能源互联网接入设备关键技术探讨

作为能源系统与信息系统信息-物理深度融合的庞大网络,能源互联网"开放共享"的特征对用户侧能源的接入、控制和传输提出了挑战。针对能源互联网背景下用户侧综合能源管理问题,首先提出了能源互联网接入设备的概念,指明了其区别于能源路由器的特征,并从规划调度、运行管理和能源服务3个维度详细介绍了能源互联网接入设备的应用领域。然后,重点介绍了设备特征识别、需求响应、区块链、大数据、综合能源管理和电力市场等6项关键技术,并深入阐述了能源互联网接入设备与这些关键技术的紧密联系。最后,简要介绍了能源互联网接入设备的实施方案和未来挑战,以期为未来能源互联网下用户设备高效便捷入网提供一些借鉴和参考。

Discussion on key technologies of energy internet access equipment

As a huge network involving deep cyber-physical integration of energy systems and information systems, energy internet possesses features of open and sharing, which brings challenge to the access, control and transmission of energy on user side. Aiming at the issues of integrated energy management on user side in the context of energy internet, the concept of energy internet access equipment is proposed as well as its features that obviously differ from energy router. Then, from the perspectives of planning and dispatching, operation management, and energy service, the application fields of energy internet access equipment are thoroughly introduced. Next, six key technologies included in energy internet access equipment are described, including equipment feature recognition, demand response, blockchain, big data, integrated energy management and electricity market, from which the relationship between energy internet access equipment and these key technologies is elaborated. Lastly, the engineering implementation and future challenge of energy internet access equipment are briefly introduced, hoping to provide some reference and guidance for effective and convenient access of user-side equipment to energy internet in the future.
