Sergio Rozada, Dimitra Apostolopoulou, Eduardo Alonso

摘要:

基于微电网的架构的兴起极大地改变了配电系统中的能量控制景观,使得分布式控制机制对于确保可靠的电力系统操作是必要的。在本文中,我们提出使用强化学习技术来实现负载频率控制,而无需中央机构。为此,我们近似的最佳解决方案的主要,次要的,和三级控制与使用的多智能体深度确定性策略梯度(MADDPG)算法。发电机组的特点是作为代理人,学习如何最大限度地提高其长期性能的行为和与环境的相互作用,以平衡发电和负载在一个具有成本效益的方式。在我们的框架中,网络效应也被建模,用于将频率恢复到标称值。我们通过数值结果验证了我们的强化学习方法,并表明它可以用于以分布式和成本有效的方式实现负载频率控制。

英文摘要:

The rise of microgrid-based architectures is heavily modifying the energy control landscape in distribution systems making distributed control mechanisms necessary to ensure reliable power system operations. In this paper, we propose the use of Reinforcement Learning techniques to implement load frequency control without requiring a central authority. To this end, we approximate the optimal solution of the primary, secondary, and tertiary control with the use of the Multi- Agent Deep Deterministic Policy Gradient (MADDPG) algorithm. Generation units are characterised as agents that learn how to maximise their long-term performance by acting and interacting with the environment to balance generation and load in a cost efficient way. Network effects are also modelled in our framework for the restoration of frequency to the nominal value. We validate our Reinforcement Learning methodology through numerical results and show that it can be used to implement the load frequency control in a distributed and cost efficient way.
