An intelligent load shedding approach to enhance the voltage stability of a power system
The objective of this dissertation is to perform an exhaustive study of the areas of load shedding and load management and recommend techniques for improvement (for the voltage problem). Two main accomplishments are presented. They are: (1) Expert Load Shedding (ELS), an intelligent operator's aid to help in load shedding is the result of the study of current load shedding practices, and intelligent methodologies. The method suggested in this document has been designed for implementation in an Energy management System (EMS) environment. A prototype of the ELS has been implemented in the Dispatcher Training Simulator (DTS) which simulates an EMS environment. Preliminary results of tests performed using the ELS on an enhanced version of the New-England 345-kV system has proved very promising. (2) Expert Load Management (ELM) is an expert system which has been used to provide load relief (in a distribution system) in an emergency mode. Load Management (LM) is an application in the Distribution Automation (DA) system which involves the process of controlling utility system loads by the remote control of individual customer loads. This expert system has been implemented in the EMS/DA environment and tested on the ODEC (Old Dominion Electric Cooperative) system. Preliminary results of the test performed have proved very promising. The main reason for the development of ELS and ELM are to enable the eventual linking of the two functions. It is the author's contention that a link between load shedding in the EMS and load management in the DA would be possible to obtain load relief without actually tripping feeders.
