摘要:

由于氢具有许多优点(例如,无污染、来源广泛、储运方便等优点,氢基多能源系统(HMESs)受到广泛关注。然而,现有的HMES优化运行的工作忽略了建筑热动力学,这意味着建筑热负荷的灵活性不能被用来降低系统的运行成本。在本文中,我们研究的HMES的最佳操作问题,考虑建筑热动力学。具体来说,我们首先制定了一个预期的运营成本最小化问题有关的HMES。由于存在不确定的参数、不明确的建筑热动力学模型、与三种储能系统和室内温度相关的时间耦合的运行约束以及电能子系统和热能子系统之间的耦合,求解该问题具有挑战性。为了克服这一挑战,我们将问题转化为马尔可夫博弈,并提出了一种基于多智能体离散行为者-评论者规则(MADACR)的能量管理算法来解决这个问题。该算法不需要任何不确定参数的先验知识,不需要参数预测,也不需要建立显式的热动力学模型。基于真实轨迹的仿真结果表明了该算法的有效性。

英文摘要:

Since hydrogen has many advantages (e.g., free pollution, extensive sources, convenient storage and transportation), hydrogen-based multi-energy systems (HMESs) have received wide attention. However, existing works on the optimal operation of HMESs neglect building thermal dynamics, which means that the flexibility of building thermal loads can not be utilized for reducing system operation cost. In this paper, we investigate an optimal operation problem of an HMES with the consideration of building thermal dynamics. Specifically, we first formulate an expected operational cost minimization problem related to an HMES. Due to the existence of uncertain parameters, inexplicit building thermal dynamics models, temporally coupled operational constraints related to three kinds of energy storage systems and indoor temperatures, as well as the coupling between electric energy subsystems and thermal energy subsystems, it is challenging to solve the formulated problem. To overcome the challenge, we reformulate the problem as a Markov game and propose an energy management algorithm to solve it based on multi-agent discrete actor-critic with rules (MADACR). Note that the proposed algorithm does not require any prior knowledge of uncertain parameters, parameter prediction, and explicit building thermal dynamics model. Simulation results based on real-world traces show the effectiveness of the proposed algorithm.
