Optimal Power Flow in Four-Wire Distribution Networks: Formulation and Benchmarking
Sander Claeys, Frederik Geth, Geert Deconinck
In recent years, several applications have been proposed in the context of distribution networks. Many of these can be formulated as an optimal power flow problem, a mathematical o…
Notes on BIM and BFM Optimal Power Flow With Parallel Lines and Total Current Limits
Frederik Geth, Bin Liu
The second-order cone relaxation of the branch flow model (BFM) and bus injection model (BIM) variants of optimal power flow are well-known to be equivalent for radial networks. In…
Load Balancing in Low-Voltage Distribution Networks via Optimizing Residential Phase Connections
Bin Liu, Frederik Geth, Nariman Mahdavi +1
Unbalance issues in low-voltage distribution networks (LVDN) can be worsened by increasing penetration of residential PV generation if unevenly distributed among three phases. To a…
