Tutorial 2 – Resiliency in smart distribution systems
Tutorial will run in the morning of June 3, 08:30-12:30
Speakers: Dr. Anurag Sharma, Department of Electrical Power Engineering, Newcastle University, Singapore, and Sayonsom Chanda, Power Systems Research Engineer, Idaho National Laboratory, Idaho Falls, USA
Abstract: This tutorial will address the issues and highlight techniques to enable grid resiliency. The resiliency of the grid is not defined only on the basis of its ability to restore the system as soon as possible, but it also includes the ability of the grid to anticipate faults and resist discontinuity of power supply to critical loads. Thus, it is important to first decode the term resiliency for a distribution system and then suggest techniques to quantify and enhance the resiliency of the grid. The task becomes more challenging if distributed energy resources such as distributed generation (DG), battery energy sources (BES), and electric vehicles (EVs) are considered.

1. Definition and Quantification of grid resiliency
In this session, we will discuss industry-wide working definitions of power distribution system resiliency and state-of-the-art approaches being used by industries and utilities world-wide to design and operate resilient distribution systems. We will discuss in great depth means to alleviate stress and vulnerabilities in modern distribution system operation by quantifying resilience of the distribution system in real-time and using it as an optimization parameter. We will also introduce the audience to how the notion of resilience differs from reliability. In particular, we will derive and explain how resilience metrics can be computed in real-time using Choquet Integral, and multi-criteria decision-making methods, such as Analytical Hierarchical Processing. At the end of the tutorial, the audience will be able to have an in-depth understanding of power system resilience, and will be equipped with technical knowledge to implement resilience metrics to operate power distribution systems more efficiently, while dynamically protecting the systems from unforeseen stress or operating conditions imposed due to strong weather events, or cyber-attacks.
2. Enabling grid resiliency
This session will present techniques to enable grid resiliency. Specifically, it will highlight a self-healing technique for smart distribution systems in an uncertain environment, in the presence of various distributed energy resources such as DGs, BES, and EVs. The use and importance of decentralized multi-agent system approach will be discussed due to the time critical decision-making required for this problem.
Tutorial 3 – Application of Wind Generation Systems to Weak Networks – Design Considerations
The tutorial has been cancelled
Speaker: Dr. Rene Rossi, R. Rossi & Associates Consulting Engineers Pty. Limited, Australia
Abstract: The application of wind generation systems throughout the world has been extensive, especially when interconnected to very robust network. Yet the application of wind generation system to weak networks has not been that predominant given the limitations imposed by the network operators, the remoteness of such applications in some cases, stability issues and other limiting factors. In many instances, not enough analysis is done to understand the implications of such installations especially when applied to networks with large industrial loads (unstable loads). Computer models are essential for this analysis.

Tutorial 4 – Control and topologies of modern power electronics converters in renewable energy sources and smart-grids
Tutorial will run in the afternoon of June 3, 13:00 - 17:00
Speaker: Prof. Mariusz Malinowski, Institute of Control and Industrial Electronics, Warsaw University of Technology, Poland
Abstract: This tutorial aims at presenting an introduction on PWM converters for renewable energy sources and smart-grids, that can be more efficient, reliable, cheaper and smart with proper design of converter topology. Furthermore, application and new advanced control and modulation techniques will be explored. This work is motivated by the fact that during the last years, PWM converters have drastically increased their importance on the market of DC-AC, AC-DC and DC-DC conversion. Two technology breakthroughs of the electronic industry enabled this remarkable development:
- the introduction of semiconductors on the market enabled the manufacturing of reliable, robust and low-cost converter modules,
- the introduction of low cost microprocessors (e.g. DSPs) and FPGA for real time applications allowed the successful implementation of complex vector control schemes.
Lately the PWM converters become very important for integration of renewable energy to the distributed energy systems. They offer characteristics like: Maximum Peak Power Tracking (MPPT), excellent control of induction or permanent magnets synchronous generator, a low harmonic distortion of the line currents, a regulation of the power factor, an adjustment and stabilization of the DC-link voltage.
