This paper proposes a method for choosing the best coordinated expansion planning of generation and transmission systems considering an annual outage cost and a probabilistic power system reliability criterion (RLOLEGTS). The objective method minimizes a total cost which are not only an investment budget for constructing new generators and transmission lines but also an annual outage cost. Main...

In this paper, system planning network is formulated with mixed-integer programming. Two meta-heuristic procedures are considered for this problem. The cost function of this problem consists of the capital investment cost in discrete form, the cost of transmission losses and the power generation costs. The DC load flow equations for the network are embedded in the constraints of the mathematica...

Transmission expansion planning with re-design has been recently proposed in the literature to improve on the classical transmission expansion planning by allowing to cut-off circuits while expanding the network. Although the reductions in the solution costs are significant, the resulting mixed-integer linear programming formulations are very difficult to solve exactly for large networks. In th...
