TL;DR: It has been demonstrated that SGA tuning PID controller improves the performance in a large compared with FA tuned PID controller and the robustness of the suggested method (SGA with PID controller) for two-area with six unit power system in AGC.
Abstract: This paper proposes a new Search Group Algorithm based PID controller, to deal with Automatic Generation Control of two-area with six unit power system. The supremacy of SGA tuned PID controller is being shown using the comparative study with Firefly Algorithm (FA) optimization method for the same test system using ITAE as an objective function. It has been demonstrated that SGA tuned PID controller improves the performance in a large compared with FA tuned PID controller. Furthermore variation in nominal values of operating load condition and system parameters with the position of step load perturbation is being carried out to achieve sensitivity analysis. From the result of sensitivity analysis it clearly depicts the robustness of the suggested method (SGA with PID controller) for two-area with six unit power system in AGC. Finally for better investigation, the proposed method is also examined by applying randomization in step load.

TL;DR: This work establishes its superiority over published results with conventional controller structures by taking the same test conditions by applying differential evaluation (DE) optimization method, and is validated by the MATLAB simulation results.
Abstract: In the present research work, two-area thermal power plant structure is studied with cascade tilt-integral-tilt-integral-derivative (CC-TI-TID) controller. The controller gains are optimized by applying differential evaluation (DE) optimization method. In load frequency control (LFC) studies the role of controller is very important to ensure good quality of power supply. Different controller structures have been proposed for different research problems. Yet, there are further scopes for new controller structures. The proposed approach establishes its superiority over published results with conventional controller structures by taking the same test conditions. It is validated by the MATLAB simulation results.

TL;DR: Simulation study confirms that the proposed SGA technique is better as compare to FA technique for the system and the supremacy of SGA tuned PID controller is projected with a comparative empirical result over recently published firefly algorithm (FA) optimized technique tuned PID Controller.
Abstract: A novel search group algorithm (SGA) technique with PID controller is proposed for an application toward multi-area interconnected power system-based automatic generation control (AGC). A reheat thermal power system over three unequal areas is considered. The system includes the nonlinearity parameters such as GRC and GDB. The supremacy of SGA tuned PID controller is projected with a comparative empirical result over recently published firefly algorithm (FA) optimized technique tuned PID controller for the similar multi-area power system which is interconnected. Simulation study confirms that the proposed SGA technique is better as compare to FA technique for the system.

TL;DR: An Adaptive Differential Evolution (ADE) algorithm based cascade PD-PI controller is proposed for Automatic generator controller (AGC) of thermal system and it is clearly observed that the proposed controller simulation results provide better response compare to published results.
Abstract: An Adaptive Differential Evolution (ADE) algorithm based cascade PD-PI controller is proposed for Automatic generator controller (AGC) of thermal system. Initially, a two equal area reheat interconnected thermal power system is investigated and gain values of PD-PI controller is tuned by ADE technique employing an Integral of time multiplied absolute error (ITAE) based criteria. The performance result of suggested PD-PI controller is correlated with newly published approaches such as Firefly algorithm (FA) based PI/PID controller for same test model. It is clearly observed that the proposed controller simulation results provide better response compare to published results. Lastly, the robustness of suggested controller is inspected by various time delays (TD), random step load pattern in the system and also evaluated stability analysis in terms of phase margin and gain Margin.

TL;DR: A 2 degree of freedom tilt integral derivative controller with filter (2DOF-TIDF) is suggested for frequency regulation in multi-area interconnected system and the advantage of the suggested method is verified by comparing the results with TIDF controller.
Abstract: In the present work, a 2 degree of freedom tilt integral derivative controller with filter (2DOF-TIDF) is suggested for frequency regulation in multi-area interconnected system. Firstly a three-area thermal system having nonlinearities is considered and 2DOF-TIDF controller is being implemented in all areas. The parameters of the controllers used are optimized using Differential Evolution (DE) technique. To improve the system’s performance, Thyristor Controlled Series Compensator (TCSC), Unified Power Flow Controller (UPFC) and Static Synchronous Series Compensator (SSSC) are used and the performance of the proposed controller in the occurrence of these FACTS devices is investigated. The advantage of the suggested method is verified by comparing the results with TIDF controller. At last sensitivity analysis is performed in order to confirm the healthiness of the system.
