On October 18th, in the classroom of Zhejiang Yuexiu Foreign Languages University, the staff of State Grid Shaoxing Power Supply Company installed load control devices for each air conditioner one by one, and the 3,800 kW air conditioning load of the university was officially connected to the power "non-responsive" platform. On the same morning, in the headquarters building of the branch of China Unicom Zhuji City, 20 sets of air conditioning loads of more than 60 kilowatts were also included in this platform, becoming the first batch of "science and technology power saving" air conditioning in Zhuji City.
"This summer, the highest social cooling load of our city, mainly air conditioning, is about 2.7 million kilowatts, accounting for 31 percent of the highest social load. There is a lot of room for energy saving in air conditioning." With its power supply company shaoxing camp zi-jian guo tells a reporter, deputy director of the safety technology center after a statistical study found that the zhuhai power users to set common air conditioning temperature does not meet the national advocacy of 26 ℃, 20 ℃ in winter "summer" requirements, and to adjust the temperature to the requirements of the process, perception of the body is not obvious, this is also called "non-inductive regulation".
To this end, State Grid Shaoxing Power Supply Company established a power "non-sensitive response" platform. After active communication with government units, enterprises, merchants and other users, the air conditioning load was connected to the control platform with 5G quantum encryption communication technology to realize the security perception and accurate control of air conditioning load resources. When the power resources are tight, the power supply company sets the air conditioner to be insensitive (26 ° C in summer and 20 ° C in winter) or light sensitive (28 ° C in summer and 18 ° C in winter) through the control platform, so as to use the electricity saved from the air conditioner to protect the people's livelihood and other important areas of electricity consumption, and ensure the stable and orderly operation of the economy and society.
According to the calculation, when the air conditioning refrigeration operation, every 1℃ increase in the temperature setting, the average reduction of electricity load about 7% ~ 8%; When the air conditioner is running for heating, the electricity load decreases by about 6% on average for every 1 ° C decrease in the temperature setting. "The non-responsive response can effectively save resources and reduce our electricity bill by 20 percent. It is a good thing for the country, people and enterprises. We should actively participate in it." China Unicom Zhuji branch business director Chen Hao said.
State Grid Shaoxing Power Supply Company plans to successively connect air conditioning load to the management platform before the end of the year to effectively save power resources by scientific and technological means. At the same time, other large power facilities such as cloud energy storage, charging pile and smart street lamp are upgraded and connected to the "non-inductive response" platform simultaneously, so as to promote the extension of load control to multiple categories and dig deep energy saving space.
Up to now, the State Grid Shaoxing Power Supply Company has completed the installation of more than 3,000 air-conditioning control terminals, with a total rated power of about 20,000 kW and a load adjustment of 4,000 kW. It is expected that 120,000 kW will be connected before the end of this year and 200,000 kW will be connected before the peak summer next year. In addition, the "non-inductive response" platform has simultaneously connected to Wolong Energy Storage, Xinchang Optical storage and charging integration, dual photovoltaic + energy storage and other users, involving more than 400 DC charging piles and more than 2,000 smart street lamps.
