Reactive power compensation by a linear programming technique

Abstract

This article presents a method of optimizing the reactive compensation used in power systems to establish acceptable voltage profiles during period of abnormal loads and during foreseeable contingencies. The system equations, which are nonlinear, are first approximated to a linear form, and then linear programming technique is applied to obtain the quasi-optimal solution. An iterative procedure is then used to obtain results of acceptable accuracy. The main features of the proposed method are that both inductive and capacitative compensation is optimized and that the busbars where compensation is applied, can be selected to suit the user's operating constraints. © 1981.
