Script with example 8.4 and function to create the impedance bus matrix of a power system from an networkx simple graph. This uses the four modification cases from Chapter 8 - “Power System Analysis” W. Stevenson et al.. The script also contains the function for Dr. Gabriel Kron’s node reduction algorithm to generate an equivalent electric power network (Chapter 7 Stevenson’s book).

Note: Input graph requires a reference node labeled -1.

• ☑ Function to create Zbus from scrath depending on edges.
• ☑ Add node index list (from input graph) that represent each row/column from Zbus.
• ☑ Function with Gabriel kron’s reduction algorithm.
• ☑ Function to reorder Zbus’s rows and columns according to input list.
• ☑ Adapt algorithm to work with MultiGraph instead of simple graph (NetworkX).
• □ Add support for coupled branches (all cases).
• ☒ Ybus creation from scratch function.
