Towards Interoperability Testing of Smart Energy Systems – An Overview and Discussion of Possibilities

Interoperability is the key to implementing a wide range of energy systems applications. It involves the seamless cooperation of different methods and components. With smart energy systems, interoperability faces challenges due to integrating different approaches and technologies. This includes dealing with heterogeneous approaches with various communication protocols and data formats. However, it is essential for smart energy systems to carry out thorough interoperability tests. They are usually diverse, and challenging, thus requiring careful consideration of compatibility issues and complex integration scenarios. Over-coming these challenges requires a systematic approach that includes thorough test planning, rigorous testing, and continuous test monitoring. Although numerous testing approaches exist, most are more developed at the component/device level than at the system level. Consequently, there are few approaches and related facilities to test the interoperability of smart energy ap-proaches and solutions at the system level. This work analyses existing interoperability test concepts, identifies enablers and the potential for harmonisation of procedures, and proposes further developments of these approaches.
