To solve the multi-objective coordinated problem of transmission networks planning, an optimal planning model is presented, in which the multi-objective function consists of the minimum investment cost, minimum operation and maintenance cost, minimum flexibility expected expense and minimum social welfare expense. The flexibility expected expense of adapting to the uncertain future is taken into account in the optimal model and is presented from the uncertain scenarios of load growth and power networks emergency. By analyzing the constraint degrees between evaluation factors of each objective function by use of the analytic hierarchy process (AHP), the judgment matrix is built to set each objective function's weight in the mathematical model. The application of the model is validated by network expansion planning on an 18-bus system.
