“…For obtaining the optimization parameters using the ABC algorithm the following steps must be taken: 1-The system data and ABC algorithm parameters like the colony bees (number of employed bees + onlooker bees) (Np), the limit value and the number of cycles (max cycles) are specified. 2-Producing the initial conditions for each employed bee (determining the initial conditions for optimization parameters᾽ values) Each individual bee from the population is randomly given a value observing the limitations mentioned in equations (10) and (11). 3-The attraction of the initial random values is determined by replacement in the Formula (7).…”

“…STATCOM can used to maintain the magnitude of the bus voltage constant [9,10]. Power system stabilizer (PSS) and FACTS controllers are acceptable solutions for voltage and oscillatory instability problems, since these controllers increase loading margins and provide additional system damping [11,12]. PSS is widely used in existing power systems in order to damp out power system oscillations [13,14].…”

This paper develops a design procedure for simultaneous coordinated designing of the static synchronous compensator controller parameters (STATCOM) and power system stabilizer (PSS) in multimachine power system. The artificial bee colony (ABC) algorithm is employed to search for optimal controllers parameters. ABC algorithm is a collective intelligence based on optimization algorithm inspired by the feeding behavior of bees in finding food. Rapid convergence and high precision are the capabilities of this algorithm which in this study to demonstrate its effectiveness and robustness, a two zone-four machines system is used and analyzed through non-linear simulation of time-domain and the results are compared with particle swarm optimization (PSO) algorithm. The optimization after a large turbulence shows that the coordinated design of the STATCOM and PSS controllers' parameters using the ABC algorithm considerably improves the system stability together with rapid damping of the system fluctuations as compared to the state without optimization. On the other hand, the optimization results using the ABC algorithm shows the superiority of this method over the PSO algorithm.

“…In order to provide a stable system operation, the proposed scheme aims to minimize harmonic injections by SVC installations by using the fuzzy logic approach for switching. Furthermore, the capacitor banks are designed in binary order, and more focus was given to the optimum operation of the reactor (Trinh and Lee 2013;Velásquez and Lara 2018). As a result, at PCC, minimum harmonic injection within the standard limit from the SVC side is observed at a steady state.…”

In power distribution network, more and more people are worried about equipment failures and malfunctions caused by fluctuating loads and system harmonics due to poor power quality. The presence of harmonics can shorten the equipment's service life. There is a strong link between the energy use and the environment. Major part of power demand is supplied from thermal power stations which produce more carbon emissions as the power plant uses more fuel to generate the electricity. The effective utilization of transformer capacity is achieved by minimizing system losses and improving voltage regulation in the distribution system. Many techniques are used to address this issue, ranging from several power factor correction systems to passive and active harmonic filtering. Although distribution static compensator (DSTATCOM) is a perfect solution to solve this problem, they are expensive and have more complexity as a view against static var compensators (SVCs). This study aims to provide optimal approach for SVC switching in unbalanced operation of the distribution networks. In present work, the SVC is arranged in thyristor binary switched capacitors (TBSC)-thyristor-controlled reactor (TCR) configuration. The capacitor banks are set in binary sequence, and the optimal size reactor is decided. The TCR in SVC inherently generates the harmonics. The fuzzy logic approach is used to solve this non-linearity by determining the optimal triggering delay angle of the thyristor in TCR. This results in significant reduction in harmonics injected by the SVC. The strategy is appealing to improve efficiency of power distribution networks and thereby save natural resources required to generate electricity from thermal power stations.
