A Novel Method for Siting and Sizing of IPP for Improved System Stability/Security

This paper presents the technical and economic impacts on the transmission system due to the presence of the new production sources i.e. independent power producers (IPP). An approach is presented for selecting a suitable location of new generating plant (IPP) so as to increase system stability/security and the loss reduction under normal operation and network contingency conditions. The proposed approach uses the re-dispatching generation (RDG) factors as indicators to change the generation levels so that more power can be transferred before reaching a boundary of a critical limit such as the voltage collapse boundary. The method has been tested under simulated conditions on several systems and results are presented for a real-life 24-bus equivalent EHV system.
