This article introduces fractional-integral-proportional-derivative (FI-PD) cascade controller as a secondary control scheme of interconnected power system to minimize the frequency and inter area active power disturbances. First, the performance of the FI-PD controller is tested on an interconnected power system with conventional thermal-hydro units, later studies are extended on same test system integrated with wind and solar. To show the improvements achieved with FI-PD controller, classical PI, PID and fractional order PID controllers are opted for comparative assessment. The optimal gains of all the controllers are identified with magnetotactic bacteria optimizer (MBO) algorithm applied first time in automatic generation control (AGC). MBO used integral square error (ISE) as fitness function in the process of identification of optimal gain parameters of the classical and proposed controllers.<
