| Summary: | 碩士 === 南臺科技大學 === 電機工程系 === 103 === This thesis investigates the maximum photovoltaic generation system(PVGS)
installation capacity by considering the load flow analysis and transient stability
analysis for a small scale island power system. The Chi-Mei Island is selected for
computer simulation. First, the power system topology, generator’s models and load
are collected in detail. Then the one-line diagram and the associated generator
control model are set up in the Cyme Psaf program. Furthermore, this paper also
collects the power output of an existing PVGS and related climate data for statistical
analysis. It is therefore to know the ramp rate of the PVGS and to propose a PVGS
model based on the regression analysis method.
Many various load flow analyses are executed with and without considering the
connection of PVGS. The voltage variation ratio(VVR) is obtained according to the
simulation results. After that, a power controlled strategy of smart inverter is applied
to reduce the VVR. The penetration of PVGS can be increased significantly by the
proposed method. Then the transient stability analysis is executed with considering
the tripping and power variation with various ramp-rates of PVGS. The dynamic
response of diesel generators, voltages and system frequency are examined carefully.
It is therefore to obtain the maximum installation capacities of a single and total
PVGS without violating the lowest frequency limit. The execution of this thesis can
improve the penetration of PVGS. It is very helpful to the development of
sustainable energy.
