Tutorial 1: Signal Processing and System Performance Characterization in the Context of Smart Grids 

 

This tutorial will cover signal-processing techniques to evaluate system performance within the ever increasing complexity of smart grid context of applications such as detection, identification, monitoring, control, protection, impedance measurements, synchronization, decomposition, re-sampling of signals, among other topics.

The tutorial is related to a recent book from the authors entitled: Power Systems Signal Processing for Smart Grids, Wiley, 2013.

Tutorial 2: Robotic applications: a comparison between frameworks ROS and HTTPThru 

 

The implementation of several algorithms of localization, mapping, navigation and control of mobile robots require sophisticated algorithms to communicate and interact to several robotic devices and drivers.
Over the recent past years, ROS (Robotic Operating System) has become the most widely robotic framework around the world.
ROS is multiplatform, however is predominantly used in Linux, and, for programming, employes C and Python. Yet, several languages which could be used are not covered. The main feature is the active comunity, developing and integrating several sensors and actuators to the system.
Similarly, the group of assistive robotics of the Stat University of Campinas/Brazil (Unicamp) has developed over the few past years an analogous framework, named HTTPThru.
This piece of software enables, through Linux and HTTP, to communicate with drivers of some robots, sensors and actuators.
The main advantage is to overcome the programming language limitation, permiting virtually any programming language to exchange information and control the robotic systems (such as C/C++/C#, Java, Phyton, Matlab, and several others).
Then, the interaction with the robotic devices can be performed in high-level programming environments by Application Programming Interfaces (APIs).
This short course aims to present the two frameworks, ROS and HTTPThru, and to develop the student’s contact with both. To be given in Portuguese.

1) Prof. José Marcos Alonso Alvarez

Universidad de Oviedo, Spain
Presentation Title: GaN HEMT: An Overview of Device Operation and Applications in Power Electronics

Abstract: Power switches based on semiconductor technology have greatly evolved since their first applications in 1960’s decade. Main goals to improve power switches focus on decreasing switching times, series resistance and of course cost. Lower switching times allows for higher operating frequencies of power electronics converters, decreasing both weight and volume and even allowing for integration of power converters in silicon, which is a recent technology known as power system on chip (PSoC). In this milieu, the more promising technologies are based on wide bandgap semiconductors, especially those based on Gallium Nitride (GaN). GaN transistors are high electron mobility transistors (HEMT) that take advantage of the spontaneous formation of a two-dimensional electron gas in the intimate region of two adjacent AlGaN and GaN layers. A very fast and low on-resistance device can be obtained with this structure. The talk will deal with this type of devices in an introductory level by presenting basic GaN FET structures and features, characteristics of commercially available devices, device characterization and modelling and typical applications in power electronics.

2) Prof. Luigi Vanfretti

Royal Institute of Technology (KTH), Estocolmo
Presentation Title: Real-Time and Predictive Monitoring, Analysis and Control of Cyber-Physical Power Systems

Abstract: The uncertainty brought about by renewable energy resources (RES) requires to develop a new understanding on how to monitor, operate, control and protect power transmission networks who will intensively depend of these energy sources.

 Future power systems will increasingly depend on wide-spread sensors, actuators, and computer systems exchanging real-time measurements and control actions through communication networks. To exploit the availability of wide-area time-synchronized measurements and distributed control systems, software and hardware solutions will be ‘in the loop’, transforming the electrical power networks into cyber-physical systems. These solutions need to be developed with a strong foundation in control theory, communication networks, efficient IT, measurement-and-model based analytics (such as model-based design, signal processing and machine learning), embedded systems design and implementation, and power engineering knowledge to enable resilient operation of the future cyber-physical grid (i.e. the “technical” smart grid).

 This talk will explore, through research project examples, concepts, methods and tools enabling a transition towards a smart cyber-physical grid where increased sensors, ICT, analytics and control can be enabled through the development of Wide-Area Monitoring Protection and Control (WAMPAC) applications, which in turn can aid in managing the stringent operation conditions which RES pose to current power transmission grids.

 Furthermore, to develop new real-time data based applications, experimental work needs to be performed. An overview of a real-time hardware-in-the-loop laboratory (SmarTS Lab) created to achieve this goal will be presented. The on-going and future development of “Smart Grid Apps” (software applications) using a measurement-and-model-based data analytics can help in monitoring and controlling large scale power networks is briefly outlined.
