/ Chaowen Tong/August 11, 2022 Guangzhou -- Zhou Tao, General Manager of China Energy Net, and Yang Lifan, Senior Architect of Schneider Electric Power Grid Industry Solutions, at the "Green Energy Management Winning Plan Second Quarter -- Fan Expo" recently. Observations and insights on "Macro trends, technological paths and Innovations under the Construction of new power systems" were shared.
Under the dual-carbon target, the construction of new power system with new energy as the main body is accelerating. "The explosive growth of new energy, while restructuring the power system, will prompt the industry to face up to and accelerate the solution to the energy 'impossible triangle'," Zhou said. Specifically, with a large proportion of new energy connected to the grid, the new power system will show the characteristics of the integration of source and network and load interaction, and the compatibility and complementarity of "big power supply, big power grid" and "distributed system". Technically, all links are digitized and the dispatching and operation system is highly intelligent. In the system, the market will play a decisive role in the allocation of power resources. Among them, digital and intelligent technology is the core drive to build a new power system. The deep integration of energy technology and digital technology is the key to break the impossible triangle of 'safety-economy-green'."
Yang Li Fan thinks: "Under the new power system, the performance of supply and demand is more 'disordered', the whole power system physical world is' increasing entropy '; In contrast, information systems must become more 'ordered', showing a 'decrease in entropy'. The essence of the new power system evolution is to promote the integration of the information system and the physical system, 'entropy loss' against 'entropy increase', from the generation side to the grid side to the load side to find a balance."For the current distribution network urgent problems to be solved such as efficient and safe access to distributed power supply, fault detection and isolation, power quality monitoring, distributed power planning and operation, Yang Fan says, "Artificial intelligence, digital twin, AC-DC hybrid power grid will be the three 'sharp tools' to boost the digital and intelligent transformation of power grid. Artificial intelligence technology can play an important role in different aspects such as planning and design, protection and control, operation management, as well as in different scenarios such as new energy output prediction and load prediction, ground fault identification, circuit breaker health prediction, non-invasive load identification and decomposition. Digital twin technology significantly improves the visibility, interactivity and intelligence of power grid data through modeling and data mapping. Hybrid AC-DC grid technologies will increase the capacity and efficiency of distributed energy access more effectively."
< /p>Facing the increasingly complex energy scene and accelerating release of digital demand, Schneider Electric, through the "Green Energy Management Win Plan", together with ecological partners, carried out joint technological innovation based on the real scene demand, at the same time, is launching a series of "Win Sharing". By gathering more profound and authoritative expert resources, it is expected to provide the operating enterprises and a wider range of ecological partners with systematic guidance and greater empowerment at different levels from macro insight, market demand and technical path.
