Load flow, also known as Power Flow Analysis, is an essential method to examine the problems occurring in the power systems network or grid.
Load flow Analysis is performed to determine the state of the equipment present in the network in order to ensure their operation within the specified limits. This study solves the steady operation state with node voltages and branch power flow in the power system.
There are four quantities in a system node that are classified as the Voltage Magnitude, Phase Angle, Real and Reactive Power. While defining the system nodes, we consider three types of buses.
The buses and quantities are correlated with each other. The buses are named as Load bus, Generator bus and Slack bus.
The buses with no generators are load bus (P-Q bus). Here, V and θ are unknown whereas the real and reactive power are known.
In Generator bus (P-V bus), Q and θ are unknown. At this bus the magnitude of the voltage is kept constant and the real power is provided by the prime mover of the generator.
Slack bus is also known as reference bus. The voltage is fixed in both magnitude and phase where P and Q are unknown.
To calculate load flow, there are 3 techniques out of which two are the most common.
