PSO - PI Based DC Link Voltage Control Technique for Shunt Hybrid
Active Power Filter
ABSTRACT
In power systems, the intensive use of nonlinear loads
causes several power quality problems such as current harmonic pollution. In
order to reduce the current harmonic pollution, the shunt hybrid active filter
(SHAPF) is the best solution effectively. In shunt hybrid active filter systems
SHAPFs, the design of dc link controller is a significant and challenging task
due to its impact on the performance and stability of the overall system. The
main contribution of this paper is that the particle swarm optimization (PSO)
algorithm is applied gains for PI controller which can result in the improved response
in terms of response time and overshoot. In proposed control method, the
performance results of harmonic compensation are satisfactory. Theoretical
analyses and simulation results are obtained from an actual industrial network
model in PSCAD. The simulation results are presented for proposed system in
order to demonstrate that the harmonic compensation performance meets the
IEEE-519 standard.

CONCLUSION
The intensive use of nonlinear loads
causes several power quality problems such as current harmonic pollution. In
order to reduce the current harmonic pollution, the shunt hybrid active filter
(SHAPF) is the best solution effectively. In shunt hybrid active filter systems
(SHAPF)s, the design of dc link controller is a significant and challenging
task due to its impact on the performance and stability of the overall system.
On account of the limitations between existing literatures, the purpose of this
paper is that PSO algorithm has been proposed to adapt the dc link controller gains
of the SHAPF. In this paper, the particle swarm optimization (PSO) algorithm is
applied gains for PI controller which can result in the improved response in
terms of response time and overshoot. In proposed control method, the
performance results of harmonic compensation are satisfactory. Theoretical
analyses and simulation results are obtained from an actual industrial network
model in PSCAD. The simulation results are presented for proposed system in order
to demonstrate that the harmonic
