| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 104 === This thesis investigates the impact of PV grid-connected on the distribution feeder voltage, and presents the improvement method of voltage control for distribution feeder. It uses MATLAB/Simulink and ETAP to establish the Lin-bian distribution system as a study case, all kinds of PV grid-connected cases are used to simulate the situations in different load scenarios. If the current voltage control method cannot be used to achieve a reasonable adjustment, it will be able to install voltage regulator (VR) to improve the feeder voltage. Finally,the method could improve the voltage problem in the distribution feeders by using shunt capacitor, on-load tap changer and voltage regulator in hourly load and PV power generation.
