N2 - This paper proposes an optimal hardening strategy for improving the distribution system resilience against any approaching wildfire. In this paper, three hardening strategies are taken into account, namely: 1. Vegetation management 2. Pole upgrading 3. Undergrounding overhead distribution branches. Subsequently, the optimal strategies are determined based on the available resources. The problem is expressed in terms of a mixed integer linear programming (MILP) optimization problem. A modified wildfire model is employed to simulate the impacts of approaching wildfire, on overhead distribution lines. In addition, the effects of different vegetation types on the progression of wildfire toward nearby distribution lines and subsequently the rise of those lines conductors' temperature are analyzed through the presented framework. The modified IEEE 15-bus distribution test system is studied by this framework to demonstrate its effectiveness.
