An expert system for load flow planning

Abstract

A sensitivity based Intelligent Load Flow Planning Engine is developed. The main objective of the engine is to provide both an expert and novice user with a friendly working environment, aiming at enhancing a user's creativity in making operational plans in power system. The developed engine can review the initial load flow results, detect abnormals and suggest necessary control measures to alleviate line overloads and adjust the load bus voltage, var generation and voltage angle of generator bus to desired operating limits. The expert system is developed using Expert System tool called CLIPS based on rule-based method and forward chaining reasoning process. Simulation studies with the developed expert system applied to various power systems show satisfactory results.
