Genetic algorithm base reactive power dispatch and voltage control

Abstract

Reactive power control becomes extremely important after deregulation because costumers request high quality power supply with reasonable price. Also the Voltage profile at different nodes in the power system is affected greatly by the variations in load and generation profiles during normal and abnormal operating states. The reactive power control devices such as generators, tap positions of on-load tap changer of transformers, shunt reactors are used to correct voltage limits violations while simultaneously reducing the system real power losses. Genetic algorithms (GAs) are well-known global search techniques anchored on the mechanisms of natural selection and genetics. Hear i present the work on genetic algorithm for reactive power optimization and voltage control. The objective of genetic algorithm base reactive power optimization is minimizing active power losses while maintaining the quality of voltages.
