Distributed generation, coupling impedance, eigenvalues and stability
This paper intends to solve the problem of connecting distributed generations to the existing electrical system. In this paper we have processed advanced model and tools consisted in formulation of the equivalent system in order to study the dynamic behaviour of the system. The results from steady state conditions and short-circuit calculations are the basic information for the formation of the simplified dynamic equivalent. The paper is concerned with transformation of dynamic behavior of the meshed power system to the cooperation dynamic of two regulated generators working to the equivalent connection. The transformation preserves dominant dynamic features of the original system and the resulting layout enables monitoring of faults representation to the value of its equivalent connection and their impact to the function of regulations and protection equipments.
