Application of electrical engineering in green development and environmental protection from the perspective of new normal.

Under the new economic background, the new normal characteristics of China's power development are also obvious, highlighting the slowdown in the growth of electricity consumption in the whole society, the overall downturn in power consumption in high energy consumption industry, the continuous optimization of power structure, and the more obvious regional differences. In view of these problems, this paper analyzes the economic and stability of the power grid and the constraints of the power grid stability and the transmission capacity of the transmission section, and constructs the economic consideration with the minimum purchase cost and the minimum discharge amount of the pollutant gas as the objective function. And the particle swarm optimization algorithm is used to solve the problem. In this paper, an example is given to calculate and analyze the actual grid, and the validity and feasibility of the model are verified. [ABSTRACT FROM AUTHOR]
