This paper presents an approach for alleviation of network over loads in the day-to-day operation of power systems. The method used for over load alleviation is real power generation rescheduling based on relative electrical distance (RED) concept. The method estimates the relative location of load nodes with respect to the generator nodes. First congestion is observed, and then each generator’s contribution to the congested line is found out. Based on RED method desired generation rescheduling is obtained to relieve overloaded line. Cost is also a key factor which has to be considered in real power rescheduling. A case studied is carried out for modified IEEE 39-bus New England system, where power flow is found by Newton Rapson’s method and compared with operational load flow method.
