针对电-热综合能源系统中可再生能源输出的不确定性和间歇性问题,提出用于一种电-热综合能源系统能量管理的强化学习方法,以电-热综合能源系统运行成本最低为目标,实现综合能源系统的能量管理。首先,建立电-热综合能源系统能量管理模型;然后,将含可再生能源的电-热综合能源系统能量管理过程转化为马尔可夫决策过程;再次,在DQN-CE(深度Q网络-交叉熵)的基础上进一步提出采用NoisyNet(噪声网络)和自注意力机制来提高智能体优化性能;最后,通过算例分析表明,所提方法训练的智能体能够实时响应可再生能源的不确定性,并能在线管理包含可再生能源在内的电-热综合能源系统的能量。
To address the uncertainty and intermittency of renewable energy output in integrated electricity-thermal energy systems, a reinforcement learning method for energy management is proposed, aiming to minimize the operating costs of the system. First, an energy management model for the integrated electricity-thermal energy system is established. Next, the energy management process of the system, which includes renewable energy, is transformed into a Markov decision process (MDP). Thirdly, on the basis of DQN-CE(Deep Q-Network-Cross Entropy), we further propose a NoisyNet and self-attention mechanism to improve the agent optimization performance. Finally, case study analysis shows that the agent trained using the proposed method can respond in real time to the uncertainties of renewable energy and manage the energy of the integrated electricity-thermal energy system with renewable sources online.
