Research on Initial Power Flow Calculation Automatically for Dispatcher Training Based on Grey Correlation Analysis

针对交直流大电网调度培训仿真领域满足特定需求的运行方式调整工作量大、周期长、人工干预多的问题，提出基于灰色关联分析法的大电网调度培训基态潮流自动生成方法。定性分析了交直流大电网运行方式影响因素，划分为时间、气象、电网运行数据特征量三个维度；利用灰色关联分析法提出了运行方式综合相似度判据定量计算方法，并建立了相似日运行方式逐级筛选规则。以某实际电网为例，验证了方法的合理性、有效性。
For problems of adjusting target power flow of power grid in dispatcher training simulation field, such as heavy workload, long time, a lot of human intervention and so on, propose a method of automatic adjustment of the initial power flow of the large power grid dispatch training based on the gray correlation analysis. Qualitative analysis of the influence factors of the operation mode of the large power grid, divided into three dimensions: time, weather and power grid operation characteristics. The gray correlation analysis method was used to calculate the comprehensive similarity, and established a similar daily operation of the step-by-step screening rules. Taking an actual power grid as an example, the rationality and validity of the method were verified.
