Next-Generation Smart Inverters for Stable and Secure Solar Energy Grid Integration

energyPilotedTRL 7

Imagine the power grid as a giant spinning wheel that keeps electricity steady; as we switch to solar, we lose that heavy wheel and the grid becomes shaky. This project builds a smarter 'electronic brain' for solar panels that mimics that stability and prevents blackouts. It also adds a health-check system to tell you when parts are wearing out before they actually break.

The business problem

What needed solving

The shift to solar energy has removed the natural stability (inertia) of power grids, increasing the risk of blackouts. Additionally, current inverters often lack the interoperability and health monitoring needed to prevent costly downtime.

The solution

What was built

A 100 kW bidirectional inverter and SiC-based topologies for ≥2 kV operation, paired with a cybersecurity platform and health monitoring system.

Who can put this to work

Utility-Scale Solar
enterprise
Target: Solar farm operators

If you are a solar farm operator dealing with energy curtailment and grid instability — this project developed SiC-based inverter topologies that enable operation at ≥2 kV. This allows for direct MV connection, reducing energy losses and increasing overall yield.

Electrical Distribution
enterprise
Target: Distribution System Operators (DSOs)

If you are a DSO dealing with the risk of blackouts due to low system inertia — this project developed control algorithms providing synthetic inertia and dynamic current injection. This reduces the need for costly grid reinforcements and improves resilience.

Power Electronics Manufacturing
mid-size
Target: Inverter manufacturers

If you are an inverter manufacturer dealing with high failure rates and maintenance costs — this project developed integrated condition and health monitoring. This enables predictive maintenance and extends the lifetime of the hardware.
