SATEC Solutions for Renewable Energy Management

Dynamic Containment with the PRO Series and PM180 Meters

The integration of renewable energy sources introduces variability to the grid, presenting frequency stability as a major challenge. SATEC's PRO Series and PM180 meters deliver precise frequency readings with a resolution of 0.001 Hz or better, and support data transfer over ModBus every 10ms for rapid response capabilities. With configurable setpoints, these meters can instantly activate relay operations, enabling swift reaction to grid frequency fluctuations.

For post-event analysis, SATEC RTR software records frequency and other critical parameters every 50ms into a CSV file, providing comprehensive data insights for Dynamic Containment strategies. By actively balancing supply and demand, SATEC's metering solutions play a vital role in preventing frequency deviations, maintaining grid stability, and helping utilities adhere to regulatory requirements.

G99 Compliance for Renewable Energy Integration

Compliance with grid connection standards, such as G99 in the UK, is crucial for renewable energy providers to safely connect to the main grid.

SATEC's Class A Power Quality Analysers meet G99 C.6 requirements, providing essential Dynamic System Monitoring, Fault Recording, and Power Quality Monitoring to ensure that energy exported from renewable sources does not disrupt grid stability.

G100 Solutions for Import/Export Limitation Scheme

Renewable energy sources, particularly solar PV systems, can often produce power levels that exceed what the local grid can manage. SATEC offers G100-compliant solutions, utilising PRO Series meters with embedded logic controllers, digital inputs, and relay outputs.

With SATEC's G100 solution, operators can implement reliable import/export controls that automatically adjust power output based on pre-agreed import/export limits, maintaining grid stability and avoiding penalties.

Failsafe Overload and Reverse Power Protection

Overload and reverse power flow are significant concerns in renewable energy applications, where energy can flow in both directions. Failsafe overload and reverse power protection systems are essential for supporting G100 solutions in high-voltage applications, and in many cases, they can serve as a simpler alternative. By precisely monitoring load levels and detecting reverse power conditions, SATEC meters help operators manage renewable energy assets safely, preventing power surges and protecting valuable equipment.

Advanced DC Metering for Renewable Energy Systems

Many renewable energy systems, such as solar and battery storage, operate on direct current (DC). SATEC's DC metering solutions, featuring Ultra High Accuracy Current Sensors (UHACS) in the PRO Series, provide precise measurements of DC voltage, current, and power. This high-precision DC metering allows operators to monitor and optimise the performance of renewable energy sources and storage systems, ensuring efficient power generation and energy management.

SATEC DC meters meet regulatory requirements and can be used for the measurement and recording of electricity transfers at Asset Points for settlement purposes.

Applications of SATEC Meters in Renewable Energy Systems

SATEC's metering solutions are ideal for a wide range of renewable power applications:

• Solar PV Systems
  SATEC meters facilitate efficient solar energy production management with features such as export limitation (G100 compliance), real-time DC metering, reverse power protection, and G99 monitoring. Our solutions ensure that solar power is seamlessly integrated into the grid, meeting all regulatory standards.
• Wind Power
  SATEC meters support wind energy providers with reliable monitoring as part of plant automation systems, ensuring grid frequency stability and managing fluctuations in wind power generation. Our meters' ability to monitor voltage, current, and frequency in real-time promotes optimal grid stability.
• Battery Energy Storage Systems (BESS)
  In battery storage applications, accurate DC metering is essential for tracking charge and discharge cycles. SATEC meters provide the real-time data required to optimise storage systems, manage energy flow, and integrate stored power with the grid.
• Micro-Grids and Hybrid Renewable Systems
  SATEC meters are ideal for micro-grids and hybrid systems that combine multiple energy sources. With overload and reverse power protection, our solutions meet the complex requirements of micro-grids, ensuring stable operation and efficient use of renewable energy.
