Linear AC Power Flow¶
Following the formulation presented in Linearized AC Load Flow Applied to Analysis in Electric Power Systems [1], we obtain a way to solve circuits in one shot (without iterations) and with quite positive results for a linear approximation.
Where:
Here, is the normal circuit admittance matrix and is the admittance matrix formed with only series elements of the model, this is neglecting all the shunt admittances.
Solving the vector we get for the pq and pv nodes and for the pq nodes.
