Electric WIRE & CABLE, ENERGY132 DC Micro grid System1. IntroductionHow can we increase the amount of photovoltaic (PV)generation? From this viewpoint, we are overviewing elec-tric facilities from power plants to Electric appliances in de-mand sites. PV modules generate DC Electric power. Thepower should be converted to AC that is synchronized withcommercial grids to be transmitted and distributed to de-mand sites. To reduce energy dissipation through thetransmission, the power is sent near the demand site afterbeing raised the Electric voltage to 66 kV or higher. Thepower is transformed to 100 V and provided to residentialoutlets after multi-processed reduction in voltage at substa-tions and pole-mounted transformers.
