Abstract
The increasing installation of distributed energy resources (DERs) by end consumers introduces new operational challenges to distribution networks. Although several studies investigate these impacts, most proposed control strategies are implemented independently, focusing on individual elements such as substation voltage adjustment, network reconfiguration, or inverter-based DER controls. These approaches often overlook both the interactions among different control mechanisms and the interests of end consumers, concentrating primarily on the system operator’s perspective. As a result, their potential to achieve more balanced and effective solutions is limited. This paper proposes a coordinated multi-objective optimization approach that integrates substation voltage adjustment, network reconfiguration, and the determination of Volt-Var and Volt-Watt control setpoints. By combining these strategies, the search space is expanded, enabling the identification of superior solutions that better balance the competing objectives of minimizing power losses, increasing DER hosting capacity, and maximizing the active power supplied by DERs. The multi-objective optimization problem is formulated with these three objective functions and a set of operational constraints, explicitly considering the interests and requirements of both end consumers and system operators. Furthermore, uncertainties related to load demand and DER generation are addressed using a Monte Carlo method. The proposed methodology is applied to the IEEE 69-bus distribution system and the optimization problem is solved using the Multi-objective Cuckoo Search Algorithm. The results demonstrate that the coordinated strategy outperforms isolated approaches by completely eliminating violations and reducing losses by 47.60%, while incurring only a 7.27% reduction in active power injection from DERs.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
