Integration of New Players in the Low-Voltage Grid: Distributed Generation, Electric Vehicles, and Heat Pumps

The energy transition is transforming the electrical system into a more decentralized, dynamic, and bidirectional network. In this new context, the low-voltage (LV) grid becomes a key connection point for new players such as distributed generation (especially photovoltaic), electric vehicle (EV) charging infrastructure, and HVAC systems.

While these additions are essential to progress toward a more sustainable energy model, they also pose significant technical challenges for distribution companies and grid operators.

Technical Challenges in the LV Grid with the Emergence of New Players

La creciente presencia de generación distribuida y grandes cargas flexibles en la red de baja tensión puede generar diversos problemas operativos si no se despliegan de manera adecuada:

The growing presence of distributed generation and large flexible loads in the low-voltage network can lead to various operational issues if not properly deployed:

Line Overloads and Voltage Fluctuations
The increased demand from electric vehicle charging and other high-consumption systems such as climate control or heat pumps can overload local distribution lines. Likewise, energy injection from photovoltaic installations can affect network voltage and lead to overvoltage issues.

Phase Imbalance
Asymmetric phase connection of generating installations and large loads can cause energy losses, equipment stress, and even unnecessary tripping of protection systems.

Power Quality Issues
The proliferation of power electronics (inverters, rectifiers, etc.) introduces harmonics, overvoltages, and other phenomena that can affect grid stability and the proper functioning of connected equipment.

How Pronutec’s Smart Grid Solutions Help

At Pronutec, we address these challenges by providing real-time visibility of the LV grid. Our Smart Grid solutions, such as smart fuse switches (SFS) and the new Live Retrofit Supervisor (LRS), offer:

Real-Time Measurements
Monitoring of voltage, line and phase current, active and reactive power (imported and exported), as well as power factor, waveform quality, and frequency.

Compatibility with Any Infrastructure
Possibility to install in existing panels, even older ones, without the need to interrupt the supply or modifying existing infrastructure.

Integration with Analytics Platforms
Open architecture allows monitoring data to be easily and simultaneously integrated into management and analytics platforms using communication protocols such as Web Services, Modbus TCP, IEC 60870-104, DNP3, or MQTT.

Quick and Non-Intrusive Installation
Thanks to its modular design and optimized wiring, installation is fast, safe, and well-organized.

From Passive to Smart Grid

The integration of distributed generation and electric vehicles is not just a challenge—it’s an opportunity to modernize, digitalize, and optimize the low-voltage network. With our monitoring solutions, we help transform the grid into a smarter infrastructure, ready to face the challenges of the future energy landscape.
