Today, the first “source network-loaded smart grid†system for large-scale consumption of clean energy was put into operation in Jiangsu. Its commissioning is equivalent to having the largest “virtual power plant†in China.
This "source network-loaded smart grid" system is an intelligent technology that can regulate the power generation of power plants while regulating the power consumption of users, so that both sides can constantly change the "balanced" to instantaneous balance.
The electricity we use is instantaneously balanced, that is, how much you use, how much power the plant will send. Like a balance, one end is the user, one end is the power plant, and the bracket that balances it is the grid. Once unbalanced, the grid will have a large area.
The user's electricity consumption is constantly changing. To maintain balance, it is enough to adjust the power generated by the power plant. In the past, most of the power plants were coal-fired power and hydropower, which were convenient for regulation and control. With the addition of uncontrollable new energy sources such as wind power and photovoltaics, the power plant has also begun to change.
Luo Jianyu, deputy director of the State Grid Jiangsu Electric Power Control and Control Center: Through this system, the grid is not only connected to the user by a main line, but extends to each user's electrical equipment, causing a large number of decentralized uncontrolled power equipment to be converted into milliseconds. Level of controllable resources.
Nowadays, this system can divide the electrical equipment of an enterprise into production electricity, office electricity and domestic electricity. Even lighting, air conditioning, etc. can be controlled in real time. Once there is a problem with the power supply, you can do a business. The electricity used for production and office is not stopped. Some lighting is interrupted and the air conditioner is turned up a few degrees instead of the previous one-size-fits-all. power failure.
Now, 1,370 enterprise users have been piloted to promote this system. The power capacity that can be cut off at any time and does not affect the normal production and life of the enterprise has reached 3.76 million kilowatts. That is to say, these powers can be released at any time for use by others. It is equivalent to a "virtual power plant."
It is understood that this system will soon be promoted nationwide. It is estimated that by 2020, the national scale will reach 100 million kilowatts, equivalent to the construction of 100 million kilowatt-class coal-fired units. At the same time, it can also consume more than 100 million kilowatts of clean energy.
