Supervisory Control and Data Acquisition for Distributed Smart System = Supervisory Control and Data Acquisition using a Resilient Information Architecture Platform for Smart System

The today Energy system is characterized by the more and more growth and diffusion of the various distributed energy renewable sources in the generation and distribution level, such as wind and solar, are marked by the intermittent and variable generation. Moreover, now the customer can become a prosumer, it is no longer the last in the hierarchical order of the energy system, it can produce energy for itself and also feed the grid, so now need to be more integrated and in touch with the grid system. These aspects bring the necessity to evolve the actual power grid system that can't handle those changes. The emergence of the Smart Grids proposed as the electrical system of the future seems to be the technology that can provide the possibility to address those problems, creating an Internet of things application. However, this new power system actually presents the important lack of standardized communication and control protocols and a suitable platform to host it and simplify its diffusion. This thesis aims to provide a solution to those problems developing a Supervisory Control and Data Acquisition (SCADA) system integrating a Resilient Information Architecture Platform for Decentralized Smart Systems (RIAPS). In particular, that SCADA relies on Modbus and MQTT system interaction based on C++ and Python codes launched through the innovative middleware RIAPS. It has been examined the effects of the developed work directly in the target environment of a Smart Grid; everything has been tested in the Green Energy Hub testbed of the FREEDM Systems Center, that reproduce a possible Smart Grid environment made up of three microgrids. Therefore it was possible to use and test the real and innovative power electronic devices proper to a futuristic system including Low-Voltage Solid State Transformer. Moreover, it is necessary to underline the importance of this project, which represents the first real application of a power system running on RIAPS. The obtained results demonstrate the strengths of this novel Smart Grid platform and that this thesis constitutes a valid way to follow towards standardization.
