FDM based MOP to Attune IPFC POD Controller and Dual-Input PSS in order to Improve Power System Dynamic Performance

摘要

With the presence of Interline Power Flow Controller (IPFC), three definite classes of the Power System Stabilizer (PSS) have been evaluated as: a) Conventional PSS (CPSS); b) dual-input PSS; and c) accelerating power PSS mode! (PSS2B). The design procedure of coordination is expressed as a Multi-Objective Problem (MOP) and the coordination is focused on concurrent selection of the controllers parameters utilizing Nonlinear Time-Varying Evolution (NTVE) based Multi-Objective PSO (MOPSO) algorithm. A Fuzzy Decision-Making (FDM) approach is proposed for finding best compromise solution from the set of Pareto-solutions obtained through MOPSO-NTVE. Finally, in a system having the IPFC, comparative analysis of the results obtained from application of the dual-input PSS, PSS2B and CPSS is presented. The simulation results show that the dual-input PSS & IPFC and PSS2B & IPFC coordination provide a better performance than the conventional single-input PSS & IPFC coordination.
