Damping of Low-Frequency Oscillations in a Power System, Based on Multiple-Model Optimal Control Strategy

This paper proposes a new control strategy based on multimodel linear optimization (MMLOC) to damp power system low-frequency oscillations (LFO) faster. The is used anticipate synchronous generator dynamic behavior and for generating signal uncomplicatedly. third-order model of machine considered each the models. probability model’s validity evaluated from difference between outputs same actual via Bayesian approach. To improve postfault dynamics case study system, which contains static VAR compensator, optimal controller (LOC) designed. 8th order machines in simulations represent plant as accurately possible.
