摘要: 分布式微电网作为能源互联网重要的组成部分,可优化分布式可再生能源的利用,通过与分布式数据中心的融合,又可降低数据中心对传统非清洁能源的依赖和碳足迹。但是由于潜在的安全和隐私问题会引起能源市场的不透明性和不确定性,从而导致可再生能源的使用率和交易率低下。本文引入了一种机遇式的任务调度策略,通过对数据中心计算负载的动态调整,从而优化在站式可再生能源的利用率;在此基础上,提出了基于区块链的动态智能合约制定方法,以有效降低用户的经济开销并提高运营商的经济收益。最后,通过实际光伏发电数据与数据中心负载数据对上述方法进行评估,仿真实验证明,上述方法对分布式可再生能源的利用率以及买卖双方的经济收支方面表现出良好的效果。

Abstract: As an important part of energy internet, the micro-grid can facilitate integration of distributed renewable energy sources and data centers, in order to reduce brown energy consumption and carbon footprint. However, due to potential security and privacy issues caused by opacity and uncertainty of the energy market, it led to a lower renewable energy utilization and transaction rates. This paper introduces an opportunistic task scheduling strategy to improve utilization of on-site renewable energy by dynamically adjust the workload of data centers. In addition, the authors proposed a dynamic smart contract formulation based on blockchain, which effectively reduces the expenses of users and improves the benefits of the operator. Finally, the simulations with a real-world task workload and solar power traces demonstrate that the above methods can significantly improve the utilization of renewable energy and optimize the revenue for both users and operators.
