Comparative study of SBOAs on the tuning procedure of the designed SMPI controller for MIMO VSP/HVDC interconnected model

This paper presents a new application of advanced SMPI controller for newly introduced interconnected dynamic system with VSP based HVDC links frequency control problem. work an outgrowth analysis about the Swarm – Based Optimization Algorithms (SBOAs) in tuning process Multivariable Proportional Integral (MPI) controller, which is called swarm MPI (SMPI). PSO, GOA and GWO algorithms are used designed SMPI. The model added mitigation dynamics emulating virtual inertia. proposed enhancing performance this system’s states during contingencies they compared conventional controller. Deviation characteristics step function MIMO transfer considered as common index algorithms. On other hand, role to stabilize such while minimizing associated cost function. Matlab simulations next performed Nyquist’s stability anslysis demonstrate how tuned can remarkably improve deviations damping inter-area oscillations excited fault. enhancement more obvious especially when inertia emulation using method.
