dc-power-flow

To calculate DC power flow with non-contiguous bus numbers, construct the susceptance matrix from branch data using bus-number mapping. This linearized approach computes line flows and loading percentages from bus angle solutions for fast grid analysis.

DC power flow analysis provides a fast, linearized view of transmission networks to support planning and operations. It reduces computational burden relative to full AC models by using small-angle approximations to quickly estimate grid responses.

Yes, you can perform contingency analysis using a linearized power flow model by computing simple sensitivity analyses. The model supports slack-bus handling to evaluate grid responses during transmission line outages for operational studies.

No, this DC power flow solution does not require complex external libraries. It operates entirely using numpy for numerical computations, constructing the susceptance matrix and calculating line loading percentages independently.

Use a DC power flow model instead of a full AC model for grid analysis when you need fast contingency screening and planning studies. The linearized small-angle approximation reduces computational burden but sacrifices AC voltage and reactive power accuracy.
