DNV Subsidiary launches solution for stabilizing power networks

GreenPowerMonitor, DNV’s integrated solution provider for the management and maintenance of renewable power installations, today launches the world’s most advanced solution to guard against power fluctuations in electricity grids.

GPM Power Oscillation Damping (GPM POD) reduces oscillation and makes power transfer more stable, while reducing additional costs and supporting grid operators to meet regulations that ensure our power networks are ready to underpin the clean-energy transition.

Increased renewable generation and large, complex power networks means that different parts of the grid are not always perfectly synchronized, which can cause the power to fluctuate. To guard against fluctuations in power supply, traditional power grids have synchronous generators which can help mitigate oscillations due to their inertia. However, with the increasing penetration of inverter-dominated renewable power plants, the power grids inertia is decreasing. This can reduce the quality of the power and makes the network susceptible to power cuts.

Unlike conventional inverter POD control, the GPM POD functionality uses the power plants centralized control to perform the control directly, eliminating the need for extra equipment, which saves money for grid operators, which can stretch to hundreds of thousands of euros.
