Transformer Impedance Determination for Power System Studies of Distribution Network integrated with Renewable Energy Resources

Article Preview

Abstract:

This paper presents a guideline of determining impedance of transformer when conducting system study for renewable energy interconnection. The method can be used when there is lack of information on the transformer’s technical details. Simulation examples are presented to demonstrate the effect of impedance on the losses and short circuit current. The guidelines introduce in this paper will increase reliability and accuracy of the system study conducted by engineer and researchers in assessing the possible impact renewable energy integration.
