'Every major energy transformation is guided by technological progress.' IEC Vice Chairman, Chairman of State Grid Co., Ltd. Shu Yinyu said that in the global energy transformation, standard construction will play an important role. And 'virtual power plant' related standards construction, for Energy transformation in the direction of clean low carbon is of great significance.
State Grid 'Virtual Power Plant' standard is internationally recognized
On September 21st, hosted by State Grid Co., Ltd. and the International Electrotechnical Commission, hosted by Weibei Electric Power Company, the awarding ceremony of the 'Energy Transformation' high-end forum and international standard innovation base attended by many academicians of the Academy of Engineering was held in Beijing. State Grid announced that Its two 'virtual power plant' standards have been approved by the IEC.
Founded in London in 1906, the IEC is the world's oldest and most influential international electrical standardization organization. It plays an important role in promoting global energy transformation. For more than a century, IEC has published internationally in the field of electrical engineering. Standard 7713, has made an important contribution to the promotion of sustainable development of electricity and energy.
It is understood that due to the wide application prospects of virtual power plants, the world is taking the lead and striving for strategic initiative. Standard development has become a battleground for leading international discourse rights. In October 2017, State Grid Corporation organized Yubei Power Company and China Power The team of experts from the Academy of Sciences, on behalf of China, submitted the 'Virtual Power Plant' "Use Case" and "Architecture and Functional Requirements" proposals to the IEC. After fierce competition, it was approved in March 2018. This means that the IEC is in the 'virtual power plant'. The first international standards established in the field fell to China.
What is a 'virtual power plant'? Du Xiangyu, an academician of the Chinese Academy of Engineering who attended the forum, explained that 'virtual power plant' is not a power plant in the traditional sense, it is equivalent to a power 'smart butler'. It stands at the grid, in photovoltaic power generation, wind power, etc. When the energy sources are intermittent, they are organized by energy storage devices to form a stable and controllable 'large power plant', which is convenient for handling various relationships with the large power grid.
Wang Xing, Ph.D., Electrical Engineering, Brunel University, UK, interviewed by Xinhua News Agency's Economic Information Daily, said that the virtual power plant is an invisible power plant and a decentralized energy source. Polymer. In this aggregate, the power user is a consumer or a producer. For example, a user who owns an electric car has a relatively surplus power at night, and charges the car when the electricity price is low. The electricity is relatively tight during the day, and the electricity price is also When it is higher, it can be sold to the grid. In such a polymer, power generation and electricity are balanced by self-regulation.
'In simple terms, the virtual power plant is the 'source network load' aggregation management mode under the Internet + smart energy environment, user-centered, and commercialized market. ' Party Secretary, Deputy General Manager of Weibei Power Trading Center Co., Ltd. Wang Xuanwen said that virtual power plants will have broad application prospects in distributed power supply, northern clean heating, user-side demand response, electric vehicles, etc. Virtual power plants can be 'connected' from distributed photovoltaic, energy storage equipment, thermal storage boilers and Controllable load to achieve maximum efficiency of cooling, heat and electricity. In the prosperous urban buildings, virtual power plants can monitor central air conditioning, flexible controllable loads such as electric vehicles, environmental parameters and distributed energy output in real time, around users. And system requirements, automatically adjust and optimize response quality, reduce investment in power and grid construction, and achieve a win-win situation for users and systems, technology and business models while creating a comfortable and comfortable living environment.
Vice Chairman of IEC, Chairman of State Grid Co., Ltd. Shu Yinyu said that distributed energy makes the main body of the grid connected to both the power generation side and the electricity supplier. The complexity of the grid operation increases the uncertainty significantly. The 'virtual power plant' is essentially new. The upgrade of the first generation of power systems will provide solutions for cracking clean energy consumption and green energy transformation.
Significant for China's energy clean transition
Experts attending the conference believe that as a solution to crack clean energy consumption and green energy transformation, the two international standards of 'virtual power plant' have fallen into China, which marks the international community's full recognition of China's energy transformation and green development. China's and global energy clean transition is of great significance.
In the keynote speech, Shu Yinyi made three basic judgments on energy transformation. First, clean low carbon is the basic direction of energy transformation. On the basis of continuously promoting the clean utilization of fossil energy and improving energy efficiency, vigorously develop and utilize non-fossil energy, especially Wind power, solar power and other new renewable energy sources have become the universal choice of countries. Second, re-electrification is the fundamental path of energy transformation. From the perspective of production, it is reflected in the conversion of non-fossil energy from more and more electric energy. It will mainly come from non-fossil energy, especially renewable energy. From the perspective of terminal consumption, it is reflected in the unprecedented expansion of the utilization of electric energy. The traditional fossil energy consumption market such as transportation has obvious electric energy substitution trend, and electricity will become a modern support. The main energy varieties of the information society and the digital economy. The future beautiful society will surely be a highly electrified society. The third is to build a new generation of power systems that are the foundation for energy transformation. The new generation of power systems will be widely interconnected and intelligently interactive. Flexible and flexible, safe and controllable, open sharing features of the new power system .
'As the world's largest energy consumer, China has been at the forefront of the world's energy clean transition in recent years.' Shu Yinhao pointed out that in the use of clean energy, China's wind power, solar power installed capacity grew at an average annual rate of 40 years from 2008 to 2017. % and 191%, much higher than the global average growth rate of 19% and 46%. By the end of 2017, China's renewable energy installed capacity reached 650 million kilowatts (water 340 million, wind 160 million, light 130 million kilowatts), accounting for 36.6 %, slightly lower than (38) in Europe (38%), far higher than the US 19.6%. In the process of re-electrification, since 2000, the proportion of global energy in terminal energy consumption has increased from 15.4% to the current 19%. , increased by about 4 percentage points; China increased from 14.8% to 23.5%, an increase of about 9 percentage points. It is estimated that by 2030, global and Chinese electricity will account for 24% and 30% of the total energy consumption.
According to Shu Yinxuan, with the deepening of energy transformation, the function of the power grid and the operation mode have presented an unprecedented test. Wind energy, solar energy and other clean renewable energy sources are all random, intermittent, volatility characteristics, large-scale, A high proportion of access to the grid, resulting in huge peaking and FM voltage, resulting in weakening of the system's moment of inertia, brings a series of new challenges to the balance regulation of the power system and the safe and stable operation of the grid. Moreover, in the past, a large and medium-sized power grid only needed access. Dozens, hundreds of power plants, one-way power transmission from the production side to the consumer side; now with the development of new energy technologies and integration with digital technologies, the grid will access thousands, or even thousands of types of power supplies. With a large number of new interactive energy-using devices, many grid-connected entities have both producer and consumer identities, and the complexity of grid operation and uncertainty have increased significantly.
It is in this context that the 'virtual power plant technology' aimed at 'providing solutions for cracking clean energy consumption and green energy transformation' has emerged. It adapts to the needs of energy transformation and promotes the evolution of traditional power grids from functional to energy Internet. From the technical upgrade to the new generation of power systems, its physical characteristics, structural form, operating mechanism, and control methods are significantly different from those of traditional power systems, and are considered to be the key to the continued deepening of energy transformation.
Promote energy clean transformation with standard construction
'The wave of energy transformation cannot be lacking in international standards. There must be no Chinese voice in the formulation of international standards.' Gabriela Ehrlich, director of the IEC Global Public Affairs and Publicity Department, said at the forum that the two international standards of 'virtual power plant' will be given to China. State Grid Corporation, let the world look forward to the international wisdom of China.
Cui Gang, director of the Standard Innovation Management Department of the State Administration of Markets Supervision at the forum, believes that international standards, as the world's 'universal language', are the basic norms of interconnection between countries, the basic conditions for technical cooperation, and the role of promoting energy transformation. More and more important. National Grid Corporation has been striving to promote the development of UHV, smart grid, clean energy and other technologies, actively implement clean alternatives and alternatives to electric energy, vigorously promote the construction of a global energy Internet, and embark on the innovation and development of a Chinese grid enterprise. Road, in order to promote energy transformation, has made a series of pioneering innovations, providing a Chinese solution for the world's energy transformation.
Cui Gang said that the large-scale development and utilization of new energy is the core measure. The comprehensive re-electrification of energy production and consumption is the basic approach. Interconnection, intelligent and efficient modern power grid is the basic platform. Technological innovation is the core of energy transformation, and the global energy sector Actively exploring new technologies and promoting new developments. Taking the lead in achieving technological breakthroughs and realizing technological innovations will surely become the leader in energy transformation. By preparing and publishing international standards, State Grid Corporation will not only help lead energy transformation and upgrading, but also promote relevant The industry is moving towards the high end, promoting the realization of China's creation.
'Without standardization, energy transformation cannot be successful.' Shu Yinyin talked about the significance of standards for promoting energy transformation, stressing that, from the perspective of interaction, new devices, new users, new technologies, new There are a large number of methods, and it is urgent to strengthen the standard construction, focus on filling the standard gap, improve the integrity, interactivity and compatibility of the standard system, and provide uniform specifications for the close connection of all links and efficient coupling. Second, from the perspective of ensuring the safety and quality of the power system, In promoting China's energy transformation, we must give priority to ensuring safety and quality, continuously improve the standard system, promote the intrinsic safety construction of power grids, and realize the controllability of power system security. 3. From the perspective of promoting international energy cooperation and exchange, Economic globalization is developing in depth, energy and power infrastructure interconnection and capacity cooperation are accelerating, and it has become a priority area of 'One Belt, One Road' construction. Strengthening international standards cooperation and mutual recognition, and promoting cooperation in infrastructure interconnection and capacity cooperation in various countries. The problems encountered in the process of energy transformation will certainly play a positive role in promoting.
According to Shu Yinxuan, under the strong support of the State Administration of Markets, the National Standards Commission, the National Energy Administration and other relevant parties, the State Grid Corporation has actively adapted to the new situation of energy production and consumption revolution in recent years, giving full play to the hub of the power grid in the energy system. The role of the platform, actively promote the innovation and development of the power grid, and promote the construction of the standard system. For example, a series of standards have been established in the fields of UHV, smart grid, renewable energy access, electric vehicle charging and replacing, etc., promoting the formation of 1512 industry standards, the state Standard 701. At the same time, actively participate in the development of international standards, initiated five new technical committees in the IEC, more than 600 company experts involved in IEC work, promoted the formation of 59 international standards, including 43 IEC standards, 16 IEEE standards, The company has become an important force in the development of international standards.
'The world needs standards to develop synergistically, and standards promote world connectivity.' Cui Gang said that the proposed international standard for virtual power plants was approved, marking the national grid's position as an international leader in the field of virtual power plants for the new generation of power systems. The right to speak of international standards of transition has important practical significance and long-term strategic value.
