Large power plants are far away from power consumption areas such as urban areas and industrial parks, and the power loss during the distance between the power plants and the consumption areas is large. In addition, the amount of energy used for power transmission also increases, which has a large impact on the environment in terms of CO2 emissions. On the other hand, in a microgrid using hybrid energy, small-scale power plants can be set up near power consumption areas, enabling local production for local consumption of electricity and reducing various problems. Natural energy sources such as solar, wind, and biomass can be used as energy supply sources. They can provide a stable and environmentally friendly energy supply by securing backup power sources and managing and operating them using information and communication technology called an Energy Management System.
