Given the massive early investment needed for the construction of large offshore wind farms, the ROI (return of investment), which can guarantee sufficient profitability, should be secured in advance. The highest priority in terms of determining profitability is to estimate the power production volume of an offshore wind farm based on surveyed wind resources. The maritime measurement of wind resources...
In case of installing a room of a battery for recharging an electric car, it is necessary to have a system to keep the best state of a battery and to control the recharge and discharge of power. This paper is about the measuring module for the status information of a battery and the development of a battery management system to manage individual battery in a room of a battery with 120kWh grade. It...
Korea has been developing coast has been developing wind energy on land for a long time, and the government is in preparations of an offshore wind farm for the first time. The conditions of the wind rose affect not only the structures of wind turbine, but are also important in predicting the future energy production rate. If an offshore wind farm is to be composed, it is the most important factor...
The photovoltaic module shows difference in efficiency according to the manufacturing method, and in case of operation mode, identical PV modules with the same manufacturer also become to show difference data in generation efficiency according to their management method. In other words, the unbalance of efficiency in specified modules connected as a series or a parallel array reduces the total generation...
