Abstract :
Harmonics are one of the most important
issues in electric power systems. A passive LCL filter is
effectual equipment for impeding harmonic pollution and
heightening power quality. A passive LCL filter is
usually utilized to interconnect a power electronic
converter to a system. The design of passive LCL filter is
not simple because of high compensating bandwidth and
variable frequency modulations involved in active filters.
Conventional approaches for the design of passive filters
depend on the experiences and single technology
criterions, which are difficult to achieve the optimal
solution. An optimal design technique based on
Imperialist Competitive Algorithm (ICA) is proposed in
this paper. The minimum Total Harmonics Distortion of
voltage (THD) is used as constraint condition. The
proposed method shows the application of ICA method to
search optimal passive LCL filter parameters. The
proposed method has different capability like, easy
implementation and good computational efficiency. The
results are compared with other evolutionary algorithm
like PSO and the advantage of proposed method is
revealed.
