To ensure that the current-carrying capacity of lines is not exceeded
In a power-flow study, what is the purpose of creating a bus admittance matrix Ybus?
To estimate the real and reactive power flows in the system
Why is it important to iterate to find conditions that satisfy the system’s load flow equations in a power-flow study?
To update the voltage estimate for each bus based on estimates for the voltages and power flows at every other bus
What is the main target of a power-flow study in a power system?
To estimate the real and reactive power flows in the system
Why does the updated voltage in a power-flow study usually be closer to the answer than the original guess?
As a result of iterating to find conditions that satisfy the load flow equations
