Mr. Liao Zhihua, Technical Director of Guangzhou Lili New Energy Technology Co., Ltd. and Executive Director of Wuhan Precise Electronic Technology Co., Ltd., has been committed to promoting and building the best form of carrying new power systems, and relying on digital technology to empower new power systems and new equipment " Observable, measurable and controllable” capabilities, mainly in the following scenarios:

It is estimated that by 2030 and 2060, the proportion of new energy power generation in my country will exceed 25% and 60%, respectively, and the new power system presents a high proportion of power electronic characteristics. In view of this, Mr. Zhihua believes that it is necessary to develop new inertia support resources, develop new control technologies in new energy and energy storage, and improve the ability of power electronic power supplies to support system inertia. Second, in terms of new power transmission equipment scenarios, green energy surplus areas generally have harsh external environments, and new power systems with a high proportion of new energy will be greatly challenged by external environmental hazards. In view of this, Mr. Liao Zhihua believes that it is necessary to study and apply new technologies such as the cloud, the big thing, the mobile intelligence chain, etc., to realize equipment operation and maintenance, power grid operation, and environmental monitoring. The third aspect is that in terms of new substation equipment scenarios, the installed capacity of new energy has increased significantly, and large-scale new energy is connected to the grid. Its randomness and volatility will not only increase the risk of abandoning wind and light, but will also exacerbate the peak summer season. During the winter, problems such as heavy overload, harmonics and short circuit of transformers will affect the operation and maintenance of transformer equipment. Mr. Liao Zhihua believes that it is necessary to build a powerful "computing power" for new substation equipment, and rely on the Internet of Things to connect the perception, analysis, decision-making and other links of substations, so that based on the perception ability, it can be given new decision-making and execution capabilities.

Promoting the deep integration of digital and physical power systems is a systematic project, which should follow the laws of technological evolution, tap the potential of new equipment, and promote major transformation of the power system. Over the years, Mr. Liao Zhihua, on the one hand, has built a deeply integrated "industry-university-research-use" innovation system, and jointly carried out the research and development of core technical equipment; , leading the deep integration of digital and physical power systems.
