Analysis of Reactive Power Demand Based on Voltage-Reactive Power Correlation

A Nonlinear Voltage Stability Index based on Vector Analysis Method and Measurements of Active and Reactive Powers of Power System

This paper proposes a new voltage stability assessment method based on vector analysis method. This index extraction process relies on measurements of active and reactive powers from connected buses to the generator buses. Therefore, a limit for beginning of voltage collapse is determined based on the maximum power transfer theory. On the other hand, when the system requires load shedding, a ne...

Reactive Power Control Scheme Based On Correlation Coefficients for Voltage and Current Signals

.Abstract: In modern digital protection and control systems, a correlation technique has recently become the workhorse of quantitative research and analysis. In this paper, a correlation technique is developed for calculation of original power factor on-line, active and compensation reactive powers and determination of the required number of capacitor banks to get the desired power factor. Cros...

Impact of Demand Response Technique on Hybrid Transmission expansion planning and Reactive Power planning

In this paper, a model for hybrid transmission expansion planning (TEP) and reactive power planning (RPP) considering demand response (DR) model has been presented. In this study RPP considered by TEP for its effects on lines capacity and reduction of system expansion costs. On the other hand the expansion of the transmission system is an important subject, especially dealing with the new i...
