Summary form only given. This paper presents an optimum power flow (OPF) modeling algorithm that uses the primal-dual interior point technique to determine the best investment strategy in the transmission line expansion problem. In the proposed method the expansion decision (0 or 1) is mitigated by using a sigmoid function which is incorporated in the OPF problem through the modified DC power flow equations. The investment decision is taken using a new heuristic model based on enhanced… CONTINUE READING
