中文摘要:

随着可再生能源的发展和分布式电源的推广，电网需求侧能效管理工作将逐步由集中式优化调度计算转向分布式计算。物联网技术和区块链技术的进步将为实现能效管理系统的分布式系统提供技术基础。文章提出了一种基于物联网智能电表和微电网的多用户分布式能效管理系统，并通过提出的非合作博弈论模型对家用电设备进行调度计算，成功实现了降低用户家庭电费支出和整个社区微电网能耗总成本的目标。用户可在家庭的分布式能源、社区微电网以及公用电网三种中择优选择购电，并在博弈中优化自己的日常家电使用策略，使得市场所有用户都可将能源消耗成本降至最低，实现纳什平衡。在此基础上，该模型运用区块链技术为参与者之间提供可靠的、安全的、私密的通信媒介，实现用户家电设备的智能监控,通过智能合约对用电量进行计费。算例分析结果表明，该方法能最大限度地降低能耗总成本和各用户能耗成本。

英文摘要:

With the development of renewable energy and the spread of distributed generation, energy efficiency management on the power grid demand side will gradually shift from centralized optimal scheduling calculation to distributed computing. The progress of Internet of things and block chain technology will provide the technical foundation for the distributed system of energy efficiency management system. In this paper, a multi-user distributed energy efficiency management system based on Internet of things smart meter and micro-grid is proposed, and the scheduling calculation of household appliances is carried out through the non-cooperative game theory model, which successfully achieves the goal of reducing the household electricity expenditure of users and the total micro-grid energy consumption cost of the whole community. Users can choose to purchase electricity among three kinds of household distributed energy, community micro-grid and public grid, and optimize their daily household appliance use strategies in the game, so that all users in the market can reduce the energy consumption cost to the minimum and achieve Nash equilibrium. On this basis, the model uses block chain technology to provide reliable, secure and private communication media between participants, so as to realize intelligent monitoring of household appliances of users and charge electricity consumption through smart contracts. The results of an example analysis show that this method can reduce the total energy consumption cost and the energy consumption cost of each user to the greatest extent.
