Modified Matpower EU PEGASE Systems

Resum

They are modified versions of the systems from the EU PEGASE project provided at Matpower database. Starting default point of these systems have been modified from their correct solution using a Gaussian distribution and a specified standard deviation. These modified cases are very interesting for validating novel Power-Flow techniques since, despite the calculated initial point is more natural than the flat start, the Newton-Raphson techniques fail for solving them when the provided starting point is used. So that, thay migth be categorized as ill-conditioned systems.
