At high temperature, how to achieve "air -conditioning freedom"?Energy insurance is inseparable from meteorological technology!

This year, Hubei Province has experienced

Long -term, large -scale, extreme

Hot weather

Facing the heat of the heat

The province is advocating for electricity consumption

Still guarantee the "freedom of air conditioning" of the people

how did you do that?

The interview group entered the Hubei Provincial Meteorological Bureau

And the province's new energy assembly machine has the number one power generation

In recent years

Hubei Provincial Meteorological Bureau around the "double carbon" goal

Focus on the efficient use of scenery water resources

And energy security and stable supply

Vigorously develop energy and meteorological services

For energy production, transportation, consumption

Provide full chain fine service

Hu Xiaofeng, a level 4 staff member, told the interview group:

""

Until this summer, Huanggang's air -conditioning electricity load has increased from 1 million kilowatts last year to 1.5 million kilowatts. The maximum daily power supply load increased by 18.4%over last year. There is no large -scale power outage of residents. This is inseparable from the meteorological department's early prediction and rolling forecast warning of the weather trend this summer, and it is inseparable from the accurate new energy power generation power, the entire network of electricity loads, and the network supply prediction information.

Huanggang is located in Northeast Hubei in the south of Dabie Mountain in Dabie Mountain

With unique wind, light, landscape, etc.

Natural resource endowment

This is the development of wind power

The prerequisite for photovoltaic and pumping storage projects

at the same time

Huanggang has a broad suitable development of photovoltaic

Land resources and space

Therefore, build a clean and low -carbon energy as the main body

New power system

Become one of the important measures for local energy development

In recent years, driven by the "double carbon" goal, Huanggang's new energy development situation is rapid, and many central enterprises and well -known energy companies have settled in Huanggang. At present, Huanggang has built 18 wind power stations, 6,515 photovoltaic power stations, and 142 hydropower stations. In the first half of this year, the power generation accounted for about 1/4 of the province's power consumption. Therefore, the guarantee of new energy power generation and power grid scheduling is essential to ensure the demand for electricity consumption in the city and the province.

In June of this year, Huanggang Power Supply Company received a climatic trend of the Municipal Meteorological Bureau on the peak of the summer. The municipal power supply company immediately reported to the provincial company and storage of water in the domestic hydropower station in advance. It also reminded the clean energy power plant to complete the equipment maintenance by the end of June to ensure the normal operation in July. Under the next month of high temperature weather, the new energy power supply facilities in Huanggang's area operate safely and efficiently, which has effectively guaranteed residents' electricity.

In mid -July, the Huanggang Power Supply Bureau received a meteorological special report and learned that it will usher in the short cooling weather in the next few days. Inspection, accelerate the maintenance of equipment with hidden dangers in order to deal with another round of continuous high temperature weather that will appear on July 26. Throughout the summer, the power and meteorological department joined hands with the "beautiful battle" of the peak summer power protection!

However, before 2017, due to the complexity of geographical climatic conditions and the intermittent and volatility characteristics of wind and light resources, Huanggang Power Supply Company's load prediction of the same industry benchmarking indicators in the province have been reunited for a long time. Loading forecast is very difficult.

In order to enhance the ability of new energy power and load predictions, and help Huanggang's new energy power generation grid to connect the efficient use of the grid, the meteorological department of Hubei Province takes Huanggang as the pilot to develop and build the nation's first comprehensive energy meteorological service platform -Huanggang's electric power intelligent dispatch meteorological service Decision support system.

Senior engineer Xu Peihua introduced:

""

We have comprehensively adopted technologies such as big data, deep learning, and GIS to build a power generation power prediction, electric load prediction, network supply prediction method and model mainly based on meteorological elements. Power generation power, electric load, network supply intelligent prediction system, providing technical support for the dispatching operation decision -making decision -making decision -making decision -making decision -making decision -making, the coordinated control of the network source load storage, and the balance of power and power planning.

From October last year

The system is launched on trial operation

And access to Huanggang Power Supply Company Dispatching Control Center

Replace the power grid dispatch on duty staff

About 80%of the workload every day

Hu Xiaofeng introduced:

""

This system not only predicts the power generation power of new energy in the next 10 days, but also gives super short-term power forecasts within the next 4 hours. The dispatcher has grasped the new energy power plant in advance. Wise situations, and accurately control mistakes and avoid peak power supply capabilities. From January to June 2022, the average daily accuracy of the short-term prediction of photovoltaic power generation in Huanggang Power Grid reached 94.5%, the average daily accuracy rate of the short-term forecast of wind power reached 90.35%, and the daily maximum load prediction daily accuracy was 97.08%, which was effective to maximize the use of new new exposures. Energy power has played an important role.

"

In addition to accurately predicting power generation power and power load, the Meteorological Department of Hubei Province also developed a forecast and early warning service product including wind turbine ice, continuous low wind, and rainy days for wind power facilities, and through intelligent dispatching meteorological service decision -making support systems through intelligent dispatch meteorological service decision -making support systems Real -time push to the power department to take effective measures in advance to ensure power generation and electricity balance.

This year, Huanggang's new energy installation capacity increased by 1.7 million kilowatts compared with last year. Behind the continuous power generation capacity, it is the gradual expansion of the wind power station network layout. The provincial and municipal meteorological departments and power companies have strengthened cooperation, focus on the development and utilization of climate resources, and jointly strengthen the wind field, the macro -micro site selection of photovoltaic power stations, and resource evaluation. The meteorological department provides climate background analysis and evaluation for the scientific layout of the power department of the power department, helps clean energy development and use, and contribute meteorological wisdom to the province to achieve the "double carbon" goal!
