Abstract:

The usually small and weak electrical grids present obstacles to maximum Renewable Energy Sources (RES) penetration in island regions, associated with the technical limitations and difficulties to manage power fluctuations.

The need to have back-up conventional power systems on standby for when wind is dropping and stops blowing or when the sun does not shine, even simply due to clouds passing overhead, is an important cost that has to be supported by local utilities.

Besides, high percentage penetration of intermittent RES generated electricity induces stability problems in the islands electrical systems. Indeed, rapid reductions in the power output from RES must be managed with appropriate control or energy storage systems to maintain constant power output.

In this context, enhanced forecasting, operations and planning tools can contribute to increase RES penetration. The proficiency of such tools is reinforced if they are combined with uncertainty and risk management methods.

This Keynote Speech addresses the effects of large-scale integration of RES on the optimal operation and planning of insular power systems, proposing efficient measures, solutions and tools towards the development of a sustainable and smart grid, all under the EU-funded FP7 project SiNGULAR (a 5.2 million euro project involving 11 industry partners).

The goal is the generation of effective solutions and information so that the integration of insular and highly variable energy resources is maximized. The optimal forecasting, operation and planning tools have been applied in different insular electrical grids in five countries across Europe for extensive demonstration, allowing the development of generalized guides of procedures and grid codes.

Abstract:

Power systems are going through a paradigm change from centralised generation, to distributed generation, and further on to smart grids. A huge number of renewable energy sources, electric vehicles, and storage systems etc. are being connected to power systems. Moreover, various loads are being required to take part in demand responses and to improve energy efficiency. These make it impossible to control and operate power systems in the conventional way, simply because of the huge number of players in the system. In this lecture, an architecture and its associated distributed control strategy, which are based on the inherent synchronisation mechanism of conventional synchronous generators, are presented for next-generation smart grids so that the majority of the players, including all conventional power plants, new add-ons of suppliers and most loads, will be able to synchronise with each other to achieve autonomous operation and maintain system stability, without the need of a dedicated communication network. The function of communication is achieved through control.

Martini has been recruited by organizations as EC and US DOE as independent expert to peer review publicly funded applied R&D projects.

Abstract:

The Strategic Energy Technology plan (SET-Plan) aims to help achieving Europe 2020 and 2050 targets and visions on greenhouse gas emissions, renewables and energy efficiency by increasing research, reducing costs and improving performance of existing technologies, encouraging their commercial implementation, and, in the longer term, supporting the deployment of more efficient new low carbon technologies.

In this context, the electricity grid can play an important role and therefore, a suitable portfolio of innovative technologies needs to be researched, developed and deployed in order to preparing the European electricity networks to enable the ambitious agenda adopted by the European Member States.

Apart from introducing some of the most relevant initiatives for the achievement of the SET-Plan ambitious goals, namely the European Industrial Initiatives (EII), the European Technology Platforms (ETP), and the European Energy Research Alliance (EERA), this keynote speech will present goals and activity of the EERA Joint Research Programme (JP) on Smart Grids (SG).

By means of an extended cross-disciplinary cooperation involving, at present, 36 research organizations from 17 different European countries with different and complementary expertise and facilities, the EERA JP SG aims at addressing in a medium- to long-term research perspective, the most critical areas directly relating to the effective acceleration of smart grid development and deployment.

This represents a new and more effective way of working at European level in order to tackle with the complexity of the research smart grid challenges.

The research activity of the JP SG, covering active distribution network, integrating distributed generation from renewable energy sources, load management issues, electrical storage systems, and transmission networks, is hence reported and discussed.

Abstract:

After 130 years of the development, power systems are at cross roads. The originally envisioned concept of centralized bulk generation, highly available transmission system, radial distribution system and passive load does not seem to be sustainable. The highly variable renewable sources, heavily utilized transmission, distribution with bidirectional flows and loads/microgrids that can act as a resource are recognizable trends for the future. This talk focuses on the role of Big Data in managing and controlling future power system, which will be characterized with “explosion” of data and unprecedented computational and communication capabilities to automatically extract the knowledge.

This talk will reflect on unique impacts from different data sources that range from field measurements obtained through substation/feeder intelligent electronic devices such as Digital Protective Relays (DPRs), Digital Fault Recorders (DFRs), Phasor Measurement Units (PMUs), etc. to other data sets obtained from specialized commercial and/or government/state databases: weather data of different types, lightning detection data, seismic data, fire detection data, etc. Due to the massive amount of such data (terabytes) available in real time and through historical records, processing and management of such data requires revisiting data correlation and feature extraction strategies already developed in the Big Data industries such as banking, insurance and health care. This talk will focus on the differences between the Big Data properties in the power industry where the temporal and spatial properties, as well as correlation to the power system and component models are necessary for an efficient data uses.


5. High-Efficiency Silicon Carbide Power Electronics: Today and Tomorrow


 

Prof. Hans-Peter Nee (Royal Institute of Technology, Stockholm, Sweden) [Biography..]

Hans-Peter Nee was born in 1963 in Västerås, Sweden. He received the M.Sc., Licentiate, and Ph.D degrees in electrical engineering from the Royal Institute of Technology, Stockholm, Sweden, in 1987, 1992, and 1996, respectively. In 1999 he was appointed Professor of Power Electronics in the Department of Electrical Engineering. His interests are power electronic converters, semiconductor components, and control aspects of utility applications, like FACTS, HVDC, wind power converter systems, and variable-speed drives. At present, the two main focus areas are multilevel converters for high-power applications and high-efficiency SiC power electronics for various applications.

Prof. Nee has served in the board of the IEEE Sweden Section for many years and was the chairman of the board during 2002 and 2003. He is also a member of EPE and serves in the Executive Council and in the International Steering Committee. He is also an associate editor of IEEE Transactions on Power Electronics, and was the Guest Editor-in-chief for the special issue on “wide bandgap power devices and their applications” in published in the same journal in May 2014.

Abstract:

With the silicon carbide (SiC) power devices available today it has been shown that converter efficiencies exceeding 99.5 percent are possible. The main ideas behind such designs are discussed along with examples of converters. Module parasitics are problematic, and often parallel-connection of discrete devices provides superior performance compared to modules. New improved module designs with lower parasitic inductances are necessary for SiC power devices. With existing technology, however, products in different application areas can be developed. For this purpose, the reliability of SiC devices, packages, and systems must be investigated. An attempt to foresee new devices, modules and their applications is also made.


6. Practical use of wide bandgap semiconductors in power module implementations


 

Dr. Lee Empringham (University of Nottingham, Nottingham, United Kingdom) [Biography..]

Dr. Lee Empringham is a Principal Research Fellow within the Power Electronics Machines and Control Group, part of the Electrical Systems and Optics research division within the Faculty of Engineering at the University of Nottingham.

He received a B.Eng (hons) degree in Electrical and Electronic Engineering from the University of Nottingham, UK in 1996. He then joined the Power Electronics, Machines and Control Group at the University of Nottingham, UK to work on matrix converter commutation techniques. He received his PhD degree in November 2000. Since then he has been employed by the group as a Research Fellow to support different ongoing power converter projects and was promoted to Senior Research Fellow in 2007 and Principal Research Fellow in 2011. His present research interests include Direct AC-AC and Direct AC-DC power conversion, Variable Speed AC Motor Drives using different circuit topologies and Micro-grid interface converters to improve grid resilience and robustness and the use of wide bandgap semiconductors for high power converters. His research efforts have led to the creation of practical industrial prototype power converters ranging from 2kW to 200kW for aerospace, marine, automotive and industrial applications for companies including, Boeing, Airbus, Infineon and GE.

Abstract:

As the desire for increased power density and reduced losses pushes the switching speed of modern power devices to ever increasing levels, Low level interactions with parasitic elements within the power module become increasingly more important together with increased potential for Electro-magnetic Interference. The standard ‘add more devices’ approach to building high current power modules restricts the potential gains which are promised from modern wide bandgap power devices in that, increasing power module sizes increases parasitic component values and the potential for EMI emissions.

This speech will highlight the problems with present power module approaches with respect to the use of high speed devices and will outline a modular approach to the design and construction of high power converters which also addresses the increasingly important EMI issues of modern power converters.
