电力市场化改革要求市场公平、平等地对待各市场主体。电力调度公平性是市场公平对待各发电厂的重要部分。电力调度公平性可以通过电量计划完成率反映。反映电量计划完成率差异的主要指标为基尼系数与标准方差。基于2006～2008年度华北区域“三公”调度的数据,通过基尼系数与标准方差对电量计划完成率进行了分析,并取得电量计划完成率的基尼系数与标准方差数据,进行了两者的公平性表征能力相关性及差异性对比分析。通过两者的相关性系数得出基尼系数与标准方差在反映调度公平性上结论一致,数据归一化处理后图形显示标准方差对调度公平性数据对比分析时差异性反映能力更强,而基尼系数对调度公平性数据反映更直观。
Market-oriented electricity reform requires the market to be fair and equal to all market players. The fairness of power dispatching is an important part of the fair treatment of power plants in the market. The fairness of power dispatching can be reflected by the completion plan of power plan. The main indicators that reflect the difference between the completion rates of electricity plans are the Gini coefficient and standard deviation. Based on the data of dispatching in North China region from 2006 to 2008, the completion rate of power plan was analyzed by Gini coefficient and standard deviation, and the Gini coefficient and standard deviation data of power plan completion rate were obtained. Correlation Analysis on the Relevance and Difference of Fairness Representation Ability. Through the correlation coefficient between the two, it is concluded that the Gini coefficient and the standard deviation are consistent in reflecting the fairness of the schedule. The standardized variance after the data normalization shows a stronger ability to reflect the differences in dispatching fairness data while the Gini The coefficient reflects the fairness of the dispatch data more intuitively.
