Methods for Performing Load Flow Study
A load flow calculation is used to evaluate the state of a system for a given load and generation distribution. As the network distribution will vary noticeably during different time periods, it may be required to perform several load flow solutions pertaining to peak, light and average loading conditions.
These solutions will be used to define either optimal operating modes for normal conditions or how the system will respond to abnormal conditions.The solutions to these equations are then evaluated using iterative techniques like:
doneNewton Raphson
doneJacobian Matrix
doneGauss-Seidel method

Our Approach
We also perform Power Flow study on the latest version of ETAP. In doing this, our efficient power systems engineers builds a network of nodes interconnected by admittances (impedances). In defining nodes in a software model, we consider the following input data
BUS DATA
For PQ buses (Load Buses)
Real power (generation and demand)
Reactive power (generation and demand)
For slack bus (Swing Bus)
Voltage magnitude (usually 1 per unit)
Voltage Angle (specified to be zero)
Real power (demand),
Reactive power (demand)
For PV buses (Generator Buses):
Real power (generation and demand)
Reactive power (demand)
Voltage magnitude
