With the autumn rain and the cold, the electricity flows in summer are getting closer.
This year, during the peak summer period, Zhejiang faced severe situations such as the highest even temperature, the highest power load, and the least uncertain external power supply in the same period. Before the rain, the Zhejiang Power Co., Ltd. of China has started to explore how to better ensure supply guarantee this winter and next summer, as well as how to better achieve supply guarantee price in combination with short-term and long-term goals.
One of the purpose of exploring the actual design is the scientific governance of air conditioning burden. Zhejiang’s power-related responsible persons said that we must strive to achieve “kilowatts controllable and adjustable” and achieve “kilowatts controllable and must control, and adjustable as much as possible”.
Why focus on air conditioning and burden control?
The source of the problem of ensuring stable supply is closely related to the supply and demand.
From the supply side, Zhejiang itself has weak power resources, and the proportion of foreign-provincial electricity loads has continued to be about one-third, and there is a significant “inconclusiveness” in foreign electricity. With the construction of a new power system, the proportion of new power is getting higher and higher, and there is also a significant “inconclusiveness” in the output of new power. In 20Sugar babyIn 21 years, the highest power load in Zhejiang Province was 100.22 million kilowatts, and the largest peak and valley difference reached 38.03 million kilowatts, and only 14 hours were achieved when the highest load was 97%. The scale of the network is obviously uneconomic when it is peaking.
From the demand perspective, among the overdue load demand in Zhejiang Province in summer, air conditioning has accounted for nearly 40% of the proportion of air conditioning and decreasing load, becoming one of the main factors that show the large peak and valley gap of the Internet and the convex peak load, bringing huge pressure to the Internet’s stable operation and the protection of electricity for daily use. In other words, the reason why the power supply is heavy in peak summer and peak winter is that the demand for temperature loads such as air conditioning is comforted. This also shows that through administrative, economic, technical and other skills, we will strengthen the control of air and control the energy efficiency of the whole society, and burn our eyebrows.
The two “inconclusive” peak characteristics of adding supply guarantees can be seen that in addition to continuously developing power in supply, strengthening consumption-reducing dives in the consumption side, it will be more useful to help peak cutting. At present, Zhejiang Electric Power has turned its attention to the airLoyal to control.
According to the “2021 Zhejiang Provincial Economic and Social Development Statistics Public Report”, Zhejiang Province has air conditioning 217.9 platforms per 100 customers.
Stately, the province’s summer temperature load drop (mainly air conditioning) has a maximum of 38.2 million kilowatts, accounting for nearly 40% of the society’s highest debt; the summer heat load (including heat-breathing equipment such as heat-breathing machines) has a maximum of 20.6 million kilowatts, accounting for more than 22% of the society’s highest debt load.
Modeling and manufacturer research methods have found that the negative load change rate of air conditioning setting temperature is mainly affected by the setting temperature and environmental temperature. The smaller the gap between indoor setting temperature and environmental temperature, the more significant the load drops will be whenever 1 degree Celsius is adjusted. When the environment temperature in summer is 38 degrees Celsius, the air conditioning temperature setting is 1 degree Celsius per hour, and the negative load of the use of the power is about 7% to 8%; when the environmental temperature in summer is 1 degree Celsius, the negative load of the air conditioning temperature setting is about 6% for every 1 degree Celsius per hour.
In addition, analyzing data from Yunpingtai, a manufacturer of electricians, found that the temperature setting of air users in Zhejiang Province is generally not up to the request for “26 degrees Celsius in summer and 20 degrees Celsius in winter”. If the above request can be strictly implemented, and after calculation, it is theoretically possible to reduce the maximum load of 7.3 million kilowatts and 2.9 million kilowatts in the summer and winter seasons of the province, which will greatly reduce the Internet pressure during peak peaks. With the development of economic and social development and career progress, air traffic has spread across thousands of enterprises, with multiple measures and widespread focus, and is difficult to manage challenges and problems. Zhejiang Province has a large number of air conditioning applications, ranking among the top three in the country, with many types and brands, and the technical routes and governance platforms are not exactly the same. At the same time, the construction of air conditioning perception also faces a series of problems such as difficulty in evaluating, difficulty in communication, and difficult maintenance.
Zhejiang Power has developed its strength from five aspects: expert, goal, mechanism, route and platform, locking up various application scenarios, and seeking problems to be solved one by one.
FromThe mechanism is based on the Sugar daddy. Zhejiang Power strives to promote the air-regulating burden governance mechanism of various levels of power governance departments, industry authorities for the governance body and power supply companies, and divides the administrative area into network responsibility to form government-enterprise cooperation. As of now, power supply companies in Zhejiang Province and cities have established a debt management center authorized by the bureau. In the future, Zhejiang Power will strengthen the cooperation mechanism with Yunpingtai, a major night sky-control brand service provider.
From the technical route, Zhejiang Power has customized air conditioning perception to build a technical plan, and has classified it into four major technical paths, including basic monitoring, enhanced monitoring, minute-level control, and third-party platform sharing.
From the platform construction, Zhejiang Power will build a digital platform based on the new power load control system, build an intelligent air conditioning control system architecture, build an air conditioning load control driving, promote the interconnection of air conditioning load information, and the classification and classification of second-line stars to become first-line stars, and resources are coming in a hurry. Governance; based on branch industry emptySugar baby‘s “label” and form a red orange and blue green “fiveSugar daddycolor warning map”, implement color warning, classification governance, and branch measures, and accurately implement policies for the bureau; deepen the “one-key response” application and perception construction, and in accordance with the principle of “fitting as much as possible, adjusting, from big to small, from simple to complex”, strive to complete the reform of 5,000 business and 1,500 public institutions within the year, and complete 50% in 2023 and 100% commercial and non-industrial perception equipment installation by 2024.
Based on the basis of the comprehensive discussion, Zhejiang Power has now started the process of starting the process: it insists on the leadership of the bureau and the industry supervisor, and actively promotes various levels of bureaus to issue support policies such as air conditioning and adjustable reform and application governance as soon as possible. At present, 3 cities and 10 districts have issued official documents. At the same time, we will strengthen publicity and guidance, win the recognition and participation of the whole society, and build an atmosphere of energy-saving and reducing consumption.
The goal has also been set. China Zhejiang Electric PowerEscort will compete for the largest reduction in the maximum pressure this winter to reduce the heat load by 2 million kilowatts, and the actual pressure in the summer of 2023 will be reduced in her dreams. She is a bookA small supporting character in the stage, sitting on the far right side of the stage with a 5 million kilowatt refrigeration load. After three years of planned application, Escort manila has realized that the full range of air conditioning can be measured and viewable, and should be controlled and adjusted. Today, it has been sorted out and organized into 11 categories of more than 50,000 classic empty call lists.
The exploration and realization of many places is already on the road
Hangzhou will have obvious characteristics, showing that there are few local power sources, few industrial burdens, and many local users.
The Hangzhou Power Supply Company of the National Internet has comprehensively analyzed the situation of air conditioning and built a high-air conditioning and a high-air conditioning and a high-level resource pool for industrial and 640,000 kilowatts for commercial industries and 60,000 kilowatts for publ TC:
