“…The approach of [24] is to minimize VTHD on the load by adjusting and while keeping the constant and construing the cost of the compensating circuit to a series of fixed values. This can be accomplished by minimizing a total cost function , which represents a combination of VTHD and (20) where is an arbitrary factor to convert to cost.…”

The objective of this paper is to propose a new approach for designing passive compensators by using the penalty function method as an optimization tool. The performance of the cost-effective passive compensator for a constant load depends on the appropriate inductor and capacitor selection. Several design methods are reviewed and a novel design methodology is proposed in this paper. By using the proposed method, the designer can quickly find appropriate parameter values to meet the desired circuit performance. Simulated results show that an appropriate combination of the inductor and capacitor selected by the proposed method can meet the desired power-quality requirement. Different cases of design examples are shown in this paper to verify the performance of the proposed design methodology.

“…Consequently, maximum power factor is not exactly equivalent to minimum apparent power or minimum source current. In order to avoid resonant conditions and further improve performance, a detuning reactor L in series with the capacitor C (LC compensator) has been studied [8][9][10][11][12][13][14]. However, to achieve the highest possible power factor and simultaneously meet minimum operational and power quality requirements a sufficiently complex compensating circuit has to be designed [15,16].…”

“…The fi lter design has become essential for systems. The problem of designing a harmonic fi lter has been conventionally by trial and error approach, In the recent decade, various formulations for a more systematic approach to harmonic fi lters design have been developed [1][2][3][4][5]. Although eff ective in eliminating the harmonic, these methods did not consider the cost of fi lter elements, they also did not address whether or not the issue of the size of fi lters could adhere to the system specifi cations.…”

In this paper, we formulate the design harmonic fi lter problem taking by considering investment cost and operational constraints. System quality can generally be achieved by installing harmonic fi lters in industry systems, thereby reducing the harmonics. Users prioritize the performance and cost of fi lters as primary concerns. This new formulation uses a combinatorial optimization problem with a non-diff erentiable objective function. A solution methodology based on an optimization technique-simulated annealing is also proposed to determine the size of fi lters with minimum cost. As a result, the proposed solution methodology can off er the optimal size and minimum cost of design fi lters. In conclusion, a solution algorithm is developed to derive the global optimal solution and test on a 69kV industrial power system with highly promising results.
