Abstract The problem of LFC design is considered as a very imperative issue facing the researchers in the power system operation. This problem is represented in the selection of the suitable controller. Thus, the proper tuning of the controller parameters by an efficient method is required for getting the better performance of the controller. Furthermore, the simulation of power system with co-operative strategy is demanded to reduce the computation time and the accumulation operation which may be obstacles the performance of the system in real time operation. This thesis applied the MPC, a new smart supervisor controller, MPC with SMES and MPC with PHEV to solve the LFC problem in a linear and nonlinear interconnected two, three area power system. Furthermore, the proposed controllers were applied on a smart grid including nonlinear interconnected two, three area with RES penetration and load fluctuations. The parameters of the candidate controllers were selected by the using of the ICA, GSA and BIA as new AI techniques based on different objective functions. The performances of the candidate controllers were compared with the performance of the conventional PI controller. The proposed systems were simulated by parallel processing and multi-parallel agents’ strategies. Chapter7 CONCLUSIONS 121 7.2 Contributions The contributions of this thesis are summarized in the following: 1- The application of MPC, a new smart supervisor controller, MPC with SMES and MPC with PHEV on a linear and nonlinear interconnected two, three area power system and smart grid with RES penetration and load fluctuations. 2- The optimal tuning of MPC, MPC with SMES and MPC with PHEV parameters by the using of the ICA, GSA and BIA. 3- The consideration of interconnected two, three area power system nonlinearities which represented in GRCs, GDBs, and the communication time delay and boiler dynamics. 4- The comparison between the ICA, GSA, and BIA in the optimal selection of MPC, MPC with SMES, and PHEV parameters based on the applying of different objective functions and select the best one. 5- The investigation of the performance of each applied AI technique with the increasing of the system complication and the changing of the objective function. Thus, it is proven that the performance of an AI technique may be the best in a simple system but not the best in a complicated system. Furthermore, it has been shown that the performance AI technique may be the best with an objective function but not the best with another objective function or not valid with an objective function. 6- The testing of the best controller under the change of load disturbance, time delay and the parameters uncertainties. 7- The simulation of the proposed system by parallel processing and multiparallel agents’ strategies for reducing the computation time and the accumulation operation. 8- Application of a new smart supervisor controller to combine the advantages of two different controllers. |
