For the purpose of evaluating the busbar voltage dip in the grid and guiding the planning, operation and reconstruction of the grid, and in consideration of various types of busbar faults and different grid operation modes, this paper establishes the evaluation indices for busbar voltage dip in the grid and defines the busbar criticality index and busbar vulnerability index from two perspectives: the influence of busbar fault, and the frequency of voltage dips caused by the fault of other busbars. The indices are employed to identify the critical and vulnerable busbars in the grid, and to evaluate the grid operation mode and grid planning/reconstruction plans, providing guidance to the planning, reconstruction and operation optimization of the grid. Finally, the feasibility of the proposed indices is proved by an example.
