Smart-grids are advanced power systems that have capability to control the power loading by
saving the purchasing cost of extra electricity and alleviating power losses. The communication
between the micro station (MS) and Micro-grid (MGs) is a key issue in smart grid where its
performance affected by transmission pricing and extra exchanged power pricing that considers an
efficient role on the pricing stability of the smart micro-grids. Therefore, interchange mechanism is
proposed in (MGs) to integration, fulfilment of all requirements and enhanced routing of
communication in smart-grids. We study the power consumption and the load-price mapping for
coalitions with lower repetition time and equal contribution to fulfil all requirements. This achieved
by means of optimization problem that increment of total revenue, which based on the optimization
tool function. We used Coalition Game Theoretical Formulation Strategy (CG-TFS) to meet the
high-speed routing of smart grid requirements and additional profits (ie, payoff) resulting from
coalitions will be distributed by their equal participation role" Equal Sharing Role "to find optimal
coalitions using the Pareto Order for power Transmission.
