Bacteria Foraging Optimization Algorithm based SVC damping controller design for power system stability enhancement

A new method for SVC placement considering FSS limit and SVC investment cost

“…According to (13), it is clear that the minimum and maximum values of CI i are equal to 0 pu and 1 pu, respectively. Also, the value of CI i becomes less for more SVC investment costs.…”

“…Based on the characteristics of FACTS devices, different objectives have been considered in optimal locations of FACTS devices problems, such as static voltage stability enhancement [1][2][3][4][5], loss reduction [5][6][7], voltage profile improvement [5,8], enhancement of the network load ability [8,9], violation diminution of the line thermal constraints [10], reduction of the power plants fuel cost using optimal power flow [11], mitigating small signal oscillations [12,13], adequate damping in power system network with changing system conditions [14], and minimization of cost function with an economical approach [15]. Although all of the mentioned objectives improve the performance of the power system, considering unlimited FACTS devices by neglecting their cost cannot be legitimized despite the assumption in [8].…”

Optimal SSSC design for damping power systems oscillations via Gravitational Search Algorithm

“…In last few years, many researchers have posed techniques for designing SVC to enhance the damping of electromechanical oscillations of power systems, regulate the transmission voltage, and improve power quality [3][4][5][6][7][8]. The main advantage of SVCs over simple mechanically-switched compensation schemes is their near-instantaneous response to changes in the system voltage [2].…”

ACO based speed control of SRM fed by photovoltaic system

“…Fuzzy Logic Control (FLC) [5][6][7][8][9][10], Artificial Neural Network (ANN) [11,12], robust controller [13], and adaptive controller [14] have been employed to solve the problem of speed control of SRM. Moreover, optimization techniques like Genetic Algorithm (GA) [15], Particle Swarm Optimization (PSO) [16][17][18], Bacteria Foraging [19][20][21][22][23] and BAT algorithm [24] have attracted the attention in designing controller and speed control of various motors.…”
