Research on OPF Control of Three‐Phase Four‐Wire Low‐Voltage Distribution Network considering Uncertainty

International Transactions on Electrical Energy Systems, Volume 2024, Issue 1, 2024.
As power systems become more complex and uncertain, low‐voltage distribution networks face numerous challenges, including three‐phase imbalances caused by asymmetrical loads and distributed energy resources. We propose a robust stochastic optimization (RSO)‐based optimal power flow (OPF) control method for three‐phase four‐wire low‐voltage distribution
