A Multi-Source Dispatching Model with Considering the Nuclear Power Plants Dispatching and Wind Power Accommodation

摘要

With the large number of volatile renewable energy sources such as wind power being connected to the grid, the traditional power operation scheduling method has been unable to meet the consumption demand of renewable energy. Firstly the paper comprehensively considers the traditional nuclear power operation mode and wind power output characteristics, adopts the fixed peak depth, uses the Pearson correlation coefficient to match the nuclear power and wind power output during the pre-dispatch period and determine the optimal nuclear power operation mode. Secondly, on the basis of not changing the base load characteristics of nuclear power and considering its safety and economy, a nuclear power peak shaving operation model suitable for coordinating wind power consumption has been established, and the particle swarm algorithm is used to realize the coordinated and optimized dispatch of multi-source. The paper selects data from northern China to verify that the proposed optimized operation method can increase the proportion of wind power consumption, improve economy and ease the pressure of peak shaving.
