A new approach for placement of single-tuned passive harmonic filters in a power system

The purpose of this paper is to present a new method for determining locations of single-tuned passive harmonic filters in a power system. The harmonic filter planning is for controlling the system-wide voltage distortion while against individual and total harmonic distortion limits at each network bus as well as filter component limits. The planning problem is formulated as a constrained optimization problem, and is then solved to find the optimal size of each filter component. The proposed method has been tested with an actual system. Test results show that the method is effective, computationally robust, and suitable for passive filter planning in a power system.
