Microgrid supply management

Microgrids represent a means of improving the conventional electrical grid network, making it more reliable, secure, cooperative, efficient and, especially cleaner. This paper presents the management of a hierarchical DC-coupled microgrid with distributed architecture implemented in a microgrid laboratory containing two renewable sources, namely wind and hydro. Power supply management strategies are applied in order to supply a critical, non-dispatchable load. Due to effective management, the microgrid is robust and capable of handling most of the problems that are associated with renewable energies.
