Decentralized controls and communications for autonomous distribution networks in smart grid

Abstract

Technologies are generally described for addressing the bidirectional power flow conflict incurred by power surpluses produced from a number of households' on-location energy generation units (e.g., solar) in power distribution networks. A micro grid composed of households in a neighborhood may be considered as a generating- or consuming-resource entity at different time periods. The approach may be formulated as a power balance computation such that power balance may not be achieved within the micro grid itself, and therefore power sharing (or redispatching) among micro grids is operated, before requesting power from the macro grid, i.e., the fuel-based conventional grid. Enhancement of renewable energy utilization and reduction in the amount of data packet traffic in exchange of information and control messages via uplink and downlink transmissions throughout an overlay multi-tier communications network infrastructure may be taken into consideration in example implementations.
