This paper proposes a new comprehensive integrated planning strategy for the resilience enhancement of power system, including determining the transmission expansion and sectionalizing-based optimal black start (BS) resources allocation of battery energy storage system (BESS) during extreme events.The planning model comprises of two stages, namely the normal stage and resilience stage.The first stage is to make the collaborative planning decisions, i.e., constructing transmission lines and installation of BESS as BS sources.The second stage minimizes the power system generation cost and load shedding cost under disaster conditions.The planning algorithm is developed to describe the uncertainty of transmission lines outage status, which can be affected by the normal stage expansion states.In algorithm ways, the model was solved with a duality-based column and constraint generation (D-CCG) method.Taking IEEE 30-bus and 39-bus system for examples and GUROBI/CPLEX was utilized to solve proposed model.Numerical cases show the effectiveness of the model and the superiority of the solution strategy.
