Corinex Introduces Groundbreaking Grid Intelligence Node to Optimize Low-Voltage Networks
In an era where electrification is placing unprecedented demands on our power infrastructure, Corinex has taken a significant step forward with the introduction of the Grid Intelligence Node (GIN). This innovative device is designed for low-voltage feeders, enabling utilities to gather near-real-time data on network conditions, thereby improving operational efficiency.
The GIN acts as a critical tool for distribution system operators (DSOs) by creating a 'grid-truth' layer. This layer allows utilities to pinpoint constraints, evaluate the available capacity, and assess the effectiveness of grid-related interventions. According to Sam Shi, Chief Technology Officer at Corinex, the GIN is instrumental in providing the necessary insight into where and when control is needed across the grid.
The Grid Intelligence Node is not only about gathering data but doing so with high precision and performance.
1. Three-phase Voltage Measurement: Achieving a root mean square (RMS) error of ≤0.5% ensures accurate voltage and current readings.
2. Comprehensive Data Metrics: The GIN measures power, power factor, frequency, and energy consumption, allowing for a fully informed operational analysis.
3. Harmonic Monitoring: It monitors harmonics up to the 51st, which is critical for understanding and mitigating electrical distortions.
4. Anomalies Detection: This includes voltage sags, swells, overloads, and phase imbalances, essential for real-time operational stability.
5. Reporting Capabilities: With operational snapshots every minute and energy aggregates every 15 minutes, GIN can even report data in one-second intervals if required.
Designed as a retrofit solution for existing infrastructure, GIN combines Corinex’s broadband powerline communications (BPL) with advanced measurement and detection functionality. This is particularly beneficial since existing low-voltage power lines can now carry both measurements and communications simultaneously.
Importantly, GIN connects directly to 230/400V networks using MQTT for data transmission, ensuring seamless integration into current systems without the need for extensive upgrading. This aspect allows utilities to enhance their visibility of network conditions without the extra expense of deploying a separate communications framework or additional revenue-grade meters at every monitoring point.
What sets the GIN apart is its ability to interface with Corinex’s Plexigrid Intelligence software. This integration facilitates a digital twin of the grid that closely mirrors real-time loading, voltage, and power quality conditions. The synergy between GIN and Plexigrid allows DSOs to refine their low-voltage state estimations and the accuracy of their grid models.
This enhanced digital representation helps utilities assess the capacity for electric vehicles, heat pumps, and photovoltaic systems, thereby allowing for better-informed decisions regarding constraints—whether they need to be managed through flexibility strategies or physical reinforcements.
As Sam Shi put it, “Digital twins are only as reliable as the information behind them.” The GIN ensures that these models are grounded in real-world measurements, aiding utilities in understanding their available capacity and making more informed decisions as the demand for electrification continues to grow.
The introduction of the Grid Intelligence Node represents a substantial leap toward smarter, more efficient utility management. Corinex’s commitment to innovation in low-voltage grid technology not only addresses current challenges faced by utilities but also paves the way for a more sustainable energy future. With the GIN now available for utility evaluations and pilot projects, it’s poised to revolutionize how we monitor and optimize our power networks.
