4 Harmonic Load Flow Analysis for Radial Distribution Systems

DOI: 10.1201/9781003369448-4

4.1 Introduction

A load flow analysis involves finding all of the node voltages. After that it is possible to compute currents, power flows, system losses, and other steady-state quantities under given load conditions. These analyses are essential for the continuous evaluation of the existing power system and effective planning of alternatives for system expansion to meet increased load demand in the future. Load flow studies are helpful to confirm selected transformer, capacitor banks, and cable sizing. These studies should also be used to confirm the adequate voltage profiles during different operating conditions, such as heavily loaded and lightly ...
