欧洲电力市场的设计是基于区域市场和统一价格。因此，在这些区域内不提供有区别的位置价格信号。如果区域内的拥塞是由于电网扩张的缺失而发生的，那么这种市场设计就揭示了其内在的不完整性，并可能导致严重的短期和长期扭曲。在本文中，我们研究这些扭曲，重点是在区域市场下的限制电网扩张的影响。因此，我们使用欧洲电力系统的长期模型，并限制每十年输电网的允许扩张。我们发现，一个不完整的市场设计和限制电网扩张的组合导致了发电能力的分配不当，无法将电力输送到需要的地方。这导致一些地区的能源不平衡高达2-3%，并且难以实现电力行业预期的政治目标。
The European electricity market design is based on zonal markets with uniform prices. Hence, no differentiated locational price signals are provided within these zones. If intra-zonal congestion occurs due to missing grid expansion, this market design reveals its inherent incompleteness, and might lead to severe short and long-term distortions. In this paper, we study these distortions with a focus on the impact of restricted grid expansion under zonal markets. Therefore, we use a long-term model of the European electricity system and restrict the allowed expansion of the transmission grid per decade. We find that the combination of an incomplete market design and restricted grid expansion leads to a misallocation of generation capacities and the inability to transport electricity to where it is needed. This results in an energy imbalance in some regions of up to 2-3% and difficulty when reaching envisaged political targets in the power sector.
