Abstract


Power electronic interfaces (PEI) play an important role in future power systems. From planning and operation perspectives,
there is a need to model PEIs for power flow applications. In this paper, precise modeling of a DC-DC boost converter
for load flow analysis is presented, which can be generalized for other kinds of PEIs. As an application, the presented
model is employed for uncertainty analysis of systems, considering uncertainty in wind power generation. The simulations
are performed on a wind farm DC distribution network. The results demonstrate the robustness of the presented load flow
algorithm.
