Abstract

In this paper, a new power flow algorithm for distribution with DER is proposed, in which a flexible modeling method is adopted. The DERs and radial system are modeled as 3-sequence components and 3-phase component respectively. Then, using Jacobian-Free Newton-GMRES(m) method, a decomposition and coordination algorithm is forged to obtain the overall network power flow, The IEEE 13 bus system is used for case studies. By comparing with the time domain solution using the PSCAD/EMTD, the proposed algorithm is tested throughly, which validates its flexibility and accuracy.
