Research on Comprehensive Evaluation Model of Power System Priority Scheduling with Large-scale New Energy Considering Multi-base and UHVDC Transmission

The wind power and photovoltaic power generation is developing rapidly in China, but there are also serious problems of wind power and solar abandonment[1]. In order to promote the consumption of new energy and fully realize the environmental benefits and social benefits brought by the new energy power generation, it is very important to conduct the scientific and rational evaluation of the power system priority scheduling with large-scale new energy[2]. The paper first establishes a new energy priority scheduling evaluation index system based on the multi-base and UHVDC transmission factors and builds a comprehensive evaluation model of power system priority scheduling with large-scale new energy sources[3-5]. Finally, the comprehensive evaluation model[68] is used to evaluate the new energy priority scheduling effect in three scenarios according to the actual operation data of the new energy in grids in a region of China.
