NOVELTY - The system (100) has an analyzer which analyzes information relating to power conditions associated with multi-phase power distributed to consumer consumption nodes (CCNs) to facilitate dynamic identification of imbalance in multi-phase power in response to occurrence of imbalance, and a power controller which dynamically controls distribution of multi-phase power in portion of tier via junction node based on analysis of a subset of information relating to portion of tier, according to predefined control criterion, to control amount of imbalance in multi-phase power in portion of tier.    USE - Enhanced power system balance control system for multi-tier hierarchical EDN, e.g., smart distribution grid (SDG).    ADVANTAGE - Controls power system balance, data communications, and power distribution between respective tiers of the EDN to facilitate efficient power distribution. Facilitates management of power system balance in respective tiers of the multi-tier EDN, and provides hierarchical and de-centralized control of and communication, e.g., two-way communication, relating to distribution nodes, e.g., power distribution sources (PDSs) in the power grid in the EDN.    DETAILED DESCRIPTION - The CCNs are located in a portion of the tier in multi-tier EDN lower than other tier of the multi-tier EDN. The CCNs are associated with local power distribution system (PDS), e.g., solar power generation system, wind power generation system, geothermal power generation system, hydroelectric power generation system, diesel-type power generation system, and stored power, e.g., power stored in charged batteries of an electric or hybrid vehicle. An INDEPENDENT CLAIM is also included for a load phase balancing method for multi-tier hierarchical EDN.    DESCRIPTION OF DRAWING(S) - The drawing shows the block diagram of the system comprising a hierarchical control and communication architecture for a multi-tier EDN.
