This paper is aimed to present a strategy to compensate the deviations of the tie line power flow among control areas after a load change in some of them. In an actual power system, the area control error (ACE) is not necessarily a measure able to correct both the deviations of frequency and the tie line flows. In this paper a hierarchical strategy to carry out this purpose is proposed. It is assumed that each area has at least one generator in charge of carrying out the automatic generation control (AGC). A detailed state space model is used without necessity of carrying out many of the assumptions that commonly are considered for this type of studies. Results of simulation are exhibited that show the applicability of the proposal.
