계통 연계형 태양광 발전 시스템의 스마트 블랙박스의 개발

In this paper, we developed a smart black box that can monitor and record the information of the sensor from subsystem in the smart grid system. The plant is the complex power system which is integrated by solar power system, grid-connected power systems, and BESS(battery energy storage system). The black box with the web-server application can connect and synchronize to an external monitoring system and a smart phone. We hope that this system is to contribute toimprove operational efficiency, reliability, and stability for the smart grid power system.
