Abstract：The Central China power grid has now formed a special ultra-high voltage"日"-shaped ring network,with close connections among the four provincial power grids.However,market mechanisms remain underdeveloped with suboptimal usage of inter-provincial tie lines,indicating significant potential for enhanced resource distribution.This study,with a focus on regional market construction benefits,firstly identifies challenges to the supply-demand equilibrium within the four provinces.Benefits of the Central China regional electricity market are then qualitatively assessed concerning generation costs,renewable energy integration,and system reserve requirements.Utilizing actual data from 2021,a simplified model for the Central China regional electricity spot market is constructed for quantitative analysis.Post-market establishment benefits and their distribution are examined.An anticipated 70％increase in the utilization rate of inter-provincial tie lines could result in a yearly saving of approximately 4.7 billion yuan in generation costs network-wide.This includes a 2.1 billion yuan increase in generation side profits,an additional 1.1 billion yuan in grid side inter-provincial transmission fees,and a 1.5 billion yuan decrease in user-side electricity costs.
