A generic danish distribution grid model for smart grid technology testing

摘要

This paper describes the development of a generic Danish distribution grid model for smart grid technology testing based on the Bornholm power system. The proposed approach uses a coherency based dynamic equivalent technique along with relation & participation factors, and is suitable for use with real time digital simulator (RTDS). In particular, the frequency dependent network equivalent (FDNE) method has been combined with parameter randomization in order to accurately preserve the desired properties and characteristics of the original Bornholm power system. The validity and efficiency of the proposed approach is demonstrated by comparing the transient response of the original Bornholm power system model and the developed generic model under significant fault conditions. The results clearly show that the equivalent generic distribution grid model retains the dynamic characteristics of the original system, and can be used as a generic Smart Grid benchmark model for testing purposes.
