碩士 === 國立成功大學 === 電機工程學系碩博士班 === 95 === This thesis analyzes both dynamic and steady-state performances of a large-scale photovoltaic (PV) generation system connected to a utility grid. The impact analysis of the studied PV system on Taipower distribution system is also carried out. According to the characteristics of an inverter connected to a bus of a distribution system, the theory of inverter bus is proposed to solve power flow of the distribution system according to actual parameters of the PV system. The software EMTP-RV is employed to establish the model and calculate the power flow of the studied system. Steady-state characteristics of the PV system subject to changes of loading condition, photovoltaic output power, and grid voltage are performed. Dynamic characteristics of the studied PV system under various operating conditions such as islanding, stand alone, and loss of grid are also explored. The simulated results can be employed to determine the impacts of the studied PV system to the connected distribution systems under various operating conditions.
