This chapter sets forth a new approach for transmission network expansion planning that accounts for increasingly plausible deliberate outages. Malicious attacks expose the network planner, a centralized entity responsible for expansion decisions of the entire transmission network, to a new challenge: how to expand and reinforce the transmission network so that the vulnerability against intentional attacks is mitigated while meeting budgetary limits. Two vulnerability-constrained transmission expansion models are presented in this chapter. The first model allows the network planner to analyze the tradeoff between economic- and vulnerability-related issues and its impact on the expansion plans. The uncertainty associated with intentional outages is modeled through scenarios. Vulnerability is measured in terms of the system load shed. In the second model, the risk associated with the nonrandom uncertainty of deliberate outages is incorporated through the minimax weighted regret criterion. The proposed models are formulated as mixed-integer linear programs for which efficient solvers are available. Illustrative examples show the performance of both models.
