Automatic generation control of an interconnected thermal system using a new classical controller: A preliminary study

Robust two-degree-of-freedom controller for automatic generation control of multi-area system

“…The use of PIDD controllers not only improves stability but also helps to achieve fast response in the system compared to PID and PI controller [12]. However, the derivative operator(s) in the PIDD controller will boost disturbances drastically which causes system instability.…”

“…Recently, authors in Ref. [12] has proposed another novel SDF based classical controller named as Proportional plus Integral plus Double Derivative (PIDD) for AGC system and surprisingly it is seen that proposed PIDD controller provides far better responses than the reported IDD controller. However, their investigation was limited to two-area thermal system.…”

“…The problem of controlling generator output in response to changes in system frequency and tie-line power interchange is known as automatic generation control (AGC). There has been considerable research work attempting to propose better AGC systems [1][2][3][4][5][6][7][8][9][10][11][12]. Numerous control methodologies such as classical controller [2,3], optimal control [4], adaptive control [5], fractional order controller [6,23,24], fuzzy logic control [7,8], and neural network controller [9,10] had been proposed by researchers over the past decades.…”

Automatic generation control of multi-area system using two Degree of Freedom Fractional Order PID Controller: A preliminary study

“…It is seen that IDD controller provides much better responses compared to aforesaid controllers under different operating conditions. Transfer function model of three-area thermal system Recently [6] had introduced a new IO based classical controller named as Proportional plus Integral plus Double Derivative (PIDD) controller in AGC of two-area thermal system. Their investigations concluded that the proposed PIDD controller can outperform the conventional I, PI and PID controller as well as IDD controller.…”
