Abstract
The exponential integration of distributed energy resources (DERs), particularly solar photovoltaic (PV) systems, into low-voltage (LV) distribution networks has introduced critical challenges regarding voltage stability. In high-impedance feeders with low $X / R$ ratios, excessive PV generation during light-load periods frequently triggers overvoltage at the Point of Common Coupling (PCC), often exceeding statutory regulation limits. To address this, this paper proposes a multi-objective control for grid-integrated PV-Battery Energy Storage Systems (BESS). Unlike conventional methods that rely on power curtailment, the proposed strategy leverages a hierarchical control architecture to dynamically manage active power flow, ensuring PCC voltage regulation while maximizing renewable energy utilization. Furthermore, a BESS sizing methodology and a technoeconomic assessment are presented to enhance the network's hosting capacity. MATLAB/Simulink results demonstrate that the proposed coordination effectively maintains voltage within prescribed limits (1.06 pu) and ensures rapid DC-link stabilization under transient conditions.
The increasing penetration of distributed photovoltaic (PV) generation in distribution networks poses significant challenges to voltage regulation, particularly during periods of high irradiance and low demand. Inverter Tripping and Dynamic Active Power Control (DAPC) have been common solutions to systems that lack an...

High photovoltaic (PV) penetration in low‐voltage (LV) radial feeders often causes midday voltage rise and upstream reverse power flow (RPF), constraining further PV integration without local flexibility. In this paper, distributed battery energy storage systems (BESS) are investigated as a practical flexibility reso...
