Not every plug fits globally in every socket - this also applies for the future energy world. Each manufacturer has its own devices with their communication interfaces and protocols. Today, the user needs for each usage scenarios different devices, apps and software tools, which are usually not compatible with each other. This forces the user to use only apps and devices form always the same manufacturer. Together with other Fraunhofer Institutes Fraunhofer IIS has developed a flexible and secure open source framework for energy management systems as an »adapter« to enable interoperability between different devices of different manufacturers. OGEMA 2.0 (Open Gateway Energy MAnagement 2.0) allows the realization of different energy management systems for commercial, private and public buildings as well as industrial processes with only one system.
The framework uses a Java platform and standardized data models for the control of various energy producers, storages and consumers. The integrated app concept allows flexible installation of the application software for different utilization scenarios. Thus, the control of various devices via one or more web-apps within a smartphone can be implemented. Due to the hardware independency of the software, an easy adaption to different platforms such as PCs, servers or embedded systems is possible. Security enjoys a high priority in OGEMA 2.0, the allocation of individual access rights and usage rights are easy to implement.
The OGEMA 2.0 gateway can be used for optimal energy flow control and building management.Typical application fields are public buildings like schools or hospitals, business buildings and private households. This framework can also be used for the realization of various functions in the Smart Industry. The energy consumption of individual plants and machines can be easily captured, displayed and optimized. OGEMA 2.0 may also serve as an interface for the industrial plant.
