Abstract

Particularly on the hour, significant grid frequency deviations can be observed in continental Europe. These deviations are deterministic and caused by large power imbalances. The latter are mainly caused by the difference between the continuous load and the stepwise changes in power plant schedules resulting from electricity trading based on hourly products. Deterministic frequency deviations are undesirable, because they lead to significant activation of balancing reserves. Therefore, several remedial actions have been implemented in order to mitigate the deterministic frequency behavior, such as the introduction of ¼-h-products in intraday markets, tighter regulation for balance responsible parties, and harmonization of EU guidelines. In this paper, the effectiveness of these actions is analyzed and the development of the frequency behavior since their implementation is evaluated. Moreover, current trends and underlying causes are presented, together with further possible measures that may be required in the future.

欧洲当前市场发展对确定性电网频率偏差和频率恢复储备需求的影响

特别是在整点时段，可以在欧洲大陆观察到明显的电网频率偏差。这些偏差是确定的，是由巨大的权力不平衡造成的。后者主要是由于基于小时产品的电力交易导致连续负荷与电厂计划逐步变化之间的差异造成的。确定性频率偏差是不可取的，因为它们会导致平衡储备的显著激活。因此，为了减轻确定性频率行为，已经实施了一些补救措施，例如在日内市场引入¼-h产品，对平衡责任方进行更严格的监管，以及协调欧盟指导方针。本文分析了这些措施的有效性，并对实施以来频率行为的发展进行了评估。此外，还提出了目前的趋势和根本原因，以及今后可能需要采取的进一步措施。
