Reactive Optimal Planning Of Distribution Considering Of Harmonic Factors

In the distribution system, many capacitor banks are applied to decrease the loss of the network. The harmonic resonance may be incurred between the network and the capacitor banks in the harmonic frequency, thus the security of the system may be destroyed because of the high harmonic distortion level. To handle this problem, the Mathematical model of distribution optimal operation was set up in the paper. A specific method named genetic algorithm, which was refined by the sensitivity methods applied in the model. In short, the system power loss and harmonic distortion are minimized, while being satisfied the voltage amplitude constraints and harmonic constraints, and the economical effect is better. The results proved the effectiveness of the refined method and the speed of the Genetic Algorithm increased greatly.He Chun (power system and its automation)Directed by prof. Zhao Shuqiang...
