Abstract The current organization of the internal electricity market in Europe relies on a zonal market system: the European power system is divided in bidding zones, electricity trades within a bidding zone can occur in an unconstrained manner, while electricity trades between bidding zones are limited by cross-zonal capacities. Two approaches can be used to calculate and allocate cross-zonal capacity: the coordinated Net Transmission Capacity (NTC) approach or the flow-based approach. In Central Western Europe, the flow-based approach is implemented for the day-ahead market since 2015. To avoid undue discrimination between internal and cross-border power exchanges, a minimum threshold of 70% on the cross-zonal capacity available for trade will be enforced in a near future. Such a threshold could significantly impact the socio-economic welfare and its distribution between the various actors. However, no assessment of the impacts of such a threshold has been performed so far, in particular because no convincing approach exists to perform such an assessment (e.g. security constraints and redispatch neglected). This paper develops such an approach and demonstrates its applicability on a case study, in order to assess the impact of a minimum threshold on cross-zonal capacity in a flow-based market.

基于流量的市场跨区域容量最低阈值的影响评估

摘要 欧洲内部电力市场目前的组织方式依赖于区域市场体系：欧洲电力系统划分为投标区，投标区内的电力交易可以不受约束地进行，而投标区之间的电力交易受到限制。跨区域容量。可以使用两种方法来计算和分配跨区域容量：协调净传输容量 (NTC) 方法或基于流量的方法。在中西欧，自 2015 年起就对日前市场实施了基于流量的方法。为避免内部和跨境电力交易之间的不当歧视，可用于贸易的跨区域容量的最低门槛为 70%。近期内实施。这样的阈值可能会显着影响社会经济福利及其在各个参与者之间的分配。然而，迄今为止尚未对此类阈值的影响进行评估，特别是因为不存在执行此类评估的令人信服的方法（例如忽略安全限制和重新调度）。本文开发了这种方法并证明了其在案例研究中的适用性，以评估最低阈值对基于流量的市场中跨区域容量的影响。
