Abstract:
Active Power Line Conditioners (APLCs) are
considered the most efficient device for mitigation of power
system harmonics. In this paper, a problem of allocation
and sizing of multiple active power-line conditioners
(APLCs) in distorted power distribution systems is handled
with novel formulation. The utilized objective function
comprises two main factors such as reduction of total
harmonic distortion and the total cost of APLCs. The
formulated problem is solved by four different optimization
techniques GA, PSO, Hybrid GA-PSO and DE. To evaluate
the competence of the proposed formulation, the IEEE 18-
bus and 69 bus distorted distribution test systems are
employed and investigated with various number of APLCs
placement. These cases are based on the discrete and
limited size for APLCs, requiring the optimization method to
solve the constrained and discrete nonlinear problems.
Therefore, all the evolutionary algorithms used utilize an
integer optimizer. Simulation results confirmed the
capability and effectiveness of the proposed formulation and
DE algorithm works well in the allocation and sizing of
multiple APLCs in a test power system compared with other
heuristic algorithms.
