The capacitor sizing problem is a special case of the general capacitor placement problem. The problem is to determine the optimal size of capacitors placed on the nodes of a radial distribution system so that the real power losses will be minimized for a given load profile. This problem is formulated as a nonlinear programming problem. The ac power flow model of the system, constraints on the node voltage magnitudes, and the cost of capacitors are explicity incorporated in the formulation. A solution algorithm, based on a Phase I - Phase II feasible directions approach, is proposed. Also presented are a new formulation of the power flow equations in a radial distribution network and a numerically robust, computationally efficient soltuion scheme. This solution scheme is used as a subroutine in the optimization algorithm. Test results for both the capacitor sizing problem and the power flow solution schemes are presented.
