“…To optimize the parameters of the designed Wide Area Damping Controller (WADC) the Particle Swarm Optimization (PSO) method is utilized. The PSO is a population based stochastic optimization algorithm, prompted by social behavior of bird flocking or fish schooling [18]- [19]. In order to assess the capability of the PSO based damping controller in oscillations suppression, a nonoptimized conventional damping controller is also designed and enhanced to the main control loopof the unbalanced STATCOM to suppress the oscillations.Finally the proposed approach is prosperously applied in a 16-bus six-machine test system and various case studies are conducted to demonstrate the potential of the proposed approach.…”

FACTS devices are one of the latest technologies which have been used to improve power system dynamic and stability during recent years. However, widespread adoption of this technology has been hampered by high cost and reliability concerns. In this paper an economical phase imbalanced shunt reactive compensation concept has been introduced and its ability for power system dynamic enhancement and inter-area oscillation damping are investigated. A hybrid phase imbalanced scheme is a shunt capacitive compensation scheme, where two phases are compensated by fixed shunt capacitor (C) and the third phase is compensated by a Static Synchronous Compensator (STATCOM) in shunt with a fixed capacitor (CC). The power system dynamic stability enhancement would be achieved by adding a conventional Wide Area Damping Controller (WADC) to the main control loop of the single phase STATCOM. Two different control methodologies are proposed: a non-optimized conventional damping controller and a conventional damping controller with optomised parameters that are added to the main control loop of the unbalanced compensator in order to damp the inter area oscillations. The proposed arrangement would, certainly, be economically attractive when compared with a full three-phase STATCOM. The proposed scheme is prosperously applied in a 13-bus six-machine test system and various case studies are conducted to demonstrate its ability in damping inter-area oscillations and power system dynamic enhancement.

“…When all the particles have been moved, the next iteration will be happened. At last, the swarm, just like a school of fish that are collectively searching for food, is likely to move toward an optimum of the objective function [25,27].…”

“…Recently, the PSO algorithm emerged as one of the powerful methods in managing optimization problems. PSO is counted as a population-based stochastic optimization algorithm, duplicated from the social behavior of birds or fish [26,27]. PSO not only eliminates the deficiencies of other conventional optimization methods, but it also utilizes few parameters and is easy to use.…”

This paper deals with the capability of a static synchronous series compensator (SSSC) to attenuate the subsynchronous resonance (SSR). Two well-known controllers are designed, namely a conventional damping controller (CDC) and fuzzy logic damping controller (FLDC). These 2 damping controllers are added to a main control loop of a SSSC operating as a SSR damping controller. It should be noted that, to optimize the parameters of the CDC, a versatile optimization technique is implemented, namely particle swarm optimization (PSO). A comprehensive comparison between the 2 control methods is carried out for different operational conditions. To observe the superior performance of the proposed FLDC, many operating points and different fault types are considered. The IEEE second benchmark model aggregated with the SSSC is utilized and simulations are presented.

“…A fixed-parameter controller with classical control may thus not be effective for a UPFC [8], [9]. In such cases a flexible controller may be required, such as one based on neural networks [6], PSO [10] and robust control methodologies [11], in order to cope with system uncertainties and enhance the damping performance of a UPFC.…”

This paper proposes a unified power flow controller (UPFC)-based oscillation damping controller for use with a permanent magnet synchronous generator (PMSG)-based offshore wave farm (OWF). A novel intelligent damping controller (NIDC) was used to increase the stability of power control and improve the performance, where the proposed NIDC consists of the adaptive critic network, the Functional Link based Elman Neural Network (FLENN), and PID linear damping controller. The UPFC is used with the NIDC to OWF, which is connected to a single-machine infinite-bus to improve system stability. The PID damping controller is analysis of complex eigenvalues based on a theory of modal control. The node connecting weights of the FLENN and critic network are trained online. The proposed NIDC can be used to achieve better damping characteristics. The internal power fluctuations in the power system can also be effectively alleviated under variable wind power generation.
