To adapt to the new trends and requirements of civilization evolution, humanity must fundamentally solve the driving force of civilization progress, and achieve the safe, stable, clean, and sustainable use of energy. In 2009, the academic community proposed that interconnected technology would change the way the entire human world operates, involving the work and lives of billions of people, thus giving rise to the concept of "building a smarter Earth"; In the concept of 'Smart Earth', there is also the concept of 'Smart Energy'.

What is smart energy

Smart energy is a form of energy that fully develops human intelligence and capabilities, integrates human unique wisdom into the entire process and various links of energy development, utilization, production, and consumption through continuous technological innovation and institutional changes, establishes and improves energy technology and energy system systems that meet the requirements of ecological civilization and sustainable development, and presents a form of energy. In short, smart energy refers to a form of energy that possesses human brain functions such as self-organization, self-examination, self balancing, and self optimization, and meets the requirements of systems, safety, cleanliness, and economy.

The carrier of smart energy is energy. Smart energy requires humans to apply more wisdom to the energy consumption process and use energy more intelligently; Using less energy to achieve the same or even greater effect. Through it, humans comprehensively utilize various forms of energy to achieve limited and full utilization.

The essence of smart energy is wisdom. The wisdom of smart energy is precisely integrated into the technological innovation of energy development and utilization.

The driving force behind smart energy is technology. The technological innovation of steam engines and internal combustion engines is the foundation of industrial civilization, and the development of smart energy also requires technology to promote it. New technologies for the development and utilization of energy sources such as nuclear energy, solar wind energy, and biomass energy will undoubtedly provide tremendous impetus for the development of smart energy.

Vivid Practice of Smart Energy

The smart energy system, which integrates energy, intelligence, and technology, presents a vivid practical case in the Yongfeng Industrial Park in the northwest of Beijing. Visiting this park leaves the impression that energy conservation and emissions reduction are everywhere! This project contains too much 'wisdom'!

It is the comprehensive smart energy project of China Power Zhongdian Intelligent North Science and Technology Industrial Park under State Power Investment Corporation.

Throughout the entire park, facilities related to smart energy are ubiquitous:

Entering the gate of the park, what catches the eye is a beautiful charging carport. Yes, you heard it right. It's a charging shed that can charge electric vehicles; The difference between it and a regular carport is that its ceiling is covered with photovoltaic panels, and inside the carport, there are charging stations. The workers in the park drive their electric cars over in the morning, park their cars in this charging shed, plug in the charging wires, and at night they can go home fully charged.

Climbing onto the roof of the park, one can see buildings of all sizes covered in photovoltaic panels and wind turbines, fully utilizing solar and wind energy to generate electricity.

In slightly more remote areas of the park, energy storage "big boxes", cooling towers, and gas internal combustion engines are installed.

Of course, there are still some equipment in the entire park that are "hidden" and silently contribute to the energy conservation, consumption reduction, and intelligent operation of the park!

According to Mao Xiaolei, Deputy Chief Engineer of China Electric Power Zhongdian Intelligent Technology Co., Ltd., Beike Industrial Park was built in 2004, covering an area of 70 acres and a total construction area of 63152 square meters; At present, a total of 14 enterprises have settled in the park, with a high concentration of companies in the biopharmaceutical industry. In 2017, the electricity consumption of the park was 13 million kWh, and in 2018, the electricity consumption increased to 16 million kWh. The capacity and reliability of the park's energy system are no longer able to meet the needs of the park's enterprises, which has constrained the park's investment attraction. In August 2018, China Electric Power Zhongdian Smart and Beike Yongfeng Technology Development Co., Ltd. signed an energy management agreement to provide a package of smart energy solutions for Beike Industrial Park. Through multi energy complementarity and integrated optimization, the park will provide comprehensive energy services including electricity, heat, and cooling.

After taking over the energy management of the park, China Electric Power Zhongdian Smart has tailored a smart energy solution for the park from the aspects of "source, grid, load, storage, and control":

Open source: By adding internal combustion engines, rooftop photovoltaics, and intelligent photovoltaic carports, an additional 1600kW of power load has been added to the park; By combining cooling, heating, and power with existing equipment, we provide comprehensive energy supply for the park, achieving multi energy complementarity.

Departmental network: Connecting the original scattered cooling and heating systems separately, planning them uniformly, and using them as backups for each other, greatly improving the reliability of energy supply in the park; Add one 1250KVA transformer to evenly distribute the load carried by each section of the busbar; Deploy an electric energy monitoring system.

Load increase: Meet the expansion needs of the computer center while providing stable two-way power supply for it; Design user side management functions to achieve intelligent control.

Expansion of storage: Build a new 100kW/500kWh lithium iron phosphate battery to achieve peak shaving and valley filling, and improve power quality.

Intelligent Control: Implement intelligent transformation, break through information barriers, and achieve real-time monitoring and intelligent control of electricity, cooling, and heating sources; Deploy the multi energy flow energy management system jointly developed by China Electric Power Zhongdian Intelligent and Tsinghua University to comprehensively optimize and dispatch various equipment and energy sources in the park.

Through a series of renovations, the park has achieved multi energy coupling of cold heat electricity gas, and perfect coordination of source grid load storage. People are able to manage energy in a more refined and dynamic way, thus helping energy to always be in a "smart" state. Through deployment, the energy utilization rate of the park has been improved, easily saving nearly 30% of energy; Since the project was put into operation, a total of approximately 1136 tons of carbon emissions have been reduced, 451 tons of standard coal have been saved, and approximately 60000 equivalent trees have been planted.

Intelligent energy has extraordinary value

Today, responding to global energy challenges and leading energy development with intelligence is becoming a global consensus, and "smart energy" with new technologies, models, and formats as its core is the practical solution for the current energy revolution.

National Power Investment closely follows the national strategic deployment, embraces intelligent technology, uses Internet technology, big data and other intelligent means to empower energy development, and build a smart energy system: work with the China Power Enterprise Confederation, together with energy enterprises, universities and scientific research institutions, launched the establishment of the China Smart Energy Industry Alliance, which provides a platform for the integration of political, industrial, academic, research and use of resources, and improves the scientific research, management level and competitiveness of China's smart energy industry; Take the lead in promoting a comprehensive smart energy park similar to the China Electric Power North Technology Industrial Park; Building a zero carbon town in Xiong'an New District and a low-carbon smart energy supply island in Pingtan... With efficient utilization and circular utilization as the core, we aim to construct a multi energy complementary and supply-demand coordinated smart energy system, providing energy integration solutions for smart energy construction.

Undoubtedly, smart energy has extraordinary value, not only promoting energy conservation and emission reduction, but also promoting the construction of ecological civilization. Therefore, it is urgent to build a smart energy information system to ensure national energy security.

Building a smart energy information system to ensure national energy security

In order to implement the overarching policies of the Party and state leaders in energy utilization, State Power Investment Corporation has established a smart energy platform company: China Energy Integration Smart Technology Co., Ltd; And through this company, it takes the lead in building a national smart energy information platform to provide Chinese wisdom and solutions for promoting the deep integration of energy with the Internet, big data and artificial intelligence.

This platform is known as the "National Energy Brain", which gathers energy data from various aspects such as hydropower, wind power, photovoltaics, and nuclear power across the country. Through platform construction, the information silos of energy data can be opened up, enabling real-time collection and monitoring of national energy data; With the help of the management backend, one can have a comprehensive view of the national energy data; In the future, the platform can also achieve nationwide energy dispatch, achieving "everything under control" in energy regulation. For example, many comprehensive smart energy parks such as China Electric Power Corporation's North Science and Technology Industrial Park can achieve intelligent coordination and scheduling of energy.

The national level smart energy information platform built by State Power Investment Corporation based on China Energy Integration will enable it to grow into a national energy big data service platform, an innovative highland of smart energy technology, and a promoter and advocate of the smart energy industry ecology, providing guarantees for energy security and efficient operation.

Guided by the ideology of socialism with Chinese characteristics in the new era, China will become the protagonist of a new round of energy revolution. State Power Investment Corporation (SPIC) has made continuous efforts in recent years to develop energy technologies, drive transformation and development through technological innovation, gradually establish an open and shared smart energy ecosystem, promote the deep integration of digital technology, intelligent technology and energy industry, and continuously contribute "full positive energy" to promote the transformation of the energy industry, achieve the safe, stable, clean and sustainable use of energy in China, and ensure national energy security.
