1. An electricity distribution system comprising several microgrids and one utility company where each microgrid must be electrically connected with the utility company via a medium voltage line and each microgrid is connectable with other microgrids via a low voltage line;

  • and the utility company and microgrids are interfaced with each other via a communication network,the utility company comprising;

    a first processor configured to form a coalition of microgrids which minimize an amount of power that is exchanged between the utility company and the microgrids via the medium voltage line and which maximize an inter-microgrid amount of power that is transferred via the low voltage line upon receiving power status information, that indicates whether the microgrids requires an amount of power or whether the microgrids has a surplus amount of power, from microgrids via the communication network, anda second processor configured to produce a power transaction matrix, which is transferred via the low voltage line, based on the coalition of microgrids and that transmits the power transaction matrix to the microgrids via the communication network, whereinthe each microgrid has a load microgrid which requires power and a provider microgrid which has surplus of power,the load microgrid and the provider microgrid receive the power transaction matrix from the utility company via the communication network,the load microgrid transmits a request signal to the provider microgrid via the communication network, the request signal making a request for the amount of power that is insufficient, andthe provider microgrid transfers the power that is insufficient to the load microgrid via the low voltage line upon receiving the request signal.
