Applying the DC distribution system constructed commercial buildings

By applying new technologies of energy and DC distribution technology, the smart-grid based digital load device is increased. Due to the power conversion technology, the power consumption is minimized, maximize the utilization of self-development self-energy power consumption. Derive optimum efficiency power structure, and at the same time, the existing AC system with high quality bi-directional AC-DC power associated with a stable power supply, IT and communication technologies, combines DC smart metering, use of power management with ultra-low power / high reliability sensor networking and information a new concept of the DC power distribution, display, DC load systems (LED lighting, office equipment, etc.), and predict the power consumption of the load device control and distributed power distribution integrated power operation, the heating equipment operation through predictive diagnostic and maintenance optimization techniques, such as that obtained applies Korea-Micro Energy Grid Test- bed will be constructed.
