摘　　要：多园区综合能源系统协同调度是实现园区间能源互济互补,提高资源配置效率的重要手段。由于各园区通常隶属于不同利益主体,多采用分布式调度方法确定多园区协同调度方案。然而,分布式调度方法中多轮迭代过程的边际信息交互将引发园区发用能参数的隐私泄露风险,限制了园区参与协同调度的积极性。为此,文中提出了基于差分隐私的多园区综合能源系统分布式调度方法,通过添加拉普拉斯扰动解决了多轮迭代过程中的隐私泄露问题。随后,提出了适应分布式调度的扰动衰减算法以提升所提方法的收敛性。最后,通过算例验证了所提方法的有效性,并分析了差分隐私下各园区总运行成本变化情况。The coordinated dispatch of multi-park integrated energy systems is a crucial means to achieve energy complementarity between parks and improve resource allocation efficiency.Since different parks usually belong to different interest entities,distributed dispatch methods are used to determine multi-park coordinated dispatch schemes.However,the marginal information exchange in the iterative process of distributed dispatch poses a risk of privacy leakage of energy generation/consumption parameters,which limits the enthusiasm of parks to participate in coordinated dispatch.To address this issue,this paper proposes a differential privacy based distributed dispatch method for multi-park integrated energy systems.By adding Laplace disturbance,the method addresses the privacy leakage problem during multiple iterations.Subsequently,a disturbance attenuation algorithm adapted to distributed dispatch is proposed to enhance the convergence of the method.Finally,case studies verify the effectiveness of the proposed method,and the changes in total operating costs of each park with differential privacy are analyzed.This work is supported by National Natural Science Foundation of China(No.52107115).
