Impact of Distributed Generation on Performance of Power Flow Methods

Abstract

Distribution network power flow (DNPF) is a core application of distribution management system (DMS). Two methods to implement fast DNPF are using Newton-Raphson (NR) approach and current iteration (CI) approach. In distribution systems with high penetration of renewable energy sources both methods must be able to model PV nodes correctly and efficiently. This paper explores implementations of NR DNPF and CI DNPF, their execution time and performance in networks with numerous distributed generators.
