New tool for reactive power planning

Abstract

A new tool for planning reactive power compensation is presented. It is based on the capability chart of the power system, which describes the domain of allowable operation of the system in the plane of total active and reactive load demand. Reliability concepts are used to describe the ability of the power system to face the load; the stochastic approach is adopted because load demand is fundamentally uncertain. Results for the AEP 14 bus test system are presented.
