State Residualisation and Kron Reduction for Model Order Reduction of Energy Systems

نویسندگان

چکیده

Greater numbers of power electronics (PEs) converters are being connected to energy systems due the development renewable sources, high-voltage transmission, and PE-interfaced loads. Given that electronics-based devices synchronous machines have very different dynamic behaviours, some modelling approximations, which may commonly be applied run transient simulations transmission systems, not optimal for future grids. Indeed, systematic utilisation phasor approximation lines, implemented in most simulation programs, is increasingly appropriate anymore. In order avoid requirement full electromagnetic simulations, can resource-demanding time-consuming, this paper proposes a combination an event-based state residualisation Kron reduction technique. The proposed technique has advantage allowing accurate based on number variables, depending observed considered events, tolerated error, along with simplifying equations accelerated simulations.

Fast Model-order Reduction for Mechatronic Systems

We present recent advances in the mixed symbolic and numeric model reduction techniques for automatically extracting the dominant system behavior of multiphysical systems. A unique feature of our approach is to compute approximated symbolic formulas for linear and nonlinear system characteristics, rigorously reducing the complexity of symbolic expressions while controlling a user-given error bo...

Model reduction of second order systems

where the matrix M ∈ RN×N is assumed to be invertible. Models of mechanical systems are often of this type since (1.1) then represents the equation of motion of the system. For such a system M = MT , C = CT and K = KT are respectively the mass, damping and stiffness matrices, f(t) ∈ RN×1 is the vector of external forces, and x(t) ∈ RN×1 is the vector of internal generalized coordinates (see [4]...

Kron Reduction of Generalized Electrical Networks

Kron reduction is used to simplify the analysis of multi-machine power systems under certain steady state assumptions that underly the usage of phasors. Using ideas from behavioral system theory, we show how to perform Kron reduction for a class of electrical networks without steady state assumptions. The reduced models can thus be used to analyze the transient as well as the steady state behav...
