Decentralized controls and communications for autonomous distribution networks in smart grid

A smart power distribution network configured to facilitate decentralized controls and communications for autonomous distribution networks, the smart power distribution network comprising:

• a first tier that comprises a central control center (CCC) configured to manage a plurality of distribution control centers (DCCs), each DCC representative of an autonomous distribution network (ADN);
• a second tier that comprises a plurality of first control centers (CCs), each first CC representative of a subsystem;
• a third tier that comprises a plurality of second CCs, each second CC representative of a neighborhood or a field area network;
• and
• a fourth tier that comprises a plurality of micro grids (MGs), wherein each MG comprises one or more households and each MG is managed by a second CC in the third tier, and wherein the smart power distribution, network is configured to:
• exchange of power availability and/or need information among the one or more households, the plurality of MGs, and the plurality of first and second CCs through uplink and downlink communications;
• enable collection of data from the plurality of MGs, a plurality of substations, and/or a plurality of ADNs at each tier;
• enable aggregation of the data collected from one or more of the plurality of MGs, the plurality of substations, and/or the plurality of ADNs at each tier;
• enable abstraction of the aggregated data before transmission of the abstracted data to a higher tier, wherein the abstraction of the aggregated data comprises reduction of the aggregated data into reduced data for transmission of the reduced data to a controller in the higher tier via the uplink and downlink communications, and wherein an amount of the aggregated data to be reduced is quantitatively defined by an abstraction ratio at which the information in the uplink communication is reduced;
• and
• control distribution of excess power among the plurality of MGs and a plurality of subsystems, while the abstracted data is transmitted to the higher tier.

A non-transitory computer readable storage medium with instructions stored thereon that are executable by one or more processors to facilitate decentralized controls and communications for autonomous distribution networks in a smart grid, the instructions being executable to perform or cause to be performed:

• managing operation of at least a portion of the smart grid that has been structured in a four tiered architecture, wherein:
• a first tier comprises a central control center (CCC) that manages a plurality of distribution control centers (DCCs), each DCC representative of an autonomous distribution network (ADN),
• a second tier comprises a plurality of first control centers (CCs), each first CC representative of a subsystem,
• a third tier comprises a plurality of second CCs, each second CC representative of a neighborhood or a field area network, and
• a fourth tier comprises a plurality of micro grids (MGs), each MG comprising one or more households and each MG being managed by a second CC in the third tier;
• enabling exchange of power availability and/or need information among the one or more households, the plurality of MGs, and the plurality of first and second CCs through uplink and downlink communications;
• collecting data from the plurality of MGs, a plurality of substations, and/or a plurality of ADNs sat each tier;
• aggregating the data collected from one or more of the plurality of MGs, the plurality of substations, and/or the plurality of ADNs at each tier;
• abstracting the aggregated data before transmission of the abstracted data to a higher tier, wherein abstracting the aggregated data comprises reducing the aggregated data into reduced data for transmission of the reduced data to a controller in the higher tier via the uplink and the downlink communications, wherein an amount of the aggregated data to be transmitted to the controller in the higher tier is defined by an abstraction ratio at which information in the uplink communication is reduced while power sharing among the plurality of MGs, the plurality of substations, and/or the plurality of ADNs is performed;
• and
• controlling distribution of excess power among the plurality of MGs and a plurality of subsystems, while the abstracted data is transmitted to the higher tier.
