Small-signal stability analysis of dc microgrids considering electric vehicles

Alejandro Garcés-Ruiz

Abstract


This paper presents a generalized model for small signal stability in DC microgrids considering electric vehicles. The proposed model considers four types of terminals, namely: constant power, constant voltage, constant current and constant impedance. A Newton-Raphson methodology is used to calculate the operation point of the microgrid and a sensitivity analysis is also presented. Some general features of the DC microgrid based on the intrinsic characteristics of the model are presented. Simulation results on different type of microgrids show the proposed small signal model is accurate compared to dynamical simulations.


Keywords
