Abstract

The classical distribution system can evolve in a new concept of grid, where the distributed generation has a big impact. These changes take into account the use of power electronic devices. With these devices it is necessary to study the stability of the system in a new form due to their multi-current domain and the influence of the controllers applied to each device. The paper presents a methodology that takes into account the structure of a DC microgrid system and evaluates its stability. The stability analysis uses the computational continuation to obtain the conclusions. The real time simulation results present the grid behavior and validate the limits of operation.
