Summary: | This paper puts forth a closer look into the impact of having multiple outliers in the historical data, which are fed to the Grey Prediction Model named GM(1,1) for the purpose of predicting the value of current missing datum. The mentioned miss is majorly caused by sudden, momentary and unforeseen failures of measuring as well as telemetering equipment. Once the predicted datum is ready, it is able to aid the State Estimation (SE) of Power System. Weighted Least Squares (WLS) method is applied here as the SE technique. |
