Model Reduction of Coherent LPV Models in Power Systems

This paper extends the applicability of a balancing-based reduction method to power system models that are structured into a study area, a buffer area, and a linear parameter-varying (LPV) external area. The latter is represented by a network of linear time-invariant (LTI) and LPV models and forms the target of the reduction phase. Every LPV model is built to depict a region of the power system with a variable number of active generators. The various LTI and LPV models are simplified while accounting for the presence of their respective neighbors. The adequacy of the reduction process is verified on the IEEE 118-bus system model by comparing the dynamic behavior of the reduced model and the full nonlinear model for different sets of disconnected generators.
