碩士 === 明新科技大學 === 電機工程研究所 === 103 === This study presents the control of the reactive power compensator and OLTC effectively to improve the power quality and reduce line losses in the distribution system with distributed generator. The bus voltage is often high or low connected distributed generator. Therefore, these properly controlled OLTC tap settings and the reactive power compensation to avoid the phenomenon. This paper applied Hybrid Differential Evolution (HDE), Particle Swarm Optimization(PSO) and Genetic Algorithm (GA) to design the novel optimum procedure technique. The novel optimum procedure technique coordinated the OLTC setting and reactive power compensation for reducing line losses and improved the power quality. For the example, the IEEE 21 bus and the IEEE 14 bus distribution system with distributed generators is verified using these advanced algorithm. In consideration of the different loads, the novel optimum procedure technique used Genetic Algorithm, Differential Evolution and Particle Swarm Optimization to coordinate and tuning the OLTCs setting and reactive power compensation for reducing line losses and voltage drops of distribution system.
