Energies, Vol. 12, Pages 3216: Load Flow Independent Method for Estimating Neutral Voltage in Three-Phase Power Systems (Energies)

A precise modeling of three-phase power systems is of great importance due to its abilityto represent load unbalance and asymmetry in system components. A further enhancement in powersystem modeling is the computation of neutral voltages, which has been frequently neglected inearlier works. In this Letter, a novel approximate method is proposed for estimating neutral voltages.The method has as its main advantage not requiring the use of load flow algorithms with explicitneutral conductor modeling, thus being applicable to available load flow results in which the neutralvoltage was originally omitted.
