"The Internet of Things (IoT) in power distribution not only enables the interconnection of power facilities, but also greatly changes the lifestyle of every citizen and promotes sustainable urban development. The Hangzhou demonstration zone is the first pilot area for the State Grid Corporation's future Internet of Things in power distribution. Next, the entire Zhejiang province will continue to improve and promote this technical architecture." Chen Lei, head of the Distribution Division of the Equipment Management Department of State Grid Zhejiang Electric Power Co., Ltd., is full of confidence in the future.
In 2019, Zhejiang Electric Power Company will fully promote and apply the distribution Internet of Things (IoT) construction model that has been verified in the Hangzhou demonstration zone, the Hangzhou Bay Ubiquitous Power IoT Provincial Comprehensive Demonstration Zone (including Ningbo Eastern New City, Shaoxing Binhai New City, Huzhou Moganshan, and Taizhou Dachen Island), the Ningbo Meishan Smart Energy County-level Demonstration Zone, and the Wuzhen Internet Light Park-level Demonstration Zone.
As one of the first units to implement the State Grid Corporation's "Distribution Internet of Things" (IoT) initiative, State Grid Hangzhou Power Supply Company actively promotes the construction of the Xiaoshan Qianjiang Century City Distribution IoT Demonstration Zone. Starting from actual production needs and aiming to solve the professional pain points and difficulties in distribution network operation and maintenance and user services, the company actively implements the "cloud-pipe-edge-terminal" distribution IoT architecture. It explores and practices distribution IoT technology centered on the new intelligent distribution transformer terminal (TTU), deepens the integration of operation, distribution, and dispatch information, and achieves full control over the status of distribution equipment, full penetration of business processes, and online, transparent, mobile, and intelligent processing of distribution business and information. This comprehensively improves the level of distribution network operation and maintenance management and the quality of power supply services.
Furthermore, the Jiaxing Wuzhen Internet of Things (IoT) Power Internet of Things Comprehensive Demonstration Project has been listed as one of the eight key park-level comprehensive demonstration projects of the State Grid Corporation of China, and has built a "Ubiquitous Power IoT" technology exhibition hall. As the main window for the State Grid Corporation of China to showcase its power IoT technology, this year, around the 2.3 square kilometer Wuzhen Summit venue area, the State Grid Corporation of China has constructed a data-integrated, open, shared, flexible, and controllable park-based energy internet ecosystem. By using energy data to promote digital city construction and data services for people's livelihoods, it has formed a "Wuzhen experience" that can be learned from, replicated, and promoted.
To support the construction of a smart city in Nanjing Jiangbei New Area, Jiangsu Province, and to create a demonstration zone for the distribution Internet of Things in Jiangbei New Area, State Grid Nanjing Power Supply Company, guided by the development needs of green and smart cities, has achieved panoramic data management, transparent operation status, intelligent diagnosis and decision-making, and rapid service response, thus promoting the transformation of the distribution network from the traditional operation and maintenance model to the smart operation model.
