德国对可再生能源的投资额远远领先于将其纳入电力市场和电网所需的基础设施。对于提供灵活性的存储和其他技术来说，德国当前的监管框架和市场设计仍然是未来投资的障碍。本文提出了经济高效的储能部署的监管障碍，并使用电力市场上存储技术多功能运行的通用优化模型进行了评估，该模型能够考虑不同的市场和监管设计变化。由于电网限制对于间歇性资源整合的重要性日益凸显，以及配电网层面即将推出的新型创新存储技术，电网被纳入该模型。这种方法可以对市场运行和电网拥塞之间的相互作用进行定量分析。以德国北部的 110kV 高压电网作为典型的拥堵电网为例，该电网由于风能渗透率高而持续限电。存储技术以及需求方和发电管理等其他措施将需要灵活的市场和复杂的监管设计，以便为未来的能源系统显着增加价值。
Investment volumes in renewable energies in Germany are far ahead of the necessary infrastructure to integrate them into both the electricity market and the grid. For storages and other technologies offering flexibilities the current regulatory framework and the market design in Germany remain a barrier for upcoming investments. In this paper regulatory barriers for an economically efficient energy storage deployment are presented and evaluated using a generic optimization model for a multifunctional operation of storage technologies on electricity markets capable to consider different market and regulatory design changes. Due to the rising significance of grid restrictions for the integration of intermittent resources and upcoming new innovative storage technologies on distribution grid level, the electricity grid was integrated into the model. Such an approach enables a quantitative analysis of interaction between market operation and grid congestion. This is shown using a 110kV high-voltage grid in the North of Germany as a representative congested grid with ongoing curtailments due to high wind energy penetration. Storage technologies - and also other measures as demand-side and generation management - will need a flexible market and a sophisticated regulatory design in order to significantly add value to the future energy system.
