差异化民营热电市场协调

Differentially-Private Heat and Electricity Markets Coordination

Lesia Mitridati, Emma Romei, Gabriela Hug, Ferdinando Fioretto

摘要:

已经确定,热电系统之间的部门协调是向更可持续的能源系统过渡的一种节能和成本效益高的方式。然而,序贯市场的协调依赖于市场运营商之间敏感信息的交换,即用户负荷的时间序列。为了解决这种交换所产生的隐私问题,本文介绍了一种新的隐私保护Stackelberg机制(w-PPSM),产生不同的私人数据流高保真。建议的w-PPSM强制执行的隐私保护数据的可行性和保真度相对于原始问题,通过后处理阶段,以实现接近最优的市场之间的协调。在一个现实的能源系统中的多个数值模拟证明了w-PPSM的有效性,它实现了高达两个数量级的减少相比,传统的差分隐私机制的隐私成本。

英文摘要:

Sector coordination between heat and electricity systems has been identified has an energy-efficient and cost-effective way to transition towards a more sustainable energy system. However, the coordination of sequential markets relies on the exchange of sensitive information between the market operators, namely time series of consumers' loads. To address the privacy concerns arising from this exchange, this paper introduces a novel privacy-preserving Stackelberg mechanism (w-PPSM) which generates differentially-private data streams with high fidelity. The proposed w-PPSM enforces the feasibility and fidelity of the privacy-preserving data with respect to the original problem through a post-processing phase in order to achieve a close-to-optimal coordination between the markets. Multiple numerical simulations in a realistic energy system demonstrate the effectiveness of the w-PPSM, which achieves up to two orders of magnitude reduction in the cost of privacy compared to a traditional differentially-private mechanism.
