Abstract

Distribution system planning, operation and control is considered to be one of the challenging tasks to meet the increasing load. Operating distribution system at its maximum limits is not a suggestible solution whereas the economic burden must also be considered. In this regard, new methodologies and procedures are required to be implemented to increase the power transfer capability of existing substation. One of such methodologies is reconfiguration of distribution lines. Further, the reconfiguration of lines is not proper in case of unbalanced and unsymmetrical distribution system where the existence of all phases is not absent. For this type of systems, in order to enhance the system performance, a new methodology based on phase reconfiguration along with phase decoupled load flow solution methodology is presented. In this method, the unbalanced distribution system is separated into self and mutual networks. Using phasor representation, the final voltages are calculated. Using this, the computational burden is decreased and also the accuracy of solution is increased. This method is tested on standard IEEE-13 node system with supporting illustrations.
