A Two‐Stage Approach for Reducing Unbalance and Voltage Deviation Along With Active Power Losses in Active Distribution Networks Considering Load Pattern

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This paper proposes a two‐stage optimisation approach for the optimal operation of equipment in an active distribution network (ADN), considering the load pattern. In Stage I, system uncertainties are modelled using Latin Hypercube Sampling (LHS), and correlated uncertainties in DERs (e.g., wind turbines [WTs] and photovoltaic [PV]) are addressed via ...
