碩士 === 國立臺灣科技大學 === 電機工程系 === 96 === This thesis analyzes the effects of a grid-connected photovoltaic (PV) generation system on the voltage and frequency of a real isolated island power system in Taiwan. A 350 kW PV system to be connected with the electric utility of the island is investigated in this thesis. Simulations of the isolated island power system and the PV grid-connected system are realized using Matlab/Simulink. A complete transient and dynamic stability analysis is investigated. Impacts of PV system connection locations in the isolated island power system, solar irradiation variation and optimal operational mode of diesel governors are studied. PV system dynamic behavior during three-phase fault is also included and proper connection capacity of PV system is estimated. Simulation results show a considerable effect of the PV system on voltage and frequency fluctuations. It provides a suggestion of generator locations on the isolated island power system in the future.
