Application of zero-reflection controllers on two-dimensional power systems

This paper introduces the application of a zero-reflection controller (ZRC); designed for the two-dimensional large electric power systems. The controller is designed to oppose the effects of power system electromechanical wave propagation that follow disturbances occurring at any point in the mentioned power system. The continuum principle, which considered for the proposed power system leads to a set of nonlinear partial differential equations (PDE). So, the discretization concept was applied in this paper. Analysis of ZRC effects is performed for different system cases. MATLAB package is used to carry out the simulation. Simulation results in different situations are presented and discussed. These results present and show the important effects of ZRCs in two-dimensional power system electromechanical wave propagation mitigation.
