New SynGRID paper published in IEEE Access

A new research article supported by SynGRID has been published in IEEE Access: “Co-Simulation-Based Evaluation of Control Mechanisms for Active Low-Voltage Network Scheduling,” authored by Marina Dubravac, Danijel Topić and Goran Knežević (FERIT Osijek) and Tomislav Antić (University of Zagreb Faculty of Electrical Engineering and Computing).

The paper presents a co-simulation model, combining power flow analysis with particle swarm optimisation, to evaluate four control mechanisms available in active low-voltage networks, transformer tap changer, PV active power curtailment, PV reactive power control and EV charging curtailment, against three objectives: minimising voltage deviation, energy losses and voltage unbalance.

Tested on a real-world low-voltage feeder across 45 case studies, the proposed control reduced daily energy losses from 164.98 kWh to 6.09–14.33 kWh, kept voltages within a 0.92–1.09 p.u. band and lowered the voltage unbalance factor from 2.41% to 0.46–1.52%. The results show that active power curtailment is decisive in low-voltage networks, while reactive power control alone is insufficient under existing regulatory limits. From the operator’s perspective, losses minimisation emerged as the most suitable single objective.
