.

The comparative study shows that the GA is more effective. A model based on a hybrid approach that combines CSM and the GA is proposed to calculate the electric field created by an overhead extra high voltage power line. The resulting field levels were compared with exposure values set by the ICNIRP and IRPA standards. The results show that these levels are less than the limit recommended by these standards. The simulation results of electric field intensity values are compared with those obtained from polarisation ellipse method. A good agreement has been reached.

The aim of this study is to find robust controller for demonstrating the availability of the proposed controller, and to achieve best desired output. Here, we have chosen SMC as one of the most effective control methodologies for adjusting the states of the system to their preferred values to supply the excellent damping under severe disturbances. The problem of SMC-FOPID design is transformed to an optimization problem based on performance index, which is Integral of the Time Weighted Absolute Error (ITAE). Where, BA has been employed to adjust the optimal controller parameters. The effectiveness of SMC-FOPID has been tested on a Single Machine Infinite Bus (SMIB) power system under different cases, including operating. The performance of SMC-FOPID controller in power system is compared with a conventional PSS. The simulation results greatly indicate the validity and effectiveness of the proposed controller, and superior robust performance for improvement power system stability compared with the PSS controller for each case.

The proposed approach combines ANN and GA search for setting the optimal parameters of a PSS. The performance of the proposed Neuro-Genetic PSS (NGPSS) under small and large disturbances, loading conditions and system parameters is tested. In fact, simulation results show the effectiveness of the NGPSS to damp out the system oscillations. Moreover, the performance and robustness of the proposed PSS for different operating conditions are more acceptable. Hence, it can be used for online control purposes to guarantee an optimal angular stability of the power system.

This hybridization is based a combination between stochastic Genetic algorithm (GA) methods and deterministic methods (gradient); it is called GA-GR, and even between themselves stochastic methods genetic algorithm and simulated annealing (GA-SA). The proposed approach is used for a multi-objective function based on the real part of eigenvalues and the damping factor, to search for optimal stabilizer parameters. To examine the effectiveness and robustness of this tuning approach in enhancing the stability of power systems, modal analysis and nonlinear simulations have been carried out on New England/New York interconnected network system 68-bus, 16-machine power system.

The PSSs parameter tuning problem is converted to an optimization problem which is solved by BAT search algorithm. An eigenvalues based objective function involving the damping factor, and the damping ratio of the lightly damped electromechanical modes is considered for the PSSs design problem. The performance of the proposed BAT based PSSs (BATPSS) has been compared with Genetic Algorithm (GA) based PSSs (GAPSS) and the Conventional PSSs (CPSS) under various operating conditions and disturbances. The results of the proposed BATPSS are demonstrated through time domain analysis, eigenvalues and performance indices. Moreover, the results are presented to demonstrate the robustness of the proposed algorithm over the GA and conventional one.
