Zero carbon self-recycling!

The first new smart microgrid system in China was launched in Fuzhou University

  Science and Technology Daily News (Wang Yixi, Chen Huifang, reporter Xie Kaifei) Provide zero-carbon clean energy about 300,000 degrees per year, reduce carbon dioxide emissions by about 258.37 tons, and reduce sulfur dioxide emissions by about 61.46 kg... Recently, the reporter learned from the School of Electrical Engineering of Fuzhou University, The first domestic "source-network-load-storage" microgrid system independently researched and developed by a university, integrating teaching, scientific research, product display and other production, teaching and research, has successfully operated, which can provide for the local consumption of distributed clean energy and the realization of zero-carbon buildings It also provides a demonstration application scenario of "source network load storage" for the implementation of the country’s entire county’s photovoltaics, which has the value of promotion and application in campuses, industrial parks and other occasions.

  It is understood that the system was developed by the Fuzhou University Green Smart Energy Internet Industry-Education Integration Innovation Base, which integrates clean energy photovoltaic and wind power generation, electrochemical energy storage, smart power distribution, and smart electricity use.

In response to the random volatility, uncontrollability of solar photovoltaic power generation, and the time mismatch with the evening power load, the base uses a containerized "green smart energy storage system" for green power storage to achieve zero-carbon clean energy Time and space transfer.

When night falls, the smart lighting system can obtain electric energy from the energy storage system, and realize green energy use through LED energy-saving lamps, forming a complete new microgrid of "source network load storage" from green power generation, green power storage to green smart power consumption system.

  According to Associate Professor Lin Qiongbin, the head of the system development team: "The'wisdom' of the system is embodied in multiple dimensions, such as electrical connections between systems through smart power distribution cabinets, and coordinated operation and intelligent control through smart monitoring platforms. Among them, smart The power distribution cabinet has the'four remote' functions of'remote measurement, remote signaling, remote control, and remote adjustment'. The intelligent monitoring platform collects data from each system in real time and uses intelligent algorithms to predict the power curve of photovoltaic power generation." In addition, the system also realizes storage It can realize the real-time perception of the system status and online estimation of the battery health status, and use the intelligent control of lighting load based on big data and artificial intelligence dynamic planning algorithms, so as to realize the "zero-carbon" intelligent coordinated operation of the "source-network-load-storage" microgrid system.

  Professor Xu Zhihong, Dean of the School of Electrical Engineering of Fuzhou University, said: “Under the background of the country’s strategic goal of advancing the energy transition, the School of Electrical The research and development and breakthrough of nanotechnology have also cultivated and delivered more outstanding talents for the industry to serve the carbon peak and carbon neutral goals."
