The heavy snow has just passed,Liu Feng, head of the Aogit mushroom factory in Lankao County, Henan ProvinceEagerly came to the county's "big electricity consumer" Aogit Mushroom Factory, and investigated the hidden dangers of electricity consumption through the monitoring of terminal power facilities.
Now the temperature, humidity and nitrogen dioxide required for growing mushrooms are all controlled by this device, so the power outage time can only support two hours at most, once the electricity is overloaded and the power outage is too long, the temperature and nitrogen dioxide concentration of the mushroom room will rise, which will cause the mushrooms to turn yellow and the quality to deteriorate. Liu Feng said.
Aujit Mushroom FactoryAs a key poverty alleviation enterprise in Lankao County, its output and output value are related to the quality of the county's economic and people's livelihood development. In order to improve the planting capacity, Lankao County has completed the "big test" in terms of electricity consumption - maximizing the utilization rate of new energy, formulating the optimal electricity consumption strategy with the help of intelligent monitoring terminals and energy Internet platforms, greatly reducing electricity costs, increasing mushroom production capacity, and benefiting farmers and people.
Behind this, how does Lankao County do it?
Lankao County, Henan Province is a national commercial grain base county, rich in products, and has superior conditions for the development of renewable resources such as wind and light. In July 2018, the National Energy Administration approved Lankao to become the country's first pilot county for rural energy revolution construction. Since then, it has opened the prelude to the construction of new energy such as wind and light in Lankao.
Unlike thermal power generation, new energy power generation depends on the weather for food, and it is difficult to match the demand for electricity. ”Wang Honglin, deputy general manager of Lankao County Power Supply CompanyIn order to cut the peak and fill the valley and match people's electricity demand, it is necessary to continue to invest in a large number of expensive energy storage equipment to participate in electricity regulation; At the same time, unstable power generation has also had a huge impact on the safe and stable operation of rural power grids.
How to make the grid adjustable? Wang Honglin said with a smile: ".Tame the unstable wind and light
Therefore, starting in 2020, Lankao County Power Supply Company, State Grid Henan Electric Power, and HUAWEI CLOUD have jointly built an energy Internet platform that can be monitored, controlled, and controlled.On the Lankao County Energy Internet Platform, in order to more intuitively observe and record the power generation and consumption data in the county, it is necessary to interconnect the power generation end, power grid, load, energy storage and other equipment on the power grid path. In this link, the most challenging thing is the data collection of distributed new energy power generation equipment.This initiative also explores an efficient and feasible "cloud" smart road for industrial innovation to develop new energy at the county level.
On the one hand, due to the dispersion of distributed equipment such as wind power plants, photovoltaic power stations and rooftop photovoltaics, each photovoltaic power station or wind power plant involves thousands of solar panels or dozens of wind turbine terminals, and even needs to "take the roof as a unit" to fight separately, which puts forward higher requirements for data collection.
On the other hand, in the face of highly volatile new energy terminals, in order to make the most real-time and accurate performance, the latency of data collection must reach the demanding millisecond level.
If you want to get gold from the data "gold mine", you must first solve this problem. In this regard, State Grid Henan Electric Power and HUAWEI CLOUD have used algorithms and control technologies to accurately calculate the power balance of photovoltaic and wind power new energy sources, provide strategies for grid regulation, ensure the safe and stable access of new energy power generation to the power grid, and make it possible to apply new energy power generation on a large scale.
Specifically, at the data access and collection level, State Grid Henan Electric Power has built a next-generation digital system using the data middle platform and Internet of Things provided by HUAWEI CLOUD Stack, and the cloud-edge collaboration capability of HUAWEI CLOUD Stack supports minute-level data collection and data sharing at the perception layer, platform layer, and application layerThe average latency is less than 100 ms
In addition, the intelligent data lake provided by HUAWEI CLOUD Stack can achieve power composite dataSecond-level lake entry and second-level real-time analysisto build a more accurate composite model to accurately generate electricity from clean energy.
The large-scale use of new energy for power generation has always been a world-class problem, and every link needs to be reconstructed. This time, to maximize the participation of new energy sources in the regulation of electricity, Lankao has done it.
Digitalization based on the cloud has become an inevitable choice for the transformation and upgrading of the energy industry. ”Shang Haifeng, President of Huawei Hybrid Cloud"HUAWEI CLOUD Stack advocates the full adoption of cloud-native technologies to help the energy industry accelerate its move towards deep cloud use, realize the digitalization of energy, and promote the energy revolution. ”
Based on the intelligent data lake solution provided by HUAWEI CLOUD stack, State Grid Henan Electric Power assisted in building a collaborative control platform for source-grid, load, and storage, supported the optimization strategy of new energy power dispatching, and accurately generated clean energy power with a short-term accuracy of 965%, far exceeding the international standard of the same kind.Today, Lankao county has 128 installed renewable energy generation capacity90,000 kilowatts, an increase of 31 times over 2016. With the completion of the Lankao Energy Internet Platform, the county's renewable energy power generation has also increased from 21% to 97% of the total electricity consumption of the whole society7%。
Our next step is to build a digital, fully intelligent distribution network in Lankao to further realize the rural energy revolution. Wang Honglin looked at the rows of delicate little mushrooms, his eyes full of hope.
Rural revitalization, electricity first. By working with HUAWEI CLOUD, Lankao County has relied on accurate "elastic" electricity consumption, adding "smart" colors to mushroom cultivation, presenting a "rich scene" of stable production and income increase. With electricity as the medium, the gorgeous butterfly change of Lankao State Grid is also the entropy change of State Grid Henan Electric Power, which makes it possible to apply new energy power generation on a large scale, and also explores an efficient and feasible "Lankao model" for industrial innovation, which has become a strong stroke in China's energy development process.
