论文摘要
已经确定了热量和电力系统之间的部门协调，具有一种节能且具有成本效益的方式，可以过渡到更可持续的能源系统。但是，连续市场的协调依赖于市场运营商之间敏感信息的交换，即消费者的负载时间序列。为了解决此交易所引起的隐私问题，本文介绍了一种新颖的保护隐私stackelberg机制（W-PPSM），该机制生成具有高忠诚度的差异私有数据流。拟议的W-PPSM通过后处理阶段实现了有关原始问题的可行性和保真度，以实现市场之间的近距离协调。与传统的差异性机制相比，现实能量系统中的多次数值模拟证明了W-PPSM的有效性，该拟合的有效性最多可减少两种数量级的隐私成本。
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.
