AGC Automatic Generation control ACE Area Control Error

Abstract—In power system, the main goal of load frequency control (LFC) or automatic generation control (AGC) is to maintain the frequency of each area and tie- line power flow within specified tolerance by adjusting the MW outputs of LFC generators so as to accommodate fluctuating load demands. In this paper, attempt is made to make a scheme for automatic generation control within a restructured environment considering effects of contracts between DISCOs and GENCOs to make power system network in normal state. This scheme is tested on two area system with considering deregulation using MATLAB simulink tool. The results are shown in frequency and power response for two area AGC system in restructured environment.
