6 FAQs about [Mali smart grid topology]

How to verify grid topology using smart meter data?

To verify grid topologies using smart meter data, parameterize (R; X) from (0.3) as where a> is the `-th row of A. By slightly abusing notation, matrix A here has been augmented to include both energized and non-energized lines. Under this representation, verifying the grid topology entails nding b from grid data.
