Abstract

One of the major element contributing to the stability of system voltage is available reactive power so that it is vital that the system operator should always keep track of how much generator reactive power reserves are currently available. Generator reactive power reserve is usually calculated by deducting current available reactive power from the maximum reactive power that can be generated by the generator. Even so, such a calculation alone does not ensure stability of system voltage. Therefore, the sensitivity matrix has been considered in this study. This matrix is useful when identifying the correlations between generator and load buses. The effective reactive power reserve (EQR) can be estimated by using this matrix to achieve voltage stability instead of employing the conventional reactive power reserve (CQR).
