VOLT VAR CONTROL ALGORITHM FOR MODERN DISTRIBUTION MANAGEMENT-SYSTEM

In this paper, a centralized Volt/Var Control (VVC) algorithm for Dist ribution Management System is presented. The algorithm is based on the oriented discrete coordinate descent method and takes into account al l the optimization objectives of interest to distribution system analy sis: minimum power loss, power demand or the number of control steps t o keep the system within constraints. Although the optimization method used belongs to the traditional class of combinatorial integer progra mming, the algorithm provides good speed for real-time application. Nu merical examples illustrate how well the VVC algorithm works for the d ifferent types of objective functions and it's advantages in compariso n with other possible optimization strategies.
