Future grid data will enter the "cloud" side

With the onset of intense heat, Shencheng hit a peak in electricity usage. Recently, in the Jinqiao area of ​​Pudong, about 700 households were affected. At the beginning of June, Jing'an, Huangpu, and other central districts also suffered large-scale blackouts. A technical seminar on the future development of power grids was held in Zhangjiang recently. Scientists shared an industrial Internet technology at the conference. It will bring the future power grid to the “cloud” side, and the monitoring, management and control of the power grid will be more intelligent. The “precursors” of blackouts, steals, and other diseases are clear at a glance.

Sharp increase in electricity demand

It is estimated that by 2030, electricity demand in Asia alone will double.

Nowadays, the traditional grid is one-way: power plants are concentrated in one place and then delivered to users. Especially in China, energy is mainly concentrated in the northwestern region. Long-distance transmission will also cause losses, and it will easily lead to equipment aging and power outages. Therefore, in order to deal with the loss, our country advocates ultra high pressure engineering. According to Yuan Qingyun, a deputy general manager of the State Grid DC Construction Branch, the State Grid Corporation of China will build up to 20 ultra-high voltage direct current projects by 2020, with a total capacity of 320 million kilowatts, and a total of 37,000 km of DC lines.

Activate "sleeping" data

At the seminar, power grid technology experts agreed that smart grids in the future are ways to reduce accidents such as blackouts. Kang Pengju, director of electrical R&D technology at GE China R&D Center, said that in the future, the grid will enter the “cloud” side with massive amounts of big data. He shared an industrial Internet technology that is currently under development. A software platform will connect each individual power consumer and integrate data from different systems and devices, including current grid management systems, smart meters or other smart grids. Equipment, sensors, weather forecasts and even information from social media to monitor and predict grid faults and equipment life. "For example, we can use Google Maps to analyze vegetation information, avoid large trees that may pose a potential threat to the grid cable during grid erection, etc. Once an equipment accident occurs, intelligent software on the 'cloud' side can help maintenance personnel locate quickly."

Experts revealed that the power system collects massive amounts of information every day, but about 80% of the data is in a state of sleep. According to scientists, if these numbers are all “activated”, the global power grid will systematically optimize its intelligence, and if it reduces energy consumption by 1%, it will save the world $66 billion, of which China can save $8 billion.
