Information
This model represents an AC current distribution system, whose complexity depends on two parameters N and M.
A constant voltage source is connected to a primary resistive distribution line which is split into N segments, each with an impedance R_d1 + j*beta*R_d1. At the end of each segment, a secondary distribution line is attached with M elements each of impedance R_d2 + j*beta*R_d2. At the end of each secondary segment, a linear load connected, which is internally grounded on the other side.
Each load measures its absorbed active power and adapts its internal resistance to match the required active power set point.
