Question

Reordering buses can be an effective sparsity technique in power flow solutions.

(a) True (b) False.

Short answer

The correct answer is (a) true.

Step-by-step solution

Definition of sparsity technique in power flow solutions.

Sparsity is used to register and cache obstruction techniques that is analogous to the concept of blocking (also referred to as tiling) used for dense matrices. However, the matter is way harder due to the matrix being diagrammatic by an indexed structure that should reorganize the organization.

Determine the correct option.

Before the Gauss elimination procedure begins, rearrange buses according to the fewest connected branches. Buses can be reordered only once, or they can be renumbered at each Gauss elimination phase to account for changes during the elimination process.

Typical bus power-flow systems use less than Megabytes of storage, less than one second of computer time per iteration, and fewer than iterations to converge due to leveraging sparsity with reordering approaches.

Therefore, the correct answer is (a) true.
