In this paper, we propose a two-stage transmission hardening and planning (TH&P) model that can meet the load growth demand of normal scenarios and the resilience requirements of hurricane-induced damage scenarios. To better measure the resilience re

Large-scale renewable energy integration decreases the system inertia and restricts frequency regulation. To maintain the frequency stability, allocating adequate frequency-sup-port sources poses a critical challenge to planners. In this context, we

In this paper, a novel contingency-aware method for $N-2$ security-constrained transmission expansion planning is proposed. To ensure that the transmission construction plan satisfies the $N-2$ security criterion, the proposed method takes advantage
