“…However, it is nearly impossible to change AC grid to DC grid instantly. Hence, there are researches that proposed the hybrid AC/DC system where the three-stage SST was implemented [133]. SST is only suitable in the microgrid (MG); However, not in a smart grid because of the limitation in power devices.…”

Solid-state transformer (SST) is an emerging technology integrating with a transformer power electronics converters and control circuitry. This paper comprehensively reviews the SST topologies suitable for different voltage levels and with varied stages, their control operation, and different trends in applications. The paper discusses various SST configurations with their design and characteristics to convert the input to output under unipolar and bipolar operation. A comparison between the topologies, control operation and applications are included. Different control models and schemes are explained. Potential benefits of SST in many applications in terms of controllability and the synergy of AC and DC systems are highlighted to appreciate the importance of SST technologies. This review highlights many factors including existing issues and challenges and provides recommendations for the improvement of future SST configuration and development.

“…Hence, although there is a dinstiction between the two topologies in the literature, they can coexist. Through the formation of a microgrid consisting of interconnected nanogrids [35][36][37], features such as local power sharing and communication between the various power entities are available.…”

Distributed generation (DG) systems are growing in number, diversifying in driving technologies and providing substantial energy quantities in covering the energy needs of the interconnected system in an optimal way. This evolution of technologies is a response to the needs of the energy transition to a low carbon economy. A nanogrid is dependent on local resources through appropriate DG, confined within the boundaries of an energy domain not exceeding 100 kW of power. It can be a single building that is equipped with a local electricity generation to fulfil the building’s load consumption requirements, it is electrically interconnected with the external power system and it can optionally be equipped with a storage system. It is, however, mandatory that a nanogrid is equipped with a controller for optimisation of the production/consumption curves. This study presents design consideretions for nanogrids and the design of a nanogrid system consisting of a 40 kWp photovoltaic (PV) system and a 50 kWh battery energy storage system (BESS) managed via a central converter able to perform demand-side management (DSM). The implementation of the nanogrid aims at reducing the CO2 footprint of the confined domain and increase its self-sufficiency.

“…A test with 100 cases has been conducted in order to validate the theoretical algorithms in the real Laboratory structure. Some of these tests can be analysed in [23]. In all cases, the errors when comparing theoretical and experimental cases are lower than 2V (in Voltages), and 1A (In currents).…”

In this work, the authors propose a new coordination method for Smart Distribution Networks (SDN) with nearly-Zero Energy Buildings (nZEB). The proposed coordination procedure considers a central controller that runs a state estimation of the grid and calculates the optimum set-points for the buildings. Inside each building, the Building Management System (BMS) manages the converters used by the Dispatchable Generators (DG), the Renewable Generators (RG) and the Energy Storage System (ESS) to fulfil (as far as possible), the central controller request. In the paper, the unbalanced behaviour of the grid is considered, so the optimum references for the symmetrical component currents in the converters are calculated. The proposed method reduces the network unbalance and the total losses. In addition, buildings with energy surplus can support other neighbours with energy deficit. The present paper is focused on how the BMS calculates the optimum references for all converters placed inside each building. The main contribution of the paper is the use of the symmetrical component approach at building level in order to generate the best references for all converters inside the building.
