  4. Abstract:
  5. In this study, a new method is presented for transmission expansion planning in restructured power systems. In this method, the future values of maximum load demanded, bid of generators to sell power and bid of consumers to buy power are assumed uncertain. The objective of the planning problem is the minimization of the total investment cost. The constraint of the problem is satisfying two constraints with a high probability: first, the total congestion costs must be limited to a certain value and second the n-1 reliability criterion must be satisfied by the transmission network. Due to extent of the problem solution space in this study, simulated annealing algorithm is used to determine the optimal plan. In addition, a method is used to calculate the above-mentioned probability with enough accuracy by a small number of iterations. This method, with respect to the Monte-Carlo simulation method, considerably reduces the amounts of calculations. Furthermore, a number of remarks for solving the problem are employed that they reduce the solution space and strongly decrease the amount of calculations. Efficiency of the proposed method is illustrated over the IEEE-RTS power system. © 2008 Asian Network for Scientific Information
