基于集群机组组合的区域电力系统生产模拟仿真

Regional Power System Production Simulation Based on Clustered Unit Commitment

  • 摘要: 在对大规模区域电力系统开展中长期运行分析时,传统基于二进制机组组合的生产模拟仿真方法存在计算规模大和计算效率不高的问题。针对该问题,提出了一种基于集群机组组合的生产模拟仿真方法。该方法忽略区域内部电网模型,将火电机组按照类型和容量相似性在各个子区域进行分类聚合,建立了集群机组组合模型,并采用运输模型近似考虑区域间联络线约束对生产模拟仿真的影响。基于IEEE RTS-96系统的3区域测试系统算例分析,验证了所提方法能够在保证合理计算精度的同时,大幅提高生产模拟仿真的计算效率。

     

    Abstract: Traditional production simulation based on binary unit commitment suffers from huge computation burden and low efficiency in the long-midterm operation evaluation of large-scale regional power system. To address this problem, the paper proposed a production simulation method based on clustered unit commitment, in which the power network model was neglected in subregions, and the units was clustered by their sizes and types in respective subregions. Furthermore, the interconnection between subregions was modeled as a transportation model to roughly evaluate its influences on power system production simulation. The case study of a 3-area system based on IEEE RTS-96 system shows that the proposed approach can significantly improve the computation efficiency while ensuring the accuracy of calculation.
