It is shown that for any one control area, the rest of the interconnection can be considered as one equivalent area. System time error and inadvertent interchange energy of an area are considered as a vector with two coordinates. This vector can be decomposed into two vector components: a component caused by the area itself, and a component caused by the rest of the interconnection. This concept of vector decomposition can be illustrated on the two-dimensional Cartesian plane called the ( epsilon ,I) plane. Some properties of the effect of the control actions on system time error and inadvertent interchange energy are discussed. Control actions investigated are the automatic generation control actions and/or corrective control actions in and/or outside an area.
