    Traditional electrical grids are shifting towards Smart Grids that could deliver electricity in sustainable, economic and secure way. Simultaneously, characteristics of electrical grids are becoming much more complex that require development of several Smart Grid functionalities. This thesis studies architecture modeling of Smart Grid Testing Platform (SGTP) and integration of MultiPower laboratory. The architecture was defined in collaboration with research project team in a project called “Integrated business platform of distributed energy resources” (HEILA). Furthermore, the main goals are to produce an architecture model, which promotes specific Smart Grid related use cases, and interconnect the MultiPower laboratory with the platform.

    This thesis is divided into two parts. Firstly, background, challenges with Smart Grids, the HEILA project and MultiPower laboratory are introduced. Then, Smart Grid Architecture Model (SGAM) Framework, tools and related architecture definitions in different projects are studied. In addition, information models defined by IEC 61850 standard and Common Information Model (CIM), Smart API, HyperText Transfer Protocol (HTTP) and MQ Telemetry Transport (MQTT) protocols are studied because of their central role in the architecture model and integration. Secondly, results are presented with descriptions of the architecture model and integration process.

    The architecture model presents how different actors cooperate in order to offer and use flexibility related services on distribution level. The architecture model increases level of details, adds functionalities and changes some of the protocols used when compared to the related architectures. Additionally, self-descriptive and more flexible messaging are introduced as messages contain semantic information and they are not bound to any specific format. The function positioning with two-way communications promotes decentralized data acquisition and control. Generally, that may ease market integration, privacy, autonomy and scalability issues. As a result, the architecture may promote development and utilization of different kind of flexibility related services and products. However, information objects should be added to the standard mapping on information layer of the model since it would increase level of details. The integration was successful since monitoring and controlling of the MultiPower equipment is possible with current version of the SGTP as tests demonstrate. Technical requirements in the use cases were fulfilled.

    In future research work in the HEILA project message encryption, validation and CIM utilization should be considered. Moreover, Energy Management System (EMS) and equipment that is more suitable for routine testing should be considered for the MultiPower.
