Load flow, also known as power flow, is a steady-state analysis of power system network1234. It determines the operating state of the system for a given loading2. The power flow model of a power system is built using the relevant network, load, and generation data1. The flow of active and reactive power is called power flow or load flow, and it affects the voltages of buses and their phase angles5. Outputs of the power flow model include voltages at different buses, line flows in the network, and system losses1.
