Coordinated heat and power dispatch has attracted increasing attention due to its flexibility support for renewable energy accommodation. Different from most conventional studies that regard coordination as holistic optimization, in which power systems monopolize the additional payoff brought by coordination while heating systems suffer from higher heat supply costs, this work considers coordinated dispatch from a novel multi-party perspective to ensure the privacy protection, mutual benefit, and mutual trust of all participants. Based on the existing works that address the privacy issue well, we propose a transfer payment strategy to ensure that both heating systems and power systems benefit from coordinated dispatch. The calculation of transfer payments is performed through a parametric programming method, which discloses only the payoff variation and maintains the privacy of the payoff itself. Finally, a critical region tracking method is developed to confirm the authenticity of the information exchanged between power systems and heating systems, which prevents possible defrauding. Numerical tests indicate that our proposed approach achieves the mutual benefit of both systems in coordinated dispatch and detects inauthentic information effectively to ensure mutual trust.

互利互信协调热电调度:多方视角

协调热电调度因其对可再生能源消纳的灵活性支持而引起越来越多的关注。不同于大多数将协调视为整体优化的传统研究,即电力系统垄断协调带来的额外收益,而供热系统的供热成本较高,本工作从新颖的多方角度考虑协调调度,以确保隐私保护,互惠互利,所有参与者相互信任。基于现有的解决隐私问题的工作,我们提出了一种转移支付策略,以确保供热系统和电力系统都受益于协调调度。转移支付的计算是通过参数化编程方法进行的,它只披露收益变化并维护收益本身的隐私。最后,开发了一种关键区域跟踪方法来确认电力系统和供热系统之间交换的信息的真实性,从而防止可能的欺诈行为。数值测试表明,我们提出的方法在协调调度中实现了两个系统的互惠互利,并有效地检测了不真实的信息以确保相互信任。
