Design for reliability in Power Electronic Systems
Prof. Frede Blaabjerg
Aalborg University, Denmark

In recent years, the automotive and aerospace industries have brought stringent reliability constraints on power electronic converters because of safety requirements. Today customers of many power electronic products expect up to 20 years (or even longer) of lifetime and they also want to have a “failure free period” and all with focus on the financials. The renewable energy sectors are also following the same trend, and more and more efforts are being devoted to improving power electronic converters to account for reliability with cost-effective and sustainable solutions. This presentation will introduce the recent progress in the reliability aspect study of power electronic converters for power electronic applications with special focus on renewables. It will cover the following contents: the motivations for highly reliable electric energy conversion in renewables; the reliability requirements of typical power electronic systems; failure mechanisms and lifetime models of key power electronic components (e.g., power semiconductor switches, capacitors, and fans); long-term mission profiles in renewable applications and their components; reliability analysis methods for more complicated systems, tools to be applied, and improvement strategies of power electronic converters in their applications. A few case studies will be given.

Power Electronics for future power grids: drivers and challenges
Dr. Alireza Nami
ABB Corporate Research Sweden

Currently, electric power systems start to shift toward more environment friendly energy productions to limit the climate change and reduce pollutions. The major focus is the variability of the new energy sources, and reliability of the supply. The challenge for the future electric power grids is how to integrate a widespread addition of renewable sources with intermittent nature in both transmission and distribution grids without compromising reliability, stability and cost of the service to the consumers. A system that can handle a generation mix with a high percentage of renewables will become a necessity which requires solutions as increased transmission capacity through AC and DC solutions, and/or a larger energy storage capacity in the grids.

Grid-connected converter technologies have had a truly revolutionary impact on the way that electrical energy is delivered to consumers all over the world, and has become an indispensable part of the electric power systems today. It is anticipated that by 2030 all electric power generated utilizes power electronics somewhere between the point of generation and its end. Power electronics contribute in many ways to more efficient use of energy, which allows for energy savings, which in turn leads to reduced environmental impact. The R&D in this field aims at optimizing complex decisions and solutions that are required for the design of these power electronic converters to deliver innovation for the future conversion, processing, transmission, distribution as well as storage of energy across a wide range of applications.

This presentation will start with an overview of the main drivers for the future grids. Then the historical, the present and the future power grid will be discussed including the developments of power electronics in grid-connected applications such as HVDC and FACTS together with more futuristic applications. Moreover, the key design parameters of power electronics and its functionalities will be described in the context of megatrends and grand challenges of the electric power system evolution. Finally, the current state of the art and topics for the future research will be presented.

Power Grids Control: drivers and trends
Bruno Luscan
Supergrid Institute

The energy transition objectives can’t be achieved without a massive integration of renewable energy sources into power grids. On one hand, this integration requires to reinforce large scale transmission system capacity, and interconnections between countries, in order to create an electricity market and the conditions for renewable energy trading. On another hand, conventional generation connected to the grid through synchronous generators is replaced by renewable generation which connected to the grid through power-electronics converters.

This trend leads to three major changes for the grid:

–          HVDC transmission is becoming an important part of the grid
–          AC system inertia is reducing and system dynamics are modified
–          Grid-connected power electronics converters can be controlled in order to support grid operation

The presentation will cover the following aspects of power grid controls:

–          The well-established principles of AC power system control
–          The principles of HVDC control, in a PtP link or in a multi-terminal system
–          The impact of AC system inertia reduction on power system stability
–          The contribution of Grid-connected power electronics converter to power system stability
–          The contribution of HVDC transmission to AC stability control

Starting from the physics of the system, a selection of key control challenges will be explained, and some major evolutions in power grid control will be put into perspective.
