Grid-Code Compliance

Every generator must meet a grid code governing ride-through, reactive support, and protection; the burner meets it through its power-electronics interface.

The rules of connection

A grid code is the set of technical requirements a generator must meet to connect and operate: staying online through voltage and frequency disturbances (ride-through), supplying or absorbing reactive power for voltage control, limiting harmonics, and coordinating protection so faults are cleared cleanly. Compliance is mandatory and tested before commissioning.

The burner (MetroVolt) interfaces through inverters, so much of its grid-code behaviour is set in the power-electronics control rather than in machine physics. Modern grid-forming and grid-following inverter controls can meet ride-through, reactive-power, and harmonic requirements, which is the basis for MetroVolt's compliance design.

An advantage and a responsibility

The power-electronics interface gives fine control over grid-code behaviour, and can provide services a synchronous machine cannot, such as fast, programmable reactive support. But inverter-based resources must be designed carefully to provide adequate fault current and stable behaviour on weak grids, which is an active engineering area.

Honest framing

Grid-code compliance is a design and testing task that applies once the unit exists. MetroVolt's inverter design is at the concept stage; compliance is a target of the engineering program, verified only on built hardware.
