About COBEP

The main objectives of COBEP (Brazilian Power Electronics Conference) are to promote a forum to discuss research, development, applications, new trends, and latest advances in Power Electronics and Electrical Machine Control.

The event is open for the whole community, but it mainly targets specialists in Power Electronics, Electrical Drives, and Machine Control. Researchers, engineers, businessmen, and engineering students are encouraged to participate in COBEP.

COBEP has technical co-sponsor from the IEEE (The Institute of Electrical and Electronics Engineers), through a cooperation agreement with PELS (Power Electronics Society), allowing its internationalization and increasing its divulgation. It is a bi-annual event that is organized every odd year by one or more Universities, Research Groups or Institutes from various regions of Brazil.

COBEP 2013 is organized by the Federal University of Santa Maria (UFSM), and will take place in the touristic town in the southern Brazilian state of Rio Grande do Sul, Gramado, from 27 to 31 October 2013.

Currently, COBEP is the national meeting of Brazilian researchers of Power Electronics and Applications. The organizers are expecting and welcoming increasing participation from the international scientific community, to further strengthen this consolidated forum of advanced technical discussions.

Smartgrids: Stakes, Reality and Perspectives

(Download Presentation)

Prof. Nouredine Hadjsaid, Ph.D.
Grenoble Institute of Technology, Domaine Universitaire, France

Oswaldo Kaschny
Schneider Electric, France

Abstract

Electrical power systems are facing significant challenges including security of supply, environmental issue and multiplicity of actors in the most complex infrastructure ever built by a man. Thus, in many countries, the expected response to the problem of efficient and sustainable supply of electrical energy is the development of what is commonly called “Smartgrids.”

Indeed, in many different parts of the world, objectives in terms of energy efficiency, CO2 emission reduction and renewable energies shares in the energy mix are set up for a given horizon. This is the case with the European Union by adopting “the climate and energy package” with ambitious sustainability targets such as the 3*20% targets for 2020 indicating the aim to reduce CO2 emission by 20% compared to 1990, to increase the energy efficiency by 20% and to increase renewable energy share within the existing electrical infrastructure by 20%. Even more ambitious targets are being considered for 2035 and 2050. This clear signal defines a way forward for a transition to a carbon free society. All stakeholders of the electricity sector are affected and significant evolution is undergoing in the electrical grid to accommodate the assigned targets. This also implies heavy investment in low carbon technologies and other technical innovations as seen as key enablers for this change.

This will most likely lead to major adjustments modifying the core mission of some energy key segments such as distribution grids. Indeed, the distribution networks were not designed to operate with a massive penetration of generating units called Decentralized or Distributed (DGs) which are often of intermittent type (photovoltaic and wind power among others) as well as new usages such as plug-in electric and hybrid vehicles (PHEV). As such, their mission is transforming from delivering electricity one-way to an active management of grid flows and information.

Among the technical objectives of the SmartGrid concept, one can mention an increased integration and management of distributed generation as well as PHEV in the best economical and security conditions, an increased participation of consumers (concept of active consumer and optimization of consumption), an a reduced environmental impact of the whole electricity supply system (reducing losses, improving energy efficiency, among others), an improved power quality and overall system security, etc. The field of expected achievements is as broad as efficient devices/structures for interconnecting DGs, control and supervision, energy chain optimization, reduction of peak consumption, anticipation of equipment failures and self-healing to manage outages and improve network resilience, etc.

The extent of technology to be developed for reaching these objectives encompasses several areas that include information and communication technologies, new monitoring and control devices, adapting equipment for fault management, advanced forecasting tools, etc. The EU Technology Platform SmartGrid indicated an interesting table of the technology move within the SmartGrid concept.

In view of drivers and objectives mentioned above, the concept of “SmartGrid or “Intelligent Network” is a significant research program in itself over a different time horizons (short, medium and long terms). It involves several stages including research, development, pilot demonstration and deployment. Some of the “smart” technologies are already available, other under development and most are to be invented. Several research projects are underway throughout the world. These projects are either funded by government agencies or communities or industrial organizations and other consortia.

In this context, power electronics technologies play a major role, namely for the efficient integration of DGs such as PV (Photovoltaic) of even wind turbines that are based on variable speed synchronous generators, DC and Supergrids, and the large variety of power electronic based devices embedded into the grid for controlling in real time various grid parameters such as power flows, voltages, current limitation for example. In addition, the ongoing development of PHEV is highly dependent on the “smart” solutions to be provided thanks to power electronics development.

The presentation will address the advent of Smartgrids, solutions being developed to meet the increasing complexity of the whole electrical system and some project initiatives throughout the world. It will cover both up to date research and development in the field of Smartgrids and industrial applications including power electronics applications for Smartgrids.

Modulation for Static Power Converters

(Download Presentation)

Prof. Humberto Pinheiro, Ph.D.
Federal University of Santa Maria, Brazil

Oct. 29th, Tuesday, 8:30 am – 10:00 am

Abstract

This lecture will address the modulation for static converters. It starts by reviewing classical “Selective Harmonic” and “Carrier Base Modulation”, their spectra and applications in single phase, in three phase with three and four wires, as well as, in cascade multilevel converters. Then, the degrees of freedom of multilevel converters are explored in a systematic way by using a “Geometric Approach” providing a simple tool for power electronics engineers to explore the entire converter capabilities in the well-known carrier based framework. Finally, the “Space Vector Modulation” is presented for different converters from single phase to three phase cascade converters where its main advantages and challenges discussed.

Voltage-Source Converters for HVDC Systems

(Download Presentation)

Prof. Josep Pou, Ph.D.
University of New South Wales, Australia, and Technical University of Catalonia, Spain

Oct. 30th, Wednesday, 8:30 am – 10:00 am

Abstract

High-voltage direct current (HVDC) has become a key technology for remote renewable generation, such as off-shore wind farms, as well as for strengthening existing AC grids. Most of the HVDC transmission systems in operation today are based on line-commutated converters (LCC) based on thyristors. However, because of the limited degree of freedom in the control of the thyristors, LCC-based HVDC systems have important limitations such as that they cannot feed power into a passive system or help to recover AC grids from voltage sags or blackouts. Furthermore, to reverse the flux of power, the DC voltage polarity needs to be changed, which is an important inconvenient for the operation of multiterminal HVDC systems. In contrast, voltage-source converters (VSCs) based for instance on IGBT, maintain a constant polarity of the DC voltage and power reversal is achieved by reversing the direction of the current. They can also operate over passive loads and contribute to recover AC faulty grids by injecting reactive power.

The two-level converter is the simplest type of three-phase VSC. Several power devices have to be connected in series in order to meet the voltage levels required in HVDC applications. Because two-level converters provide low harmonic performance, multilevel converters have become the clue technology for VSC-based HVDC systems. Some multilevel topologies used in HVDC systems are the neutral-point-clamped converter and several configurations of modular multilevel converters. This session will be devoted to the analysis of VSC for HVDC applications.
