Tutorial I

5G Opens the Door for Energy Harvesting (EH) in Telco Applications

Presenter: Brian Zahnstecher, PowerRox, USA
Time: Sunday 22 October, 9.00am-12.30pm (subject to change)
Duration: 3 hours (in two 1.5hr sessions)

Paradigm shifts in critical network aspects such as power electronics and power utilization are required to enable 5G. This tutorial looks into one of the most interesting, yet highly underappreciated, opportunities in 5G power…energy harvesting (EH). EH is commonly perceived to be only useful for very low power applications and not applicable to telecom infrastructure applications. This tutorial will not only help to dispel these perceptions, but also help open the eyes of attendees to applications that they might not have otherwise thought were possible and/or applicable to telco applications (with a special focus on 5G).

This Tutorial will:

  • provide an overview of energy harvesting sources – kinetic, thermal, RF, piezoelectric, photovoltaic, etc.
  • review the practical power electronics solutions to harvest these energy sources.
  • demonstrate how to scale EH technologies from mW to more usable power levels.
  • discover how EH is applicable to telecom and data centers and consider case studies of how to apply EH, with a special focus on 5G.
  • discuss methodologies for achieving a key goal of battery supplementation and eventual mitigation.

This Tutorial is intended for Design Engineers, Program Managers, Data Center Architects, Data Center Managers, & Marketing/Sales Personnel associated with the power supply and/or telecommunications industries.

Tutorial II

Power Converters for Energy Storage Applications
Analysis and Design From Theory to Practice

Presenter: Dr Petar J. Grbović, Power Conversion Technologies Lab (PCTL), HUAWEI Technologies Dusseldorf GmbH, Center of Power Electronics and Drives (C-PED), Roma TRE University, Italy.
Time: Sunday 22 October, 9.00am-12.30pm (subject to change)
Duration: 3 hours (in two 1.5 hr parts)

Power electronics and static power converters play a significant role in industrial applications.  Increasingly, many applications demand energy storage, and an interface ac/dc or dc/dc power converter between the energy storage device and the power system is required.  There are a number of energy storage technologies available and the choice of technology influences the design parameters of the interface converter.  This tutorial examines the converter design process in the light of the characteristics of various energy storage technology options with a focus on ICT energy systems.

The tutorial is divided into two 1.5 hour sessions.  In a broad sense, the first session is the 'energy storage side', and will cover the increasing demand for applications utilizing energy storage, and includes a particular focus on electrochemical batteries and ultra-capacitors.  The second session will cover aspects of interface converter design, different architectures and control strategies, and includes case studies and design examples relevant power systems in ICT energy infrastructure.

The Tutorial content is:-

  • The fundamentals of static power conversion
  • Energy storage devices (batteries and ultra-capacitors),
  • Power conversion & energy storage applications
  • Analysis, sizing and selection of energy storage modules
  • DC/DC interface power converters
  • AC/DC power converts
  • Control of energy storage interface power converters
  • Design case studies

This tutorial is aimed at power electronics engineers, professionals and graduate students who want to improve their knowledge and understanding of advanced energy storage devices, interface converters, and their application in power conversion used in ICT energy infrastructure.

Tutorial III

Base transceiver cooling and thermal energy storage for energy management

Presenter: Dr Ehsan Haghighi, Northvolt AB, Sweden
Time: Sunday 22 October, 1.30pm-5pm (subject to change)
Duration: 3 hours (in two 1.5 hr sessions)

The global growth in mobile (cellular) communications continues to see a proliferation of base transceiver stations (BTS) across large geographical footprints.  As the power consumption of the equipment within the BTS enclosure increases to meet communications bandwidths, there is a corresponding demand for more cooling, and this in turn, the need for improved energy management to limit rising cooling costs.  There are various design approaches and physical techniques that can be applied to the thermal management of the BTS.  This tutorial takes a critical look at various design solutions and compares the effectiveness of particular thermal control and management strategies.

Attendees of this tutorial will learn and explore:

  • Why is cooling of a BTS important
  • A BTS energy model
  • Typical strategies and different cooling solutions
  • Concepts associated with free air cooling
  • Balancing reliability against humidity, temperature and dust
  • Design examples and case studies.

This tutorial is aimed at engineering practitioners, particularly telecom infrastructure designers, and infrastructure owners and operators who what to better appreciate the science behind BTS cooling and learn how energy management approaches can help to reduce equipment heat-loading and cooling cost.

Tutorial IV

Solar & hybrid design for Communications Energy Systems (on - & off-grid)

Co-Presenters: Cal Lahteenmaa, Vertiv Ordonez, David Wilson, Vertiv Co
Time: Sunday 22 October, 1.30pm-5pm (subject to change)
Duration: 3 hours (in two 1.5 hr sessions)

Highly-reliable solar-powered telecommunications infrastructure has a long history in Australia, and there are many examples of solar-powered telecom infrastructure to provide services to remote populations throughout the world.  As communications networks grow there is increasing use of renewable and hybrid energy systems more generally – that is both on and off-grid - to offset fossil-fuel energy costs.  This tutorial will cover a range of material directly associated with designing solar and hybrid energy systems of power both on-grid and off-grid communications systems.  Content will include a overview of rural and urban comms systems and how to understand hybrid opportunities.

Attendees of this tutorial will learn aspects of:-

  • Technology Elements & Selection
    • Solar Panels, Wind Turbines, Generators, Converters & Rectifiers, Enclosures
    • Energy Storage Technologies suited for Hybrids
  • Site Conditions & Environmental Conditions
    • Solar & Wind Calculations
  • Electrical Protection & Safety
  • Maintenance / Operations
    • Monitoring & Control of Hybrid System
    • Performance measurements
  • Return on Investment / Total Cost of Ownership considerations

This tutorial is suitable for infrastructure designers, infrastructure owners and operators, and engineering and professional services practitioners keen to learn or update their technical knowledge of on- and off-grid solar PV and hybrid renewable plant for ICT energy systems.
