 note = {application/pdf, Since there was an awareness of the negative environmental impact from carbon dioxide emission from conventional power generating system which fossil fuel, coal, and natural gas were involved, the trend of renewable energy usage was arisen as the global annual additions of renewable power capacity in 2019 is 74% higher than in 2013. The trend will continue in the same direction as it is stated in the road map to 2050 for the global energy transformation that renewable energy share in power generation should be increased to 86% with annual solar PV and wind additions up to 360 and 240 GW per year respectively.
To achieve those aims, the efficiency of the renewable power generating system must be considered, especially to overcome obstacles due to unpredictable characteristics of natural power sources. To combine the sources is one of the promising solutions. Therefore, hybrid power generation was introduced. In our research, the wind power is added to the existing photo-voltaic (PV) power generation system to increase the efficiency of the system from the lack of solar irradiation during night time and unpleasant weather conditions, hence PV Cell Cooperating System (PVCCS) is given as its name.
The PVCCS is comprised of the PV power generation system (PVPGS), the emulating circuit, an electric double-layer capacitor (EDLC), a bi-directional boost chopper, a filter, a power conditioner system (PCS) and a simplified grid. As there are many nonlinear elements included in the system, the purpose of this study is to investigate the frequency response of them by numerical and frequency analyses and verified simulations. To analyze the frequency characteristic, the transfer functions are derived by the state-space averaging method and analyzed by Bode, Nyquist, and Lyapunov Stability Criterion. The trial and error method is used to define the PI parameters to make the system more stable. Therefore, an evaluation to improve the system performance can be conducted. The stability and efficiency of the system are improved after the evaluating processes are done., 三重大学大学院 工学研究科 電気電子工学専攻, 100p},
