Grid feed-in at high-voltage level: a case study
Grid integration is a key issue in the expansion of renewable energies throughout Europe. The requirements for power generation plants at all voltage levels have changed significantly with the pan-European harmonisation of grid connection requirements and the resulting adaptations to the national foundations. The aim of the EU regulation is to create a stable electricity grid throughout Europe in order to further increase the share of renewable energies with respect to climate goals. ‘We are glad to have found a competent and very experienced partner for power plant control in meteocontrol.’ These new regulations close the gap, particularly in the area of verification, which previously presented a grey area at the project level: manufacturers attested themselves with a manufacturer’s declaration that ensured that their power plant controllers fulfilled the necessary requirements. Project-specific uncertainties during commissioning were the result. With the new network code throughout Europe a new step has been made. Creating a solar power plant in the three-digit megawatt range such as Midden-Groningen with feed-in at the high voltage level is a challenge that is unparalleled in its complexity and scope. The requirements for power plant control, especially for voltage and reactive power control, were high and the verification process
