对基于历史数据潮流确定策略的实用化进行了研究，针对该方法内存占用量大的缺点进行了改进。提出了对灵敏度阵进行简化的方法。对不同规模IEEE标准测试系统的试算表明：计算精度完全满足工程要求，且系统规模越大，简化效果越明显，在保证精度的前提下，最多可节省内存空间80%。

The research on practicability of load flow determination strategy based on historical data, which has been previously put forward in reference［6］, is carried out. The shortcoming of taking up too much memory space in theabove mentioned method is improved. On the basis of analyzing the sensitivity matrix used in this method in detail, the approach of simplifying the sensitivity matrix is put forward. The results of trial calculations for IEEE test systems of different size show that after processing the sensitivity matrix with presented simplification approach, the calculation accuracy is satisfied. The larger the system size is, the more outstanding the effect of simplification will be. Under the precondition of ensuring the accuracy of the results, more than 80% memory can be saved at best.
