Abstract Although regular curtailment of wind power has not been necessary in the Nordic power system so far, rapidly increasing wind power capacity means that it may be needed in the future. To estimate the amount of curtailment in the future Nordic power system we develop an hourly dispatch model based on open data. The model is validated against historical data and used to perform a case study for the Nordic power system in 2025 to estimate the amount of wind power curtailment under different assumptions. Curtailment is found to be below 0.3% of available generation for a 26 GW wind scenario and below 1.7% for a 33 GW wind scenario, when considering trade with neighbouring systems. The most important measures for decreasing curtailment are found to be increased transmission capacity, particularly between the areas in Sweden and those in Norway and Denmark, as well as flexibility of nuclear generation. Inertia requirements are found to have a limited impact on curtailments.

考虑传输容量、惯性限制和发电灵活性的北欧电力系统限电分析

摘要 虽然目前北欧电力系统还没有必要定期限电,但风电容量的快速增长意味着未来可能需要。为了估计未来北欧电力系统的限电量,我们基于开放数据开发了每小时调度模型。该模型根据历史数据进行了验证,并用于对 2025 年北欧电力系统进行案例研究,以估计不同假设下的风电限电量。在考虑与邻近系统的贸易时,发现弃风量低于 26 GW 风电情景的可用发电量的 0.3%,而对于 33 GW 风电情景则低于 1.7%。发现减少限电的最重要措施是增加输电容量,特别是在瑞典与挪威和丹麦的地区之间,以及核能发电的灵活性。发现惯性要求对限电的影响有限。
