태양전지의 모델링을 이용한 PCS 특성에 관한 연구 A Study on the Characteristics of PCS Using a Modeling of Solar Cells BY KIM SUNG-SOO Electrical & Electronic Major Semyung University Graduate School 
ABSTRACT
 In this paper, we modeled the devices used in PV system easily. Simulation tools use PSPICE to enable intuitive electrical circuit simulations. Simulations were also performed on the effects of temperature and spatial radiation that are easy to overlook when using solar cells using modelled libraries. In addition, for full operation of the photovoltaic system, a complete operation system for the DC-DC buck-boost converter and the MPPT(Maximum Power Point Tracking) control system was modeled and simulated to confirm good operation. In order to verify the operation of the simulation, we constructed an actual system with the same conditions in the simulation and experimented. As a result, we proposed a single-phase 3 kW grid-connected solar power converter. In addition to IGBT devices and GaN type MOSFETs We have obtained design data that can be diversified and increased in capacity considering the capacity. Especially, it is confirmed that GaN type MOSFET is the next generation switching device. It is possible to expand the switching frequency to 200 [kHz] and greatly reduce the size of the heat sink which can greatly improve efficiency and power factor. In future, it can be used as a stand-alone system with ESS using solar inverter, and it is possible to regenerate energy to the battery power side, and it has efficiency of 95% or more and energy saving effect is confirmed.
