In recent years, with the acceleration of global power transformation, our country’s power structure is rapidly moving towards cleanup.
On the one hand, the scale of my country’s new dynamic equipment continues to rise. As of the end of December 2024, my country’s wind power generation machine exceeded 1.4 billion kilowatts for the first time. Among them, the capacity of solar power generators was about 890 million kilowatts, an increase of 45.2% year-on-year; the capacity of wind turbines was about 520 million kilowatts, an increase of 18.0% year-on-year.
On the other hand, my country’s new dynamics maintains a high proportion of consumption outlook. In 2024, when the total power generation of wind solar energy in my country reached 18,300 kilowatts, a year-on-year increase of 27%. The application rate of wind-light power generation remains above 95%, and the power generation continues to increase, and the proportion is progressing smoothly.
The development of new forces is trending. With the large scale connection and wide distribution of new forces, the Internet’s operation environment has undergone significant changes. The Internet in different areas has gradually shown the Internet’s characteristics from strong to weak, which has also brought new topics to ensuring the safe and stable operation of the Internet.
The strong power system of my country has been built for many years, and its overall power system currently presents strong network characteristics. Joe Sugar daddy, deputy general engineer of the Jinfeng Zero Carbon Energy Industry Department, introduced that he became a second-line star and became a first-line star with online technology, and his resources were coming in a lot. A familiar control strategy can realize the new power unit to quickly adjust its output based on parameters such as network frequency and voltage, ensuring basic concurrent network operation stability, so that the new power and power can be input into the Internet in an orderly manner, and supply power with traditional power to meet current power needs.
“When the proportion of new power connections in the department area is close to 30% – 40%, the Internet will begin to show weak network characteristics.” Joe Yuan said, “When the shortcomings of network technology will be convex, the power and power equalization difficulty will rise, and the voltage and frequency adjustment will be recurring./”>Escort goes to the Sugar daddy step, and the system moves the habitsManila escort decreases, and resistance to force can reduce the weakness. ”
Under the comparison, network-type energy-energy technology as a voltage source can independently set voltage parameters and output stable voltage and frequency, which can be operated online or off the Internet, providing more flexibility and independence for power supply. It can better respond to the challenges brought by ultra-high proportions of new power connections, effectively enhancing the stability and reliability of the Internet. Therefore, network technology has become the focus of energy-enhancing enterprise competition market.
New Problems and New Opportunities under New Power Systems
Now, my country is transforming from a traditional power system with synchronous generators to a “double-high” new power system with high proportion new power and high proportion power electronics equipment.
Compared with the traditional power system mainly directed by synchronous generators, the “double-high” power system has obvious characteristics such as low-age, low damping, and weak voltage support. Moreover, our network presents a AC-DC transmission and receiving end strong coupling and voltage-level complex network shape. It is difficult to coordinate between the transmission and receiving end and the high-low pressure-level network, and it is easy to cause a chain reaction after problems.
In terms of specificity, some power networks in the southeastern areas such as Qinghai, Xinjiang, Xidiao, and the Sugar daddy new power bases built on the Gobi, desert and desert, have a high proportion of new power connections, and the thin network is also lacking in common power support. A high proportion of intermittent renewable power brings challenges to the Internet’s stability, power balance and backup support.
The study and discussion confessed that as the power electronic equipment transmittance increases, the power network short-circuit ratio drops, and the system is reliable and reliable. Various types of power network support equipment need to be arranged. If the current network technology route is extended, when the power electronic equipment transmittance reaches 50%, the systemIf the short-circuit ratio drops to 2.5, the stability will face. Even if equipment such as synchronous adjustment cameras are arranged, the maximum limit of the transmission rate and short-circuit ratio can only reach 75% and 1.5%, which is difficult to effectively meet the challenges posed by high-receiving power electronic equipment.
Take Australia as an example, in this country, the distribution of power resources is uneven, and many renewable power generation facilities are far away from the middle of the load, and long distance transmission is required. In order to realize the safety and stability of power supply under high renewable power transmission rate, we propose to vigorously develop network technology.
Construction network energy storage technology enhances the stability of the network in terms of differences and solves the problem of low short-circuit ratio by using various techniques such as analog synchronous generator characteristics, optimizes network tide distribution, improves defective crossing capabilities and provides damping characteristics. It not only can charge and discharge efficiently, but also act as a “stable pressure device” for the Internet, which can provide guarantees for the safe and stable operation of the Internet. The network energy storage system further stabilizes the Internet voltage waveform and high power quality, while reducing regional or part of the Internet wave.
As the demand for network energy is becoming increasingly prominent, national departments have continuously issued policies to encourage the development of network energy.
In October 2023, the National Bureau of Dynamics issued the “Notice on Organizations to Demonstrate the Try to Demonstrate the Development of Renewable Dynamics”, and planned to implement a guideline project by 2025, which includes a network-based technical demonstration of new power-enhancing energy-enhancing structures, and is highly praised by him. Technical research and development and engineering demonstrations such as network-type radio, network-type photovoltaic power generation, network-type energy transmission, and new power low-frequency group network transmission.
August 2024Sugar daddy, the National Development and Transformation Commission, the National Power Bureau, and the National Data Bureau cooperated to issue the “Action Plan for Accelerating the Construction of New Power Systems (2024-2027)”, which clearly proposed to promote the application of network technology, and based on the operation needs of high-proportion new power power system, select the Internet-type control technology for the application of typical scenarios, and have the ability to actively support the Internet voltage, frequency, and power angle stable to ensure the stable operation of the power system.
In terms of policy, it includes Westward hiding, Xinjiang, Inner Mongolia, Fujian, etc.CortAll provincial, municipal and autonomous regions within the provinces, cities and counties have introduced corresponding policies to support the development of network energy and to prepare camera targets.
Rail veterans have insight into the new future of network energy storage
With the support of national-level guiding policy regulation and machine targets, the industry bidding progress has accelerated significantly since the second half of 2023, and there has been incomplete statistics. As of June 2024, China has completed bidding for 2.3GW/7.6GWh network energy storage project.
The demand for network energy-energy market has increased, and enterprises have been continually deploying it. In 2024, many companies such as Nanrui Energy Aviation Products and Plans have made significant progress in network energy aviation technology and have successfully implemented network energy aviation projects.
Join shows that power electronic equipment has its own unique advantages over traditional power generators, that is, it can flexibly adjust parameters based on algorithms, and actually pass through the machine continuously, enhancing the network. At present, various energy companies are actively seeking Sugar baby to promote the healthy development of the entire energy industry.
Taking the Xinjiang Dazaka City Network Energy Accumulation Project that uses gold-wind zero-carbon self-contained energy storage systems as an example, the project not only meets the high and low temperature and high-wind sand environment in Xinjiang; it can also supply the system with a 300% rated current in 10 seconds and provides c TC:
