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.
