This paper describes a unified automatic generation control (AGC) scheme coordinating EDC (Economical Load Dispatching Control) and LFC (Load Frequency Control). So far, in absorption of the load fluctuations occurring on power systems, both of EDC and LFC systems have been considered separately each other. By coordinating both control systems, undesirable system behaviours are avoided. The responses of frequency deviation, turbine power fluctuation and tie-line power flow deviation are smoothed using the proposed AGC scheme.The background theory is based on servo-type optimal control theory. The structure of the proposed control method is a decentralized type. So, the implementation in multi-area power systems is easy.The effectiveness of the proposed unified AGC is illustrate_??_ by an example, and the simulation results on three-area power systems show that the method is encouraging. In this paper, some of the problems associated with the application of this method to the multi-area AGC are discussed.
