Research on the Trend of Power System Cost Evolution for High Percentage of New Energy Accesses

With the large-scale high proportion of new energy access, the cost structure and characteristics of the power system will change, and the cost of system security will increase substantially. How to accurately measure power system costs is a current challenge that needs to be addressed. Therefore, this paper begins with an analysis of power system costs. Second, a power-side cost prediction method based on learning curves is proposed, a grid cost prediction model considering regression equations is constructed, and the system operation cost is measured by production simulation. Finally, an arithmetic example is analyzed based on the development of Gansu Province, in order to provide a scientific and reasonable mathematical prediction model for the power system under the high proportion of new energy access.
