【 摘 要 】

Identifying backbone grid has great significance to the differential planning of power grid, which can improve the ability to withstand natural disasters effectively. In this paper, the problem of exploring backbone grid is formulated as a mixed integer nonlinear programming problem and the optimization target should balance the survivability and cost. Then, the problem of searching for backbone grid is solved with improved biogeography-based optimization algorithm, and several improvement strategies are employed to enhance the convergence rate and precision of the proposed method. The simulation verifies that the mathematical model can identify backbone grid appropriately and the improved algorithm can figure out backbone grid more effectively.
