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 ...

Integration of Distributed Energy Resources in Low Voltage Distribution Networks—Croatian Regulatory Perspective

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
Graphical abstract shows the difference between the concepts investigated in the manuscript. It emphasizes the shortcomings and advantages for each of them. Also, it addresses some of the changes in LV networks that are the main reason DSOs need to change the current practice in the assessment of new connection requests.
