Many different approaches are currently utilized in the field of integrated network control systems, known as smart grids. We implemented an energy management system with the aim of developing a future standard for this area. It is difficult to connect heterogeneous systems that contain different standards, even if standardized technologies are available. A concept for an integrated network control system is proposed and demonstrated to overcome this problem. We considered distributed and shared operations in a large system containing various subsystems. This concept maintains interoperability between heterogeneous systems. The concept was demonstrated at the Fukue Port Terminal building in Goto City, Nagasaki Prefecture. A field demonstration of the building energy management system was conducted in the building. This system uses a variety of devices that are produced by seven different companies. An air-conditioning control system to reduce carbon dioxide emissions and achieve electric-load leveling with a battery was implemented and experimented with an application of the proposed system. The battery was emulated by real-time system simulation. Our results demonstrate the effects of a common platform and its advantages.
