Background and Objectives: In this paper, a non-typical design method of flexible AC transmission systems power oscillation damping (FACTS-POD) controller is proposed to increase the efficiency of these devices. In all of the introduced FACTS-POD devices (taking IPFC-POD as an example), the supplementary controller is designed based upon a conventional approach (i.e., based on optimization algorithms) and using a different method can be useful.
Methods: In this paper, the graduated modal decomposition control (GMDC) is utilized as a specific strategy for POD controller design. Moreover, the dynamic model of the multi-machine power system with the presence of IPFC devices has been developed.
Results: The obtained model is nonlinear; however, it is linearized around the operating point to design the controllers. The overall paper's structure is based upon the two scenarios, in the first of which conventional method for IPFC-POD design has been analyzed there upon the result compared with the introduced method in the second scenario. Finally, to ascertain responsive of the designed controller to load changes and stability of the system, the probabilistic sensitivity indices (PSIs) are investigated over a large set of operating conditions. As a verification, the time-domain simulations on a 10-machine power system emphasize the analysis of dynamic results and their information under the considered conditions.
Conclusion: In general, the specific purpose of this paper is to enhance of the dynamic stability of concerned inter-area modes. The proposed method, especially using GRSA, offers better stability characteristics than the results of previous methods.
