Problems solved by technology
[0002] With the development of society, the electric power industry is also occupying more and more markets. Similarly, the power grid is also an important means to realize my country's energy strategic layout, an important link in the energy industry chain and an important part of the national comprehensive transportation system. People's attention to the power grid The dependence is also increasing day by day, but due to people's dependence on the power grid and higher demand, the requirements for the power grid are getting higher and higher. Therefore, the power grid needs an optimized operation mode, but in the traditional optimization mode, Only by changing the voltage quality of the power grid and the passing line current, the problem cannot be solved fundamentally, so how to select and optimize the power grid is still a technical problem that people need to work hard to overcome
