This paper presents a new technique to optimize the number, location, and size of shunt capacitors on a radial distribution feeder in the presence of harmonics and distortion. The optimization objective is to achieve maximum savings resulting from reduced line losses. The mathematical model devised is a mixed 0-1 polynomial program, with restrictions imposed to limit the harmonic current magnification that results from parallel resonance. A global optimization algorithm for polynomial programs is utilized to solve this formulation. The effectiveness of this state-of-the-art algorithm ensures optimality to a complex mathematical model which more accurately represents the physical problem than other formulations. The method presented is suitable for solution on a personal computer, and has yielded promising initial results.

Core and copper losses of a distribution transformer increase in the presence of harmonics and distortion. In most of the cases, an indication of total harmonic distortion is known. Expressions for the transformer core and winding losses as a function of the total harmonic distortion are obtained ex
