Abstract: The results concerning the integration of a set of power management strategies and serial communications for the efficient coordination of the power converters composing an experimental DC microgrid is presented. The DC microgrid operates in grid connected mode by means of an interlinking converter. The overall control is carried out by means of a centralized microgrid controller impl...

Abstract: This paper proposes a novel protection method for single line-to-ground (SLG) faults in ungrounded low-inertia microgrids. The proposed method includes microgrid interface protection and unit protection. The microgrid interface protection is based on the difference between the zero-sequence voltage angle and the zero-sequence current angle at the microgrid interconnection transformer ...

In order to integrate a proton exchange membrane type (PEM) fuel cell system (FCS) combined with a battery bank to a distribution grid; this paper proposes a local controller based on fuzzy logic. The proposed system provides primary frequency control and local bus voltage support to the local grid. This opposes the passive distributed generation of the present that do not provide auxiliary ser...

As an important part of s mart grid, microgrid(MG) is a new form of s mart grid in the future. Microgrid(MG) technology can effectively integrate the advantages of new energy and renewable energy generation and provide a novel way for large-scale applicat ions of new energy and renewable energy connecting to grid. This paper deals with the problem of economic operation of microsources in the mi...

The demonstrated research work analyses the technoeconomic modelling and sensitivity analysis of available resources for rural community in India. various used this study are solar, wind, hydro, battery utility grid-connected system. usefulness on-grid system sector is that excess amount electricity produced through renewable energy sources (RES) could be sold back to grid. A total 12 possible ...

Nowadays, governments and electricity companies are making efforts to increase the integration of renewable energy sources into grids microgrids, thus reducing carbon footprint increasing social welfare. Therefore, one purposes microgrid is distribute exploit more zero emission sources. In this work, a Stochastic Unit Commitment hybrid isolated developed. The supplies power satisfy demand respo...
