Autonomous community energy management system and method

An energy management system of a building divided into a plurality of zones,

• the energy management system comprising:
• a building agent that is a device managing energy of the building and is configured to receive a first incentive about a Demand Response (DR) or a Frequency Regulation (FR) from a community agent configured to manage energy of a community comprising the building, calculate a first response capacity responding to the first incentive among a building management capacity, and transmit a second incentive to a zone agent;
• and
• a plurality of zone agents, each of which is a device managing energy of a corresponding zone and is configured to, when the each of zone agents does not participate in the demand response or the frequency regulation (case 1), estimate an energy demand amount (a first energy demand amount) of the corresponding zone through machine learning (first machine learning) or calculation, when the each of zone agents participates in the demand response or the frequency regulation (case 2), estimate an energy demand amount (a second energy demand amount) of the corresponding zone through machine learning (second machine learning), determine, as a second response capacity responding to the second incentive, a difference between the first energy demand amount and the second energy demand amount, and transmit the determined second response capacity to the building agent,
• wherein the building agent is configured to receive second response capacities from the plurality of zone agents and transmit a third response capacity obtained by adding the plurality of second response capacities and the first response capacity to the community agent, and
• the second machine learning comprises, as input data, the first energy demand amount and the second incentive and calculates the second energy demand amount to maximize an objective function comprising an incentive profit obtained by the second incentive and the second response capacity and a quantified user satisfaction degree.

An energy management method of a community in which a plurality of buildings, each divided into a plurality of zones, are located,

• the energy management method comprising:
• receiving, by a community agent configured to manage energy of the community, a first incentive about a Demand Response (DR) or a Frequency Regulation (FR) from a demand management device;
• receiving, by the community agent, a first DR/FR signal corresponding to the first incentive;
• controlling, by the community agent, a first response capacity responding to the first incentive among a community management capacity in response to the first DR/FR signal;
• transmitting, by the community agent, a second incentive to a building agent;
• transmitting, by the community agent, a second DR/FR signal corresponding to the second incentive to the building agent;
• receiving, by the building agent configured to manage energy of a corresponding building, the second incentive;
• receiving, by the building agent, the second DR/FR signal;
• controlling, by the building agent, a second response capacity responding to the second incentive among a building management capacity in response to the second DR/FR signal;
• transmitting, by the building agent, a third incentive to a zone agent;
• and
• controlling, by the zone agent configured to manage energy of a corresponding zone, a third response capacity responding to the third incentive among a zone management capacity, to participate in the demand response or the frequency regulation,
• wherein the transmitting of the second DR/FR signal comprises
• transmitting, by the community agent, different second DR/FR signals to at least two building agents, respectively, according to a load characteristic for each building.
