Mathematical Formulation of Voltage Stability: Mathematical Formulation of Voltage Stability - The slower forms of voltage instability are normally analyzed as steady state problems using power flow simulation as the primary study method. "Snapshots" in…
Voltage Stability in Power System: Voltage Stability in Power System - Voltage control and stability problems are very much familiar to the electric utility industry but are now receiving special attention by every power system…
Long Term Load Forecasting in Power System: Long Term Load Forecasting - If the load forecasts are required for planning purposes, it is necessary to select the lead time to lie in the range of…
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…
Time Series Forecasting Methods: 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)…
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…
Estimation of Trend Analysis in Load Forecasting: Estimation of Trend Analysis in Load Forecasting - The simplest possible form of the deterministic part of y(k) is given by where y̅d represents the average or the mean…
Types of Forecasting Methods: Types of Forecasting Methods may be divided into three broad classes. Techniques may be based on extrapolation or on correlation or on a combination of both. Techniques may be further classified…
What is Load Forecasting in Power System?: Load Forecasting in Power System plays an important role in power system planning, operation and control. Forecasting means estimating active load at various load buses ahead of actual…
Types of Facts Controllers in Power System: The development of FACTS controllers has followed two different approaches. The first approach employs reactive impedances or a tap changing transformer with thyristor switches as controlled elements, the…
