How to promote the construction of smart grid
日期：2020-07-14
Smart grid is the exploration and practice of the future development form of power grid. It needs to comply with the development trend of energy transformation and the requirements of energy revolution, comprehensively accelerate the construction of smart grid in the new situation, and realize the high-quality development of energy and power. The development of smart grid should focus on the intrinsic safety, overall efficiency and public utility attributes of power system, and give full play to its advantages as an industrial platform. At the same time, promoting the construction of smart grid requires the government, grid enterprises and the whole society to participate in, coordinate and form a joint force.
The transformation of energy and power puts forward new requirements for the development of power grid
Since entering the industrial civilization, the use of fossil energy has greatly promoted the development of human civilization, but at the same time, it has brought about some practical problems, such as resource depletion, environmental pollution, climate change, energy security and so on. In the new round of global scientific and technological revolution and industrial reform, the deep integration of Internet concept, advanced information technology and energy industry has also had a profound impact on the transformation and development of the energy industry. In the new era, China actively promotes energy transformation and energy revolution, and strives to build a clean, low-carbon, safe and efficient modern energy system, which puts forward new requirements for the development of power grid.
Power consumption growth still has potential, the level of electrification continues to improve, and the development of power grid needs both scale and quality. In order to deal with the contradiction between the people's growing needs for a better life and unbalanced and inadequate development in the new era, we need to continue to adhere to high-quality economic development. Compared with the development level of developed countries in the world, there is still a great potential for the growth of China's electricity demand in the future. With the deepening of China's economic restructuring and upgrading of terminal energy consumption, the level of electrification will continue to improve. The scale of power grid, especially the construction of medium and low voltage power grid, will continue to expand, and the demand for reliability and quality of power supply will be further improved.
In the new era, power security and green development put forward higher requirements for power grid. Under the requirements of the overall national security concept in the new era, the importance of energy and power supply security is gradually highlighted. The safe and stable operation of the power system plays a key role in ensuring the stable development of the national economy. As the proportion of renewable energy continues to increase, the construction of larger scale and larger-scale AC / DC hybrid power grid will affect the operation characteristics of power grid to varying degrees. The further promotion of power market-oriented reform will also produce more complex and diverse system operation modes, which put forward higher requirements for the safe operation and management level of power grid.
Smart grid is the exploration and practice of the future development of power grid. In recent years, the concepts of "digital power grid" and "Internet of things" are consistent. However, the development goals of "digital power grid" and "Internet of things" are consistent. As early as 2015, China issued the "guidance on promoting the development of smart grid", which clearly promotes the construction of smart grid. In the process of continuous practice, it is also gradually found that the development of smart grid should not be limited to the intelligent and informatization of power grid, but should focus on the future energy development, study and judge the development direction and route of power grid; in the construction process, we should not only put all kinds of flowers in bloom, but also focus on the central positioning of power grid development and focus on solving the core problems.
Three suggestions on promoting smart grid construction
In view of the large scope, wide range of influence and great challenges of smart grid construction, it is necessary for the government, grid enterprises and the whole society to jointly participate, coordinate and form a joint force to gradually form a favorable environment for the development of smart grid and accelerate the implementation of smart grid.
Do a good job in top-level design and strengthen industry guidance. Adhere to planning first, further organize and deepen the research on Smart Grid Based on the new situation and new requirements, clarify the technical route and development mode of smart grid development in the new era, establish and improve the relevant standard system of smart grid, and promote the international cooperation and innovation of smart grid; comprehensively strengthen the guidance of industry development, and strengthen the coordination among various industries, so as to indicate the future development of smart grid Direction.
Pilot demonstration should be carried out first and coordinated. We should encourage pilot demonstration, carry out the construction of various innovation demonstration projects according to local conditions, strengthen the scientific evaluation and closed-loop management of innovation demonstration projects, focus on the technical economy and market prospects of innovation demonstration projects, gradually explore the formation of replicable and popularized experience and achievements, and lead the scale construction of smart grid through pilot demonstration.
We should improve the supporting mechanism and cultivate innovative soil. Gradually improve the supporting policy system of smart grid, and provide policy support in project construction, grid connection, transaction, etc.; improve the relevant mechanism construction, cultivate an open and shared market environment, support the healthy development of energy forms such as energy storage, micro grid, distributed energy, etc.; promote the construction of smart grid innovation and entrepreneurship system, guide all parties to participate, stimulate the development vitality of the industrial chain, and cultivate Cultivate innovative soil.
Accelerating the construction of smart grid in an all-round way is an effective way to implement the requirements of energy transformation and energy revolution in the new era. We should accurately grasp the development orientation of smart grid in China's new situation, scientifically plan a reasonable and feasible development route, lead the construction of smart grid with innovation and demonstration, and promote the high-quality development of energy and power industry.
