Abstract

Modeling electricity markets realistically plays a crucial role for understanding complex emerging market dynamics and guiding policy making. In systems with a high share of variable renewable generation, accurately modeling the behavior of storage units can be particularly challenging, as their bidding strategies depend on expected electricity prices. While there exist a wide variety of electricity market models, they typically rely on rule-based bidding strategies or optimization approaches, which may not be sufficient to represent competitive and strategic behavior on the market. In this paper, we present a multi-agent deep reinforcement learning modeling framework that allows representing competitive and strategic behavior of energy storage units. This framework can be executed in large-scale electricity market models, thus facilitating market design analyses. We show that the proposed approach performs very well when compared with widely used modeling approaches, and its computational efficiency makes its use in energy market modeling practical.
基于多智能体深度强化学习的电力市场存储单元参与建模
电力市场的实际建模对于理解复杂的新兴市场动态和指导政策制定起着至关重要的作用。在可变可再生能源发电比例较高的系统中,准确建模存储单元的行为尤其具有挑战性,因为它们的竞标策略取决于预期电价。虽然存在各种各样的电力市场模型,但它们通常依赖于基于规则的竞标策略或优化方法,这可能不足以代表市场上的竞争和战略行为。在本文中,我们提出了一个多智能体深度强化学习建模框架,该框架允许表示储能单元的竞争和战略行为。该框架可在大规模电力市场模型中执行,便于市场设计分析。研究表明,与目前广泛使用的建模方法相比,该方法具有很好的性能,其计算效率使其在能源市场建模中具有实际意义。
