In response to the severe situation of power supply guarantee, in addition to the power generation side doing a good job in cross-provincial and cross-regional power mutual assistance and emergency power supply, the response to the power demand of end users is also particularly important. Recently, power grids in many places have established power load management centers to support the power demand-side management work to a new level.
What is a power load management center?
It is understood that the Power Load Management Center is established by local power grid enterprises based on local actual conditions, responsible for the construction and operation of the new power load management system, cooperate with the government to organize orderly electricity use and demand response, and carry out power load data monitoring, statistical analysis, emergency drills and other work. The provincial power load management center will concentrate professional forces in accordance with the principle of "priority for demand response, orderly electricity use guaranteed, and power saving assistance", and coordinate the power load management work in various provinces. At the same time, we will continue to accelerate the construction of new power load management systems, improve relevant technical standards and management specifications, and provide strong support for ensuring the safety of power supply and promoting the consumption of new energy.
As an important tool for configuring and managing power resources, the load management system is an important tool for unified management, unified regulation and unified service of load resources. It can realize precise load regulation under the requirements of safe supply of power and normalized and refined energy management of users.
According to relevant requirements, all high-voltage power users of 10 kV (6 kV) and above are included in the load management scope. The user load access for newly installed electricity should be designed, constructed, accepted and put into operation simultaneously with the user's power reception project. The existing user loads should be connected to the load management system in batches. In principle, orderly electricity users should be given priority access according to the power gap warning level in various places.
Why set up a power load management center?
At the end of May 2022, the National Development and Reform Commission and the National Energy Administration jointly issued the "Notice on Promoting the Construction of a New Power Load Management System", which deployed the work of strengthening power operation regulation, deepening power load management, and establishing a power load management center. The country requires that before the peak winter in 2022, all localities will basically build load management systems, and strive to achieve a load control capacity of 5% of the maximum load in the region. Among them, areas with tight supply and demand situations in summer should be built before the peak summer.
The establishment of the Power Load Management Center is in line with the decisions and deployments of the CPC Central Committee and the State Council on the safety and supply of energy and electricity.
At present, the power loads in many places in my country have repeatedly set new highs, and the peak summer of electricity is in a critical period. The establishment of a power load management center is an important guarantee for alleviating the continuous tight power supply and demand situation, effectively improving the level of power load management, and ensuring people's livelihood electricity and reliable power supply. Establishing a power load management center to change the power usage mode through power demand-side management of users and improve terminal energy usage efficiency, becoming an important means for many provinces to experience peak summer season.
What is the role of the power load management center?
The completion of the Power Load Management Center has a positive effect on ensuring the safety of power supply, improving the level of energy consumption service, and improving the economic benefits of users.
1. Ensure safe supply of electricity
The establishment of the Power Load Management Center is conducive to the precise implementation of power control and the safe supply of electricity. Taking Jilin as an example, during this year's peak summer, Jilin ProvinceElectric loadIn addition, the three-level power load management centers of Jilin Province, municipal and county power load management centers implement 7×24-hour duty during key periods of power supply, monitor the changes in power customers' load in real time, and carry out normalized monitoring during the remaining periods to fully ensure people's livelihood electricity use.
2. Improve the level of energy consumption service
The Power Load Management Center can provide governments and users with load monitoring, demand response, safe power use analysis and other services in normalized demand management, explore load regulation capabilities, carry out load management work in a refined manner, and improve the level of energy use services.
Tianjin Power Load Management Center has developed modules such as intelligent operation and maintenance, building energy consumption optimization, and at the same time, load classification management and flexible control are realized by installing energy efficiency terminals on the load side. Through a series of measures for energy use management, Tianjin has gradually formed a variety of load aggregation models including industry and commerce, photovoltaics, energy storage, electric vehicles, microgrids, load integrators, etc. Up to now, Tianjin has formed a multi-time and multi-category adjustable load resource pool, with an adjustable load of 5.61 million kilowatts, involving more than 18,000 users, playing an important role in ensuring power supply during peak summer seasons.
3. Guide users to receive subsidies through power demand response
The power load management center can ensure the smooth operation of the demand response mechanism. In July this year, the Tianjin Electric Power Load Management Center screened and found that an automobile parts company in Binhai New Area consumed a large amount of electricity, and the load peak-to-valley difference was greater than 80%. During peak electricity consumption, the company can help the power grid to throttle peak by lowering the load, and can also obtain response subsidies.
The company's equipment engineering department manager said that he received a lot of subsidies after participating in the demand response of peak shaving and peak cutting of power grids. During the peak period of electricity consumption during the day, enterprises reduced their electricity load by an average of 10,000 kilowatts. After adjusting the construction period, they stepped up production to complete customer orders at night. Within 20 days, they received a government subsidy of 173,900 yuan.
It is reported that the Jilin Provincial Power Load Management Center will also build a Jilin Province power demand-side management platform during peak summer this year, and build a demand-side response load resource library that is no less than 5% of the historical maximum power load scale of Jilin Province.
