Berlin - Last week’s stormy conditions in the 50Hertz grid area led to a very high feed-in of wind-generated electricity. On the evening of Sunday, 22 February, a new record was made: never before could so much wind power be taken up by our system and never before did so few wind turbines need to be curtailed.
50Hertz System Management established this new record for the integration of wind power into the grid and system between 6.30 pm and 6.45 pm. During this time, a wind power feed-in of 16,270 megawatts was registered in the 50Hertz grid area. At the same time, only 460 megawatts (and therefore a very small percentage of the wind power) had to be curtailed. The greater part of the wind power that was generated, was transported from north to south and almost completely used. The previous record was made on 4 March 2019, when 16,217 MW of wind power flowed into the grid, but about 1,300 MW of wind power still needed to be curtailed.
Dr Dirk Biermann, Chief Markets and System Operations Officer at 50Hertz: ‘This exceptionally good ratio between feed-in and curtailment shows that the measures we have taken to increase the capacity and optimise our grid are having a positive effect. What’s more, the operators of conventional lignite- and coal-fired power plants can in the meantime operate their installations with much greater flexibility, so that their output can be lowered when the wind is strong, thus making room for wind power from the northeast.’
