Power flow control for micro grid with interconnection device using semiconductor-based switch and bidirectional inverter

In recent years, the concepts of the smatt grid and the smatt community have received attention as a new infrastructure for more prudent use of energy, electricity in particular, with less waste and more convenience. Here, we describe a combined renewable energy system that optimizes energy use and increases robustness against disasters by integrating various distributed power sources such as the existing power grid, solar energy and storage batteries on the demand side and by using ICT.
