Low-voltage networks are becoming increasingly complex, driven by the rapid integration of distributed energy resources (DER), electric vehicles (EVs), and photovoltaic systems (PV). For distribution system operators (DSOs), this creates a growing need for greater grid visibility, improved power quality monitoring and more precise operational control.
At the CIRED 2026 Brussels Workshop, Smilics Technologies will present a technical paper based on a large- scale field deployment in Bucharest, developed in collaboration with Retele Electrice Romania, a DSO within the PPC Group, and with the support of our local partner Eneroptim. Such partnerships are essential to bridge the gap between technology development and real-world grid implementation.
Accepted paper titled: “Digital Low-Voltage Monitoring Deployment in Bucharest, Romania: Lessons Learned from a Large-Scale Field Implementation” will be presented at the CIRED 2026 Brussels Workshop:
📆 Date: 9 June 2026
🕒 Time: 14:55
Attendees will have the opportunity to discuss the deployment, challenges, and key findings directly with the team.
From Limited Visibility to Data-Driven Grid Management
The work presented in the paper explores how real-time LV monitoring enables a shift toward more informed and proactive grid management, addressing key operational challenges in evolving LV networks.
In many cases, DSOs still rely on limited data at transformer level, making it difficult to:
- Accurately understand load distribution across feeders.
- Detect imbalances or abnormal conditions early.
- Maintain consistent power quality.
- Respond proactively to changing grid conditions.
As a result, operational decisions are often based on partial or delayed information. By enabling continuous access to granular, feeder-level data, DSOs can significantly improve: Grid visibility, power quality assessment and operational decision-making. This transition from aggregated data to real-time insight is key to managing increasingly dynamic LV networks.
Key Learnings from the Bucharest Deployment
Based on a large-scale field implementation, the paper highlights several important insights:
- Scalable deployment is essential for effective LV monitoring.
- Standardization simplifies installation across substations.
- Continuous data access improves network understanding.
- Flexible system design is required to adapt to real conditions.
These learnings are directly relevant for DSOs facing similar challenges across modern distribution networks.
About CIRED
CIRED (International Conference and Exhibition on Electricity Distribution) is a key forum where utilities, DSOs, researchers, and technology providers share practical insights and field experience.
The 2026 Brussels Workshop focuses on major challenges in electricity distribution, including Integration of distributed energy resources, increasing electrification, digitalization of grid infrastructure & Improving operational visibility and control.
The acceptance of this work at CIRED 2026 reflects the growing importance of real-time LV visibility in enabling more informed and proactive grid management. As low-voltage networks become more dynamic, scalable and data-driven monitoring is no longer optional.
Developed in collaboration with Retele Electrice Romania and Eneroptim, this deployment demonstrates how field- proven solutions can support DSOs in managing increasingly complex distribution networks, while reinforcing Smilics Technologies’ commitment to advancing grid digitalization through practical, real-world implementations, as a trusted energy partner.
We look forward to continuing the conversation at CIRED 2026 in Brussels.
