In order to perform photovoltaic (PV) operation and management (O&M) efficiently, individual PV module monitoring is becoming more important. In this research, we developed wireless IoT sensor which can monitor individual photovoltaic modules. This IoT sensor can detect the output voltage, current and module temperature of individual modules and provide monitored data by wireless communication. Measured voltage error was 1.23%, and it shows 16.6 dBM, 0.42sec and 7.1 mA for voltage, transmittance output, response time and mean power consumption, respectively. IoT sensors were demonstrated in the test field with real climate environment condition and each of 5 sensors showed precise results of voltage, current and temperature. Also, sensors were compared with commercial power-optimizers and showed result difference within 5%.

In this study, we predict the generation of end-of-life photovoltaic modules when Feed in Tariff applied, in Republic of Korea. Based on the installation of photovoltaic modules, we prepared three different senarios in order to estimate the generation of end-of-life photovoltaic modules. The senarios are i) early worn-out, ii) mid worn-out and iii) late-worn out senario. We selected the mid worn-out senario to estimated the amount of end-of-life photovoltaic modules in this study. Establishment of the end-of-life module generation scenario predicted generation of end-of-life photovoltaic module, and forecasted generation amount of end-of-life module to which Feed in Tariff was applied in consideration of installed photovoltaic modules installed by Feed in Tariff support. The generation of Feed in Tariff-applied end-of-life modules increased from 2021 to 2025 compared to without Feed in Tariff, and since then, the Feed in Tariff-applied end-of-life modules were generated as waste modules during the relevant period (2021 ~ 2025).

Recently, the ultra-precision stage is widely used in the fields of the nano-technology, special1y in AFMs(Atomic Force Microscope) and STMs(Scanning Tunneling Microscope). In this paper, the ultra-precision stage which consists of flexure hinges, piezoelectric actuator, and ultra-precision linear encoder, is designed and developed. The guide mechanism which consisted of flexure hinges is analyzed by Finite Element Method. And we derived the transfer function of the system in 1st order system from step responses according to the magnitude. We performed simulation for the model to tune the control gain and applied the gains to the developed system. Experimental results found that the stage can be control1ed in 5 ㎚ resolution by PID control1er.

The ultra-precision positioning system is demanded for some industrial fields, such as semiconductor lithography and fabrication of the nano structure. In this paper, the ultra-precision stage which consists of flexure hinges, piezoelectric actuator, and ultra-precision linear encoder, is designed and developed. From the step responses of the system, the system transfer function of the ultra-precision stage system was derived by a second order model system. In order to have robustness for the system uncertainty and external disturbances, the weighting functions were selected and the H∞ controller was designed using them. For the designed controller, the simulation was performed and the designed stage system was applied. Experimental results found that this stage could be controlled below 5㎜ resolution and irrespective of hysteresis and creep by this designed controller.

The nano-stage system is widely used in some industrial fields, such as semiconductor lithography and fabrication of the nano structure. In this paper, the nano stage which is designed and fabricated is consisted of flexure hinges, piezoelectric actuator, and ultra-precision linear encoder. In order to make a system transfer function of the nano-stage system, the frequency responses for the sinusoidal inputs was analyzed. From the bode diagram, the system was modeled in 4th order system. Also, in order to have robustness for the system uncertainty and external disturbances, some weighting functions were selected and the H<SUB>∞</SUB> controller was designed by loop-shaping method. For the designed robust controller, the simulation was performed and the designed stage system was applied.
