Germany
German TSO Amprion embarked on a coordinated reactive power exchange with Germany’s biggest DSO E.ON. The aim of the practice is to make a joint contribution to the fundamental transformation of the energy system by quickly and cost-effectively improving voltage stability in the transmission grid.
Highlights
01
Creates independence from conventional energy sources while maintaining security of supply.
02
Expands capacity of power system to incorporate renewables.
03
Accelerates the energy transition by reducing the need for new generation plants as the TSO can use previously unused potential from the distribution grid instead of constructing new assets.
04
Represents a solution that can be extended to almost all electrical grids worldwide.
Main Information
As part of the energy transition, conventional power plants (coal, nuclear and gas) are being decommissioned, making the influence of variable renewable energy on the electricity grid increasingly important. In this context, new reactive power compensation systems must be built to ensure that voltage limits continue to be maintained.
Compensation systems that utilse the reactive power potential of wind turbines are already in place for voltage control in the distribution grid, but do not extend to the transmission grid. To change this, Amprion and E.ON developed a concept for a coordinated reactive power exchange between the transmission and the distribution grid in real-time operation that exploits synergies in voltage control. The concept has since been successfully tested in the field and is now used in daily operations.
