Microgrid energy management system in a public building

Penetration of renewable energy sources, as distributed sources, and market liberalization have introduced a new concept in the power system. This globally new concept is to some extent based on the stochastic production of renewable energy sources which creates imbalance between production and consumption. One possible solution for that imbalance is a generally accepted concept of microgrids. Microgrids as an integral part of the power system, combine distributed energy sources, energy storage and load. However, in order to develop and deploy microgrids it is necessary to ensure active management of distributed sources and distribution networks. The aim of this paper is to present implementation of a microgrid in a public building by describing the concept of microgrids and offering a variety of models. Apart from indicating the possibilities and advantages of microgrids, the models identify main technical drawbacks and limitations.
