The third-generation grid will become a large-scale new energy power transmission network

A few days ago, Zhou Xiaoxin, academician of the Chinese Academy of Sciences, and his entourage came to the 100,000-kilowatt revitalized photovoltaic power station in Linze Town, Yangzhou City
.
During the Spring Festival, the photovoltaic power station took the lead in China to carry out the technical exploration
of sending reactive power from the inverter group of the photovoltaic power plant to the extremely light-load power grid to improve the power supply quality of the power grid in the way of "grid-source interaction".
During the research and inspection, Zhou Xiaoxin was interviewed
by the media.

Media: You put forward the concept of "third-generation power grid", how to divide the generation, and what is the meaning of the third generation?

Zhou Xiaoxin: If you want to divide the development of China's power grid, the first generation of power grid refers to the power grid characterized by small units, low voltage, and isolated power grid, and China's power grid in the fifties and sixties of the last century is almost at this stage
.
The second-generation power grid is a stage of large-scale development of power grids characterized by large units, ultra-high voltage, and interconnected large power
grids that have developed rapidly since the reform and opening up.

It should be noted that the second-generation grid is built on fossil energy and is not sustainable
.

The most significant feature of the third-generation power grid is that large-scale new and renewable energy accounts for more than 60% of the grid! In the face of global climate, environmental change and the pressure of the depletion of fossil energy, the new energy revolution is quietly rising, in China's coal-based energy structure transformation, one of the important missions of the third generation of power grid is to become a large-scale new energy power transmission network
