The main reason for the birth of the smart grid is to strengthen the internal linkage of power resources in the country. In the final analysis, due to the urgent need for energy development, domestic project construction is gradually accelerating. Our territory has a vast territory and directly increases the difficulty of building energy systems. The concept of smart grid is proposed, at least in the concept of a unified national grid system can be a unified linkage. With the increasing use of renewable energy, distributed energy is ushering in opportunities for development. Insiders pointed out that at the transmission and distribution end, the smart grid as its supporting foundation is the future direction of power grid development. According to company sources such as the State Grid Corporation of China and the Huadian Group, the power system is closely following the trend of distributed energy development and is pushing for smart grid construction and distributed generation. Zhang Guobao, director of the National Energy Commission’s expert advisory committee and former director of the National Energy Administration, pointed out at the forum that the smart grid, like the Internet, can respond to the ever-changing energy supply situation. “So far there has been controversy over whether solar energy and wind power are controllable. The problem of abandoning wind, abandoning electricity, and abandoning water is the problem that the network is not smart enough and sound enough.†Chongqing Xingjida Import and Export Trade Co., Ltd. , https://www.xjdvalve.com
