15 Questions
What is the main objective of a power-flow study in a power system?
To analyze the power system performance under steady-state conditions
What is the initial step in finding the power-flow solution via iteration?
Creating a bus admittance matrix Ybus for the power system
Why does the updated voltage estimate for each bus in the power system not usually be correct?
Because the voltage at a given bus depends on the voltages at all of the other busses in the system, which are just estimates
What does a power-flow study target on determining under specified generation and load conditions?
Voltages, currents, and real and reactive power flows in a system
What is the purpose of iterating to find conditions that satisfy the system’s load flow equations?
To update the voltage estimate for each bus based on the estimates for the voltages and power flows at every other bus and the values of the bus admittance matrix
