电力现货市场下的数据清算具有数据规模大、业务处理复杂、时效性要求高等特征,为解决现货市场清算系统面临的突出问题,文中提出了基于通用结算数据模型的清算方法。通过建立多维立方体数据模型,实现复杂维度数据的统一建模,再进一步建立算子库,实现模型之间的转换和清算的灵活计算。最后,建立列式数据仓,通过列式计算与列式对比,实现电力交易的高性能清算。根据所提方法研发的软件已应用于省级现货市场试点单位,实际运行证明了其有效性和可靠性。
Data clearing in the electricity spot market has the characteristics of large-scale data
complex business processing and high timeliness requirement. In order to solve the outstanding problems faced by the clearing system in the spot market
this paper proposes a clearing method based on the general settlement data model. Through the establishment of the data model of multidimensional cube
the unified modeling of complex dimensional data is realized
and then the operator base is further established to realize the conversion between models and the flexible calculation of clearing. Finally
the column data warehouse is established
and the high-performance clearing of electricity trading is realized through column calculation and column comparison. The software developed using the proposed method has been applied to the pilot provincial spot market
and the actual operation proves that the method is effective and reliable.
