Tutorial T1: Increasing the hosting capacity of the grid

Tuesday 26 September 2017 – full day

Organiser: Prof. Math Bollen, Luleå University of Technology, Skellefteå, Sweden

Speakers: Math Bollen (Luleå University of Technology, Skellefteå, Sweden), Fainan Hassan (Turbo Power Systems, UK)

Abstract: The hosting capacity of the grid is the highest amount of new production or consumption that can be connected without endangering the reliability or voltage quality of other customers. It is the basis of a systematic and transparent method for quantifying and communicating the impact of for example renewable electricity production on the grid. Hosting capacity calculations have been performed for a range of phenomena, from overvoltage and unbalance in low-voltage grids to frequency stability in large transmission grids. The hosting capacity concept is also very suitable for comparing different methods improving the ability of the grid to accept renewable electricity production.

In this tutorial the hosting capacity concept will be introduced and examples of calculations will be given. The limitation of calculations and data collection will be discussed in this context. The majority of the tutorial will treat different methods for increasing the hosting capacity. After a brief presentation of classical methods, three smart-grid methods will be discussed: curtailment of production and consumption; power-electronic solutions with the network user (e.g. voltage and frequency control with distributed generation); and power-electronic solutions in the grid (e.g. soft open points and dynamic voltage regulators).

Practical case studies where network users have the potential to provide additional ancillary services to the grid operator through the control of the power electronics interfaces for distributed generation and microgrids will be discussed. Additionally, the opportunities and challenges for providing cost effective solutions using power electronics based equipment in the medium and low voltage grids will be explored in the light of trial results of practical deployments in the UK where three different methods have been installed and compared for increased hosting capacity of congested networks.

Tutorial T2: Energy Internet: Concepts and Key Technologies

Tuesday 26 September 2017 – morning

Organiser: Prof. Yan Zhang, Department of Informatics, University of Oslo, Norway

Speaker: Prof. Yan Zhang, Department of Informatics, University of Oslo, Norway

Abstract: Energy Internet (or Internet of Energy, Energy Informatics) is a vision of future power systems, which will achieve highly efficient interconnection among various types of energy resources, storages, and loads and enable ubiquitous energy sharing on a large scale. The realization of Energy Internet requires deep integration of Internet of Things into smart energy systems.
In this tutorial, we will explain Energy Internet basic concepts, key enabling technologies, and our recent research results. We will first introduce the concepts and main architectures related to Energy Internet. Then, we will discuss on how state-of-the-art information technologies (e.g., cloud cmputing, software defined networking) can be exploited in smart energy networks. Further, we will focus on energy trading and present on how game theory can be used to model and analyze energy trading problems. Demand response management, as a key enabling technology, will be explained to balance and shape the electricity demand and supply. Finally, we will present Internet of Things for electric vehicles and Vehicle-to-Grid, e.g., smart charging schemes and new energy sharing scenarios.

Organiser: Patrick Glauner, Interdisciplinary Centre for Security, Reliability and Trust, University of Luxembourg

Speakers: Patrick Glauner, Jorge Augusto Meira, Radu State (Interdisciplinary Centre for Security, Reliability and Trust, University of Luxembourg), Rui Mano (Choice Technologies Holding, Luxembourg)

Abstract: Electricity losses are a frequently appearing problem in power grids. Non-technical losses (NTL) appear during distribution and include, but are not limited to, the following causes: Meter tampering in order to record lower consumptions, bypassing meters by rigging lines from the power source, arranged false meter readings by bribing meter readers, faulty or broken meters, un-metered supply, technical and human errors in meter readings, data processing and billing. NTLs are also reported to range up to 40% of the total electricity distributed in countries such as Brazil, India, Malaysia or Lebanon. This is an introductory level course to discuss how to predict if a customer causes a NTL. In the last years, employing data analytics methods such as data mining and machine learning have evolved as the primary direction to solve this problem. This course will compare and contrast dierent approaches reported in the literature. Practical case studies on real data sets will be included. Therefore, attendees will not only understand, but rather experience the challenges of NTL detection and learn how these challenges could be solved in the coming years.

Special requirements: Attendees should bring a laptop.

PES Awards nomination for all Awards will have same start and end dates to nominate peers.  The on-line submission starts in mid-September 2017, for the class of 2018, and will be aligned closely with the IEEE process.

As the on-line process opens opportunity for broader membership participation, some background on PES Awards will be covered.  At this Workshop, attendees will have opportunity to learn about history and the types of Awards, Awards web site enhancements with latest information and critical dates, nomination process and demo for hands on step-by-step learning, saving an incomplete nomination, getting print out, or to listen to the presenters and participate in the Q & A.   An overview of effective nomination will also be reviewed in brief.

There will be ample opportunity to review timeline for nominating a colleague, ask some of the administrative questions related to the Awards nomination such as qualifications, references, endorsements, or to provide feedback as the instructors step through the new nomination form.  On-line nomination provides a much greater participation opportunity.  Your feedback supports the process become more efficient to recognize membership and colleagues.

Abstract:

A Smart Metering Infrastructure (SMI) aims at measuring, collecting and post-processing data about the energy usage in smart grid scenarios. Resulting analysis can provide detailed information on the status of the distribution network improving its maintenance. This analysis can also help in planning future intervention in the network, such as the integration of renewable sources and storage systems.
