The fact that the bulk of power system losses occurs at the distribution level triggered interests in analyzing the cost of losses and methods that reduces these losses. Today the loss reduction capability of shunt capacitors has been receiving more attention from distribution engineers who have long been aware of the need for reactive power control on the distribution system. Shunt capacitors would be most beneficial in minimizing losses on primary distribution feeders through optimal placement programs that utilize methodologies based on robust but rigorous load and feeder modeling procedures to assist in attaining this goal. One major contribution of this research is to develop a new methodology for energy and peak power loss minimization via fixed and/or nonsimultaneously switched capacitor bank placement on three phase radial feeders. This new methodology is based on realistic modeling procedures that account for feeder and load unbalance; the effects of ground wires and earth-return paths are also accommodated within the models. Power-invariant transformations are introduced to decouple the actual three phases and thereby yield three equivalent single phases with a common definition of feeder length. Another major contribution is the development of a new modeling technique for treating laterals allowing for a more accurate representation of physically existing feeders.
