Long Term Load Prediction

Long Term Load Prediction Using Econometric Models: Long Term Load Prediction – If the load forecasts are required for planning purposes, it is necessary to select the lead time to lie in the range of a few months to a few years. In such cases, the load demand should be decomposed in a manner that […]

Kalman Filtering Approach

Kalman Filtering Approach: Kalman Filtering Approach – The time series approach has been widely employed in dealing with the load forecasting problem in view of the relative simplicity of the model forms. However, this method tends to ignore the statistical information about the load data which may often be available and may lead to improved […]

Estimation of Time Series Prediction

Estimation of Time Series Prediction: Estimation of Time Series Prediction – If yd(k) is subtracted from the sequence y(k), the result would be a sequence of data for the stochastic part of the load. We have to identify the model for ys (k) and then use it to make the prediction ys(k+j). A convenient method […]

Estimation Techniques of Periodic Components

Estimation Techniques of Periodic Components: Estimation Techniques of Periodic Components — The deterministic part of the load may contain some periodic components in addition to the average and the polynomial terms. Consider for example the curve shown in Fig. 16.2 which gives the variation of the active power supplied by a power utility over a […]
