A Study on PCS Characteristics Using Modeling of Solar Cell

Abstract

In this paper, we modeled the devices used in PV system for easy analysis. The modeled library was used to simulate the effects of solar cell temperature and spatial radiation. In addition, the operation of the DC-DC buck-boost converter and the MPPT control system was modeled and simulated for complete operation of the PV system. In addition, to prove the operation of the simulation, the experiment was performed by configuring the actual system under the same conditions as in the simulation, and it was confirmed that the results of the experiment and the simulation result performed the same operation. In addition, we proposed a single-phase 3kW grid-connected solar power converter and confirmed the possibility of great help in improving efficiency and power factor. In the future, it can be used as a stand-alone system when attaching ESS by using solar inverter, and it is possible to regenerate energy to the battery power side, and it has efficiency of more than 95 [%] and has an energy saving effect.
