What is Ybus?

Answer 1

Ybus, or the bus admittance matrix, is a key component in power system analysis, particularly for load flow studies. It represents the admittance (the inverse of impedance) of the network components connected to each bus in a power system, allowing for the calculation of currents and voltages at various points. Each element of the matrix reflects the admittance between buses, accounting for both line and transformer characteristics. Ybus is essential for analyzing the performance and stability of electrical networks.
