AN INTERACTIVE PROCEDURE FOR THE COORDINATION OF DECOUPLED VAR VOLT CONTROL IN RADIAL-DISTRIBUTION SYSTEMS/

This paper deals with mutually connected problems of reactive power co mpensation and voltage control in radial distribution systems. The pap er presents a simple iterative procedure for optimal coordinates of ac tions of main means for reactive compensation (shunt capacitors) and v oltage control (variable turn ratio transformers), within the decouple d solution of these two subproblems. The procedure is based on the sta tic optimization, specified as a non-linear programming-type problem. The paper presents the derivation of a method for the solution of spec ified control problems and gives an illustrative application of this m ethod on the test example of a one-source radial distribution system, consisting of 53 nodes and 52 branches.
