Title: Solid-State Transformer Applications – A Glimpse Into the Future


Smart and/or Solid-State Transformers (SSTs) are power electronics interfaces between medium voltage and low-voltage AC or DC grids and are employing medium-frequency transformers for providing galvanic isolation and voltage scaling. Accordingly, SSTs show a high power density and are offering excellent controllability of the active and reactive power flow and/or voltage and current level and shape, as well as active protection features.

Early SST concepts date back to the 1970s, where research was mainly driven by the aim to reduce volume and weight of rail vehicles’ isolated AC/DC input stages. Later, possible applications in the context of Smart Grids shifted into focus, where the main drivers were enhanced power routing functionalities of power electronic systems compared to passive low-frequency transformers. This talk will first will first review current Megatrends, such as Clean Energy, Digitalization, Urbanization/Smart Cities, Sustainable Mobility, etc. and identify corresponding future applications for SST systems, especially in the context of DC microgrids and DC power distribution applications in datacenters, larger EV charging facilities, DC collector grids of off-shore wind parks, and future hybrid propulsion aircraft. Next, the talk covers key power converter topologies for the realization of SST systems which includes basic isolated DC/DC converter topologies, multi-cell converter structures with input-series / output-parallel (ISOP) configuration to achieve modularity and high reliability through redundancy, and structural options for realizing three-phase connectivity, as well as hybrid transformers. First industrial SST prototype systems are discussed to illustrate the practical applicability of the concepts. Finally, examples of current research activities on SST systems at ETH Zurich will be presented, including a highly compact/efficient 10kV-SiC-MOSFET-based converter module for future datacenter or ultra-fast EV charging applications.

Title: Model-based Design and Operations of Smart Energy Systems


The smart grid is the ICT answer to the power challenges of tomorrow: flexible loads, active distribution grids, storage management, smart energy markets, and bidirectional power flows. Conceptually it is a distributed ICT and automation system that is amalgamated with the physical power infrastructure: a cyber-physical system, and even a system of systems. Designing, optimizing, running, and diagnosing such systems requires reliable and scalable computational models which leads us to the main problem with cyber-physical systems: hybrid models (discrete and continuous) are hard to deal with. There are, however, new and promising languages and methods to deal with such systems.

This talk will introduce you to the challenges of describing such complex energy systems and show you how modern modeling methods can overcome the hurdles. Ultimately, such models are capable of covering technical constraints, economic drivers, and complex interactions in several magnitudes of time.

Title: Microgrids Research and Applications: Smart Homes, EV Charging Stations, Electrical Ships and Seaports


A microgrid is an electrical distribution network consisted of distributed generators, local loads, and energy storage systems that can operate in grid-connected or islanded modes. Different technologies are combined together, such us power converters, control, communications, optimization, and so on. This way the energy can be generated and stored near to the consumption points, improving the stability and reducing the losses produced by the large power lines. In distributed energy systems like microgrids, multi-agent systems technologies will be presented distributed control is a powerful tool for distributed.

In this talk examples of research and projects in real sites including conventional islanded systems installed in islands and rural remote areas, low-voltage distribution systems and AC and DC microgrids for residential applications and homes electrical vehicle charging stations, ships, vessels, and ferries, and seaports will be shown.

Title: Energy Storage for Smart Grid Applications


Lower renewable energy cost and escalating environmental concerns in the past 5-10 years have accelerated global deployment of renewable energy systems. However, further deployment of solar and wind energy systems is currently hindered due to the intermittent nature of these types of renewable energies. This intermittency problem combined with climate change impacts is causing grid instability and the mismatch between energy generation and demand which is leading to serious power infrastructure problems and significantly higher energy cost, especially during peak demand period. Many researchers, utilities, and regulators are evaluating various alternatives to mitigate these issues and energy storage is emerging as a leading candidate to address these challenges and facilitate further deployment of renewable energy technologies.

An overview of electrical and thermal energy storage technologies will be presented in this work but will focus on small to mid-size energy storage technologies for demand charge avoidance in commercial and industrial applications. The appropriate selection of a particular technology depends on the system requirements for the type of energy to be stored/used, discharge rate, capacity, lifetime, and cost. Lithium-ion batteries are a prominent candidate for smart grid applications due to their high specific energy and power, long cycle life, and recent reductions in cost. Special attention in this work will be on small to medium size grid-tied energy storage (i.e. 10 kW-500 kW) Li-ion battery and thermal energy storage systems that can help with demand charge reduction especially with applications that have a higher power to energy ratios.
