Henan Power Grid "Welcome Summer" came to an end, and the "peak period" occurred on this day

Elephant News · Dongfang today's chief reporter Liang Xinhui correspondent Huo Xin

The autumn is here, but the scene where the load is constantly rising in midsummer is still disturbing. Affected by factors such as sustainable high temperature weather, the growth of industrial economic recovery, and the significant reduction of water and electricity in the south, this year's summer insurance supply is particularly special and particularly difficult compared to previous years. The peak of electricity load comes early, the length of continued, and the increase is unprecedented. The province's electricity load hit a high in June three, and it hit the high in August.

On September 28, Elephant Journalists learned from the State Grid Henan Electric Power Company: After continuous efforts and taking multiple measures, the "Welcome Summer" in 2022 ended smoothly, ensuring the light and coolness of more than 43 million users in the province in the province. Essence This summer, the province's highest use of electricity load, and finally set the 77.92 million kilowatts on August 5, an increase of 14.3%from the historical maximum value.

Invest in 43 main networks on schedule to welcome the peak summer project

Ensuring power supply, conventional power support is the key.

Before the beginning of Duxia, Henan Electric Power put forward 43 main networks to the peak summer project on schedule, which improved the overall power supply capacity of Henan Grid 2 million kilowatts, and consolidated the foundation for alleviating the pressure of high temperature in summer.

Henan Electric Power adheres to systemic thinking, and carefully carried out the combined optimization scheduling of electricity and coal and the peak capability test of the unit. 67%of the province's conventional power source installation machines bear more than 80%of its peak power, effectively responding to the severe situation of extremely heat, light peaks, and extremely low power of new energy units, and stabilized the "basic disk of power guarantee to protect the supply of power supply. "".

In mid -June, Henan ushered in the first round of high temperature weather this year. The maximum temperature in many places in the province exceeded 39 degrees Celsius, and the load with electricity rose rapidly. Henan Electric Power fully launched the Peak Summer Safety Supply for the "Dight -duty" operation mode. The first time the high temperature level III emergency response was released, more than 59,000 professional employees were waiting for it, and the entire army attacked.

Facing the power load that has reached a record high, during the summer of this year, the State Grid Henan Electric Power optimized and adjusted 21 provincial network operation methods in a timely manner to improve the power supply capacity of 3.2 million kilowatts; the creative implementation of Lingbao DC delivery, maximizing the power supply capacity of Henan South China 1.8 million kilowatts effectively guaranteed the safe and reliable supply of power.

The scale of external electricity enters Yuyu 38 days exceeds 10 million kilowatts

On September 19th, the 1,000 -kV high -voltage exchange project (Henan section) of Zhumadian — Wuhan 1,000 kV high -voltage exchange project (Henan section) was completed, marking the successful completion of the project and officially entered the group tower stage.

As an important part of the "Japan" glyph -shaped high -voltage AC power grid, the project will effectively improve the ability to optimize the allocation of resources in Henan Power Grid after completion, and play an important role in ensuring the safe and reliable supply of electricity.

Henan Power Grid is located in the hub of the north -south mutual supply and the nationwide network. In recent years, it has successively built a high -voltage "5 stations and 13 lines". Facing the peak of the peak summer load, Henan Power Power pays close attention to the situation of power supply and demand, based on the actual advance and judgment, comprehensively strengthen the reporting and communication, make full use of the mid -to -long -term and spot markets of the provincial provincial, and strive to strive for foreign power support.

According to statistics, during the peak summer this year, the scale of foreign electricity entered the high 38 days exceeded 10 million kilowatts, up to 14.61 million kilowatts, accounting for nearly one -fifth of the province's electricity load. Especially at the peak time, in the case of the comprehensive tension of power supply and demand in the country, the urgent purchase of 796 million kilowatt -hours of foreign electricity has played an important role in alleviating the contradiction between supply and demand during the peak period.

Henan Power Grid spent the final "peak period" smoothly

At the time of the high temperature and power supply supply, Henan Power has always adheres to the bottom line of the use of the electricity of the people, and tries everything to ensure the safety and reliability of the people in the province. Among them, the reliability of load demand side management is very important.

Faced with the continuous rising power load, Henan Electric Power adheres to demand response priority, relying on the power meteorological service system to accurately predict the supply and demand situation, and timely issue 4 power and electricity balance warnings in time. In the same way, actively excavate and scientific scheduling can interrupt load resources, use market -oriented methods to guide users to participate in demand response, and comprehensively strengthen the application of demand -side management methods.

At the same time, the State Grid Henan Electric Power vigorously carried out energy efficiency improvement and intelligent energy work, and created a batch of energy -saving and effective demonstration projects around public building energy custody and energy saving carbon reduction and carbon reduction. Running and power supply is smooth and orderly.

This summer, the province's highest use of electricity load, and finally set at 77.92 million kilowatts on August 5, an increase of 14.3%from the historical maximum value. After continuous efforts, Henan Power Grid has stabilized the final "peak period", and the peak summer came to an end.
