Power management for collaborative microgrids

Microgrids integrating green energy receive more attention from consumers since they present significant benefits including the ability to rely on more localized sources of power generation and keeping the environment healthy and safe. Thus, neighborhoods/cities opt for providing energy from green resources. However, the integration of renewable energies could lead to certain problems such as the destabilization and destruction of the power grids. For this reason, it is essential to build a robust management system and efficient communication between microgrids devices. This paper proposes a new approach based on a dynamic assignment of renewable energy tokens (DARET) algorithm and investigates a non-uniform hierarchical modulation as a data transmission technique over wireless channels. The proposed algorithm allows residential microgrids of a small geographic area to dynamically collaborate and share their individual green energy generation in order to supply their overall loads. The sharing is dynamically updated in short-term by exchanging data, in terms of individual demands and supplies, between the consumers over wireless links.
