The control of power flow along transmission line is becoming interesting in the power systems. Regulating transformer is used as a convenient and practical way of controlling power flow in systems, network. The presence of regulating transformer in electrical system enhance the load flow solution; also redistributes, control the bulk power flowing along the transmission line. The purpose of this proposed model is to incorporate regulating transformer and phase shifter in order to normalize and control voltage stability margin. A properly designed and operated power system should, therefore, meet the following fundamental requirements: The system must be able to meet the continually changing load demand for active and reactive power. Unlike other types of energy, electricity cannot be conveniently stored in sufficient quantities. Therefore, adequate “spinning” reserve of active and reactive power should be maintained and appropriately controlled at all times. The system should supply energy at minimum cost and with minimum ecological impact. The “quality” of power supply must meet certain minimum standards with regard to the following factors; Constancy of frequency; Constancy of voltage; and level of reliability.[1]
