China's largest "virtual power plant" is used

The virtual power plant, also known as the “energy efficient power plant”, generates “excess” energy by reducing the power demand of the terminal electrical equipment and devices. Because the reduction in demand is equal to the increase of the power supply to other parts of the power grid, it is equivalent to the construction. Actual power plant. On May 24th, China's 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 the "balances" that are constantly changing on both sides achieve instantaneous balance.

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.

According to relevant sources, through this “source network-loaded smart grid” system, the grid is not only connected to the user by a main line, but extends to each user's electrical equipment, making a large number of decentralized and uncontrollable power equipment, transforming A controllable resource of the millisecond level. It is reported that the system has been piloted and promoted by 1,370 enterprise users, and the power capacity that can be cut off at any time without affecting 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 to other people. use. It is equivalent to building a “virtual power plant”.

Moreover, this system can be divided into a production of 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.

It is understood that the "source network and smart grid" system is about to begin to 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.
