Coordinated confession

Strengthen cross -regional transaction linkage

This summer, under the premise of the reliable supply of electricity in the guarantee area, the Huazhong Power Grid regards the stable supply of cross -regional transactions as a key factor in ensuring power supply. Compared with the same period last year, from January to May this year, the cross -zone of Huazhong Power Grid has increased significantly, and the transaction power between the provinces is extremely active, and the proportion of electricity consumption in the China -China Power Grid Cross -region's power in the China Grid has shown an increase in electricity. From January to May, the largest power of China and China ’s largest electricity accounted for 21.6%of the maximum load of China China Power Grid. According to predictions, from July to August, the largest electricity to China cross -district and province will account for 21%of the maximum electricity load of China China Power Grid; the transmission of China CCCPCC will account for 22.5%of the power consumption of the China China Power Grid.

The Central Branch of the China State Grid Co., Ltd. paid attention to the changes in the data of cross -regional transmission volume in time, innovated the cross -regional transaction mechanism, and proposed that "DC Points province prioritize and takes into account other provinces' power purchase needs" Multiple provinces have "" multi -channel joint optimization "and other trading ideas to strengthen the role and platform value of the region in the resource optimization allocation, and play an important role in complementary resources, mutual benefit from the Internet, and market reciprocity.

Carefully scheduling

Safe reliable power supply under large load

At 11 am on June 24th, the main transformer No. 1 and 2 of Nanjing 220 kV Shanjiang transformer station in Nanjing, Jiangsu appeared heavy loads. Liu Ling, a dispatcher of the Electric Power Schedule and Control Center of Nanjing Power Supply Company in Jiangsu, immediately contacted the 10 kV load of the Shanjiang Transformer Power Station of Nanjing Jiangbei New District Company's Electricity Schedule and Control Sub -Center.

As the temperature rises, the load of the scheduling of Nanjing Grid has continued to rise. In this regard, Nanjing Power Supply Company closely followed the weather, rolling the grid load prediction, analysis of the weakness of the power grid, and accidental expectations, strengthened the communication report with government departments, scientifically formulated the power grid operation guarantee scheme, so as to carefully dispatch, carefully command, and carefully operate. , Ensure the safe and stable operation of the power grid, and ensure the power consumption of people's livelihood and public business. On June 17, Jiangsu Power Grid scheduling the highest -use power load for the first time this summer exceeded 100 million kilowatts and reached 103.6 billion kilowatts. Compared with the first 1921 load in 2021, it took 19 days in advance. Faced with high temperature and high load challenges, State Grid Jiangsu Electric Power Co., Ltd. adheres to the peak summer power protection, strictly implement the 30 work points of the National Power Network to welcomes the peak summer power, carefully organize, refine measures, and strive for full effort Promote.
