Abstract:

This paper presents the analysis of automatic generation control (AGC) of an interconnected bilateral two area thermal- thermal system. As an interconnected power system has large number of area frequency oscillation. To compensate these oscillations, the additions of small capacity super conducting magnetic energy storage (SMES) unit in area 1 or 2 are studied. The optimal values of the integral gain settings are obtained by using the linear quadratic regulator. Analysis reveals that SMES unit is fitted in either area improves the dynamic performance to a considerable extent following a load disturbance in either of area. The results obtained by using LQR and compared by with or without SMES.
