infinite bus is the indication that it has infinite power capacity as impedance is very less near to zero because all the generators in interconnected power system are connected parallel. can somebody elaborate on the infinite bus fundamentals.
Hello dear
The infinite bus concept is a simplifying assumption that is applied to buses or nodes with an infinite upstream fault capacity (or an equivalent upstream source impedance of zero). What this means is that the voltage at this bus or node is always constant and any downstream disturbances do not affect the voltage. Obviously, there is no such thing as an infinite bus in practice, but it is a useful approximation to make when modelling a connection to a large utility or grid network (that is, large relative to the downstream system). Such large networks are sometimes called "stiff" networks or systems.
The infinite bus is a useful concept that summarizes how most people already view the power grid. It can be applied when the power grid is sufficiently large that the action of any one user or generator will not affect the operation of the power grid.
In an infinite bus:
1. System frequency is constant, independent of power flow
2. System voltage is constant, independent of reactive power consumed or supplied
Infinite Bus is represented by a constant voltage source having zero internal impedance and infinite inertia.

A bus that is connected with a big number of synchronized generators (alternators) operating at the same voltage and frequency (phase angle and phase sequence) is called an infinite bus. This kind of bus imposes its own.
