Abstract

The bus power balance is an important index to quantify the power system basic data. In view of the current shortage of power imbalance evaluation at single time section, in this paper, imbalanced power is regarded as a normal distributed random variable and the its historical data is statistically analyzed. This method takes the sample median as the estimate of the population mean, confidence interval of sample standard deviation as the interval estimation of population standard deviation, reflecting the distribution of bus imbalanced power. An example on actual stations is given in this paper, the power system basic data are quantified from the perspective of statistics.
