Analysis on the Acceptance Capacity of Nuclear Power Integrated with Northwest Power Grid Based on Power Balance

Based on an analysis of the load characteristics of the northwest power grid,especialy its peak and valley values, this paper calculates the grid's acceptance capacity of nuclear power in 2020,2025 and 2030,respectively,based on electric power balancing.It also analyzes the impacts of the large-scaled wind power development on the acceptance capacity of nuclear power. The results show that the ability to accept nuclear power to the grid is closely related to the scale and progress of wind power development in the regioa Without wind power,the grid can accept 26 000～48 500 MW of nuclear power from 2020 to 2030.However, with all the wind power generated in the region entirely integrated in the grid,the grid has no load peaking capacity for nuclear power in 2020;whereas it has only 12 000 MW load peaking capacity for nuclear power in 2030.
