Voltage and Reactive Power Control in Power Systems by Genetic Algorithm Considering System Decomposition and Control Process

摘要

This paper presents a new approach to optimal voltage and reactive power control based on a genetic algorithm (GA), and attempts to shorten the time of the GA, which calculates the control process. For this purpose, a network is decomposed into subsystems by means of region/area information, and the control counts of the controller are considered in the voltage and reactive power control. Therefore, some methods that give the control procedure are proposed in the GA algorithm. The effectiveness of the proposed method is demonstrated by practical 15- and 118-bus systems.
