The causes of accumulation of inadvertent interchange energy are investigated using two area analysis. This analysis is based on vector decomposition and is illustrated on the two dimensional ( epsilon , I//i) plane. Accumulation of inadvertent interchange energy I//i and the decomposed vector components caused by areas i and r, ( epsilon //i, I//i//i) and ( epsilon //r, I//i//r), are investigated through the computer simulation of a six-area system. The selective participation in time error correction and the effect of introducing frequency offset are considered. It is shown that the present two-step correction scheme of time error and inadvertent interchange energy can be modified to reduce unnecessary regulation.
