Principles of power management in a smart microgrid based on Std. IEC 61850

Abstract

In recent years, the structure of the electrical power system has changed, and all aspects of power generation have shifted towards bidirectional and smart methodology. The Microgrid (MG) as a popular concept for the modern grid and advanced communication techniques play major role in future smart grids. In this regard, this paper presents the principles of MG power management from communication point of view. Moreover, there have been recent efforts to standardize MGs, and it is in terms of these advances that the current paper present the investigation based on IEC 61850 standards. Finally, the hierarchical levels of both the power and communications sides are discussed, and the responsibility of each level is summarized based on the standards.
