POWER FLOW
load flow
POWER FLOW• Important for
• Planning• economic • Scheduling• control of an existing system• planning its future expansion
• The objective is• determining the magnitudes and phase angle of voltages at each bus• active and reactive power flow in each line
• Type of buses• Slack busOne bus, known as slack or swing bus, is taken as reference where the magnitude and phase angle of the voltage are specified. This bus makes up the difference between the scheduled loads and generated power that are caused by the losses in the network• Load buses - P-Q buses• generator buses - voltage-controlled buses - P-V buses
