The first part of the paper offers an overview of the state-of-art of microgrids, their architectures and the control of AC microgrid. Its second part focuses on the dynamics of the DC microgrid control taking into account an ideal and a nonlinear model of supercapacitors. It compares the transient processes obtained by simulation by using the two different supercapacitor models.
The paper is concerned with the study of a DC microgrid supplied among others from biogas mini power plant and from renewable energy sources and loaded by telecommunication and data center consumers. The microgrid is operated in stand alone mode in remote places. For continuous and reliable power supply energy storage units are applied. The operation of the microgrid and the load leveling and sharing...
