Abstract
The new concept that several local energy networks including distributed power generations such as micro gas turbine and fuel cell are integrated and controlled by means of the Internet technologies is proposed to operate the distributed power generation systems in high efficiency. In this paper, the possibility and advantage in costs of Line Power Supply concept which is the base of our new energy network concept are discussed. The infrastructure for railroad power supply is utilized in the Line Power Supply concept. Moreover, the advantage of the integrated local energy network concept to which the Line Power Supply concept is applied is described.
