At present, the fourth industrial revolution that is emerging is deep integration of information technology and industry, which is triggering far-reaching industrial changes and forming new production methods. Intelligent manufacturing such as intelligent equipment and smart factories based on information physics systems is leading the transformation of manufacturing methods. The "Made in China 2025" issued by the State Council in 2015 pointed out that structural adjustment should be regarded as a key link in building and manufacturing a strong country, vigorously develop advanced manufacturing industries, and transform and upgrade traditional industries. In 2016, the National Development and Reform Commission, the National Energy Administration, and the Ministry of Industry and Information Technology jointly issued the "Guiding Opinions on Promoting the Development of "Internet +" Smart Energy" and "Made in China 2025 - Energy Equipment Implementation Plan", 2018, Industry and Information The Ministry of Chemical Industry and the National Energy Administration issued the "Smart Photovoltaic Industry Development Action Plan (2018~2020)" to promote the development of the intelligent and intelligent new forms of the energy industry.
Intelligent is the foundation
Specifically, the "Guiding Opinions on Promoting the Development of "Internet +" Smart Energy" pointed out that with reform and innovation as the core and "Internet +" as the means, based on intelligence, it promotes the deep integration of energy and information. Among them, in the intelligentization of energy production and consumption, encourage the construction of intelligent wind farms, smart photovoltaic power stations, etc., to encourage the intelligent transformation of coal, oil, gas mining, processing and utilization of the entire chain; in the intelligentization of energy consumption, involving intelligence Factory, smart home, intelligent community, smart city; in terms of network construction, based on smart grid, it is interconnected with various types of networks such as heat pipe network, natural gas pipe network and transportation network. In the "Made in China 2025 - Energy Equipment Implementation Plan", intelligent manufacturing and intelligent operation and maintenance have penetrated into 15 fields including coal, electricity, oil, gas, nuclear power, new energy, fuel cells, energy storage equipment and power grid. The Smart Photovoltaic Industry Development Action Plan (2018-2020) aims to build an intelligent photovoltaic industry ecosystem, improve the intelligent manufacturing level of the photovoltaic industry, and promote the integration of the Internet, big data, artificial intelligence and other photovoltaic industries, and promote the photovoltaic system. Full-process intelligent control of exploration, design and integration into operation and maintenance. In addition, the content related to the smart cities that have been hot in recent years has focused on intelligent power, gas, transportation and other improvements in people's livelihood.
From the perspective of policy documents, the prerequisite for realizing smart energy is to complete intelligent transformation. And this is the focus of the energy industry is now under construction.
The concept of smart power plant is still under discussion and hot discussion
At present, the discussion about digital power plants, smart power plants, and smart power plants in the society is endless, but there is no uniform standard for its definition and connotation.
The China Automation Society jointly organized the well-known units of the electric power industry such as Guangdong Electric Power Research Institute, State Grid Zhejiang Electric Power Research Institute, State Grid Henan Electric Power Research Institute, Zhejiang Energy Technology Research Institute, Shanghai Minghua Power Technology Engineering Company, etc. The definition of smart power plant technology development defines that smart power plants refer to technologies that integrate intelligent sensing and execution, intelligent control and management decision-making based on the extensive adoption of modern digital information processing and communication technologies to achieve safe, efficient, environmentally friendly operation and intelligence. A power plant with coordinated power grids. China Energy Research Association Energy Conservation and Emission Reduction Center and North China Electric Power University held the 2018 Smart Power Plant (Phase 1) Forum in May, Shi Yubo, Executive Vice President of China Energy Research Association, believes that the essence of smart power plants is information technology and intelligent technology. The high level of development and deep integration in the field of power generation is mainly reflected in the systematic application of technologies such as big data, Internet of Things, visualization, advanced measurement and intelligent control. The core of its technology is information fusion and intelligent power generation technology. Liu Jizhen, an academician of the Chinese Academy of Engineering and former president of North China Electric Power University, believes that the concept and characteristics of intelligent power generation are based on the digitalization, automation, informationization and standardization of power generation processes, with the integration of management and control, big data, cloud computing and Internet of Things. Integrate intelligent sensing and execution, intelligent management and optimization, intelligent management and decision-making technologies to form an intelligent power generation operation control management mode. The development of intelligent power generation needs to go through the process from primary form to advanced form, from partial application to system application; it needs to make breakthroughs in basic theory, key technologies and engineering applications; it needs to realize the innovation of theory, technology and system and mechanism. Wang Congsheng, director of the Science and Technology Information Department of China Energy Construction Group Co., Ltd., admits that many smart power plants are currently focused on information, visualization, digitization, big data, etc., but with these conditions, it does not mean that this power plant has Wisdom, called "smart power plant" is more appropriate. Feng Weizhong, deputy chairman of Shanghai Waigaoqiao No. 3 Power Plant and general manager of Shanghai Shenneng Power Technology Co., Ltd., said that “smart power plantsâ€, which are built with information, digitization, networking, big data and intelligence, can only be called For the "smart power plant", and the construction of smart power plants is inseparable from people, we should make full use of human wisdom to innovate.
Active attempts of intelligent power plants and hydropower stations

Smart power plant, smart dispatch, and smart maintenance business unit construction.
Smart PV is the first to win
Intelligent photovoltaic power plants have achieved cross-border integration earlier and have been widely used. On March 20th, 2014, the industry's first intelligent photovoltaic power station site was held in Golmud. The concept of smart photovoltaic power station was first proposed at the meeting, and it was pointed out that smart photovoltaic power station is the trend and trend of the industry. The former State Council Counselor Shi Dingxi said at the meeting: "Smart PV is the trend and trend of the industry. It has been well applied and achieved great results. Huawei's smart PV solution incorporates its leading digital information technology and 4G wireless technology in the world. , Internet technology and core chips, software and other technologies, so that "Internet + photovoltaic" has been implemented, and has been applied to scale, making China's photovoltaic power station and the communications industry as the world's forefront." It is reported that Huawei's "smart photovoltaic" concept It includes digitizing the power station and realizing high-precision digitization of all equipment of the photovoltaic power station. The equipment is perceptible, connectable and controllable. Re-engineering photovoltaic power plants through digital power generation, digital transmission, and digital management, and moving toward true intelligence. These technologies include providing data foundation through big data mining, analysis to achieve fault pre-judgment, and proactive preventive operation and maintenance; using intelligent drone inspection, developing intelligent photovoltaic power generation monitoring system with intelligent cleaning prediction, alarm expert, and proximity matching Machine dispatch service and other functions.
