Welcome message from the President of IEEE Power Electronics Society
On behalf of the IEEE Power Electronics Society I warmly welcome you to the third ICDCM
conference, which is held in Matsue, Japan here in 2019. DC micro-grids are evolving very fast
and the level of attendance, submitted papers and also companies who sponsor this conference
clearly indicate this. Our modern society becomes more and more electrified - we have alreadymany examples of DC based grid structure - but as the power electronics technology continuous
its progress, we will see even more - in many autonomous systems, in the transportationelectrification but also as grid structure in rural areas just to mention a few. The tracks at thisconference clearly indicate the areas under development.
The conference has all aspects of a classical conference structure including an interestingsocial programme to - which can be used for professional networking - A special thanks to allvolunteers for this conference and sponsors - without such support - ICDCM would hardly bepossible. And thanks to the general chairman Keiichi Hirose - congratulations for this event.
I wish you all an inspiring and enjoyable ICDCM.

About Matsue Castle
Matsue Castle is a feudal castle in Matsue in Shimane prefecture, Japan. Nicknamed the "black
castle" or "plover castle", it is one of the few remaining medieval castles in Japan – at least of the
few remaining in their original wooden form, and not a modern reconstruction in concrete. The
construction of Matsue Castle began in 1607 andfinished in 1611, under the local lord Horio Yoshiharu.
Most Japanese castles have been damaged or
destroyed by war, earthquakes, or other causes. Sincea large part of their construction was wooden, fire was amajor hazard. Matsue castle was built after the last great
war of feudal Japan, so it never saw a battle. Yet only
some of the walls and the keep exist today.
Matsue Castle, standing on the shores of Shinji Lake,is one of Japan's Three Great Lake Castles. It is also
known as a riverside district.

About Adachi Museum of Art
The Adachi Museum of Art was founded by Adachi
Zenko in 1980 as a way of combining his passions forJapanese art and garden design. He hoped that viewing
the gardens and artwork together would expand peoples'
appreciation and interest in Japanese art.
The Adachi Museum of Art is best known for its award
winning garden. It has been named the best garden in
Japan annually since 2003 by the "Journal of Japanese
Gardening". The garden can be enjoyed at any time of
the year and shows a different character depending on
the season. It can only be viewed from the museum
building. In addition to the gardens, the Adachi Museum of Art also houses a collection of nearly
1300 twentieth century paintings and artworks which are rotated seasonally. There is also apermanent exhibit of paintings by Yokoyama Taikan, as well as a ceramics exhibit.
About Yushien (Banquet venue)
Yushien is located on Daikonjima, a small 12 km islandthat was formed by a volcanic eruption. Up until the 1950s,
Daikonjima enjoyed prosperity through their silkworm
industry, but the island eventually fell into decline and thewomen of the island resorted to traveling around outside
the island selling young peony trees in order to make aliving. Seeing the women like this touched the heart of
Kadowaki Sakae, the creator and first generation owner ofYushien. He decided to create Yushien so that the womenof Daikonjima did not have to leave the island and could attract visitors from all over Japan to see thebeauty of the island’s peonies. 5 years later, Yushien was opened to the public and ever since thegarden has become a highly popular tourist spot, attracting around 300,000 visitors per year.

by Sakura Internet Inc., are not the exception but could minimize the adverse influences.
Sakura Internet Inc., had already introduced a DC power system with 380 VDC distributions andserver racks. This DC power system is connected to a 200kW solar panel, which not only works
on CO2 reduction, but also contributes to reducing power consumption and improving reliability.
In this plenary speech, Mr. Kunihiro Tanaka, founder and president of Sakura Internet Inc., talks
about the results of DC power supply systems that were completely worked during the Hokkaido
blackout, and proves to be the most reliable and stable. The DC power system for data center will
be expanded to not only the ICT sectors but also the smart grid and the community as an essential
power supply infrastructure.
Note: This speech is offered by Japanese-English translation.
Kunihiro Tanaka was born in 1978. He founded “Sakura Internet” for hosting service with startup services in 1996, while studying at National Institute of Technologies, Maizuru College at theage of 18. After limited company, “Inforest” founded in 1998, he became a president andestablished a “Sakura Internet Inc.” the following year. In 2005, it listed on the Tokyo Stock
Exchange Mothers, became listed on the Tokyo Stock Exchange in 2015.

Keynote – 2
Date: May 23, Thursday 9:30 – 10:00, Hall A
Name: Sudip K. Mazumder, Prof. IEEE Fellow, University of Illinois at Chicago, USA
Title: EV Battery Supercharger: Confluence of Advanced Power Electronics and NextGeneration SiC Devices
Summary: Electric vehicles (EVs) are one of the major technological advancements that help in
reducing the dependence on the fossil-fuel-based energy sources. EVs are typically charged
using Level-1 chargers, which are slow and need to be plugged in overnight. Level-1 chargers
operate using 120 V (RMS) single-phase AC available at homes. Level-2 chargers need 240 V(RMS) single-phase input and offer relatively faster charging capabilities but still take relatively
long time to charge the batteries. A long battery charging time limit the operating range of EV andserving time. Recently, the focus has been on DC Level-3 quick charger (DCQC), which typicallyoperates using 480/679 (RMS/peak) V three-phase AC input. Power levels are normally up to
about 60 kW. This results in rapid charging of the EV batteries. Typical time taken to charge to
80% is just 15-30 minutes. However, the current silicon-based power-electronic charger solutions,which are typically transformer and multiple-conversion-stage based, are relatively low on power
density, specific power, peak efficiency, and thermal sustenance. Rapid technologicaladvancements, using integration of SiC technologies and novel EV charger circuit innovations
that reduce architectural and operational complexities, are needed for reduced volume, reduced
weight, lower cost, enhanced reliability, and wide (and hence universal) voltage applicability
thereby yielding greater market penetration and accelerated deployment of EV charging
infrastructure aside from providing a pathway to on-board vehicular integration of the charger athigher power. This keynote will provide a broad outline on the newly-emerging DC battery
supercharger and how it benefits by the confluence of advanced power electronics and SiC
devices.

Tutorial Part-1: DC Microgrids: Architectures, Control and DC/DC Converter
Topologies
Tutorial 1-1
Date: May 20, Monday 9:30 – 10:15, Hall A
Name: Tomislav Dragičević, Associate Professor, Aalborg University, Denmark
Title: DC Microgrids: Applications, Architectures and Control
This part of tutorial aims firstly to shed light on practical design aspects of DC distribution
technology concerning typical power hardware topologies and their suitability for different existingand emerging applications. Moreover, several industrial projects in the area of DC microgrids,
from remote telecom systems to commercial and military shipboards and to DC homes will be
introduced. Following this overview, a systematical control structure for DC microgrids will bepresented and classified into local and coordinated control levels according to the respectivefunctionalities in each level. As opposed to local control which relies only on local measurements,
communication channels between units needs to be made available in order to achieve
coordinated control. In this view, the overall control in DC microgrids, depending on thecommunication topology, can be divided into three basic coordinated control strategies, i.e.
decentralized, centralized and distributed control. These strategies are briefly overviewed, and aseparate application example is presented to clarify each one of them. While, all presented
examples rely on non-isolated DC/DC converter topologies, in many practical DC microgrid
applications, it is worthwhile to have isolated topologies. For this reason, the following two partsof the tutorial explore modeling and control of dual-active bridge (DAB), as one of the mostprominent members of the family of isolated DC/DC converters.
Tomislav Dragičević (S’09-M’13-SM’17) received the M.Sc. and theindustrial Ph.D. degrees in Electrical Engineering from the Faculty ofElectrical Engineering, Zagreb, Croatia, in 2009 and 2013, respectively.
From 2013 until 2016 he has been a Postdoctoral research associate at
Aalborg University, Denmark. From March 2016 he is an Associate
Professor at Aalborg University, Denmark. He made a guest professor
stay at Nottingham University, UK during spring/summer of 2018. His
principal field of interest is overall system design of autonomous and gridconnected DC and AC microgrids, and application of advanced modelingand control concepts to power electronic systems. He has authored andco-authored more than 170 technical papers (more than 65 of them are published in international
journals, mostly IEEE Transactions) in his domain of interest and 8 book chapters and an IET
book in the field of DC microgrids. He serves as an Associate Editor in the IEEE Transactions on
Industrial Electronics, in the IEEE Emerging and Selected Topics in Power Electronics and in the
Industrial Electronic Magazine. Dr. Dragičević is a recipient of a Končar prize for the best industrial

Tutorial 1-2
Date: May 20, Monday 10:15 – 11:00, Hall A
Name: Shuai Shao, Assistant Professor, Zhejiang University, China
Title: Modeling, Modulation, Circulating Current and ZVS-on of a Dual Active Bridge
DC/DC Converter
The second part of the tutorial goes more in detail with regard to Dual active bridge (DAB) dc-dc
converter which is a promising technology for smart grids, energy storage systems andbidirectional electric vehicle on-board chargers due to its attractive features including auto-adjust
bidirectional power flow, wide voltage gain range and ZVS-on capability. In this tutorial, modelingof a DAB is firstly introduced. The inductor current of a DAB is purely ac and its modeling isdifferent from conventional dc converters. Various methods including reduced order model,
improved reduced order model, generalized average model and discrete-time model are
introduced and compared with simulation results. Based on the derived DAB model, the control
of a DAB converter is presented. Feedback control, feedback plus feedforward control andfeedback control based on observer are introduced. Simulation results are given to compare theperformance of these control methods. Some practical issues such as dead time effect, phasedrift and transformer dc offset suppression are also explained. Circulating current and loss of
ZVS-on can decrease DAB conversion efficiency significantly. For the circulating current problem,
this tutorial explains the cause of the circulating current based on the fundamental component
analysis (FCA). Hardware methods to suppress the circulating current are firstly presented. Thenthe PWM plus phase shift control based on FCA and time domain analysis are introduced, andthe optimal phase shift ratios are given to achieve the minimum circulating current. Thesemethods to suppress circulating current are summarized and compared. Next, the ZVS-on of DAB
is discussed. The ZVS-on range of a DAB is firstly derived using fundamental component analysis.
Control methods including PWM plus phase shift and frequency modulation are introduced.
Hardware methods including current-fed DAB, variation of inductance are also explained. Finallyexamples of applications of bidirectional DAB are introduced such as V2G on-board EV charger,
and DC solid state transformer.

Title: A Model predictive control of a DAB converter in DC microgrids on naval vessels
and more electric aircraft
The third part of the tutorial will focus on the control for isolated dc-dc converters which are theenabling technology for the integration of energy storage systems in microgrids on naval vessels
and more electric aircrafts. They present a common feature of galvanic isolation with highfrequency transformer. The existence of the high frequency transformer causes issues inconverter modelling and control. In this tutorial, a Moving Discretized Control Set Model Predictive
Control (MDCS-MPC) tailored for isolated dc-dc converters is presented. This tutorial kicks off byintroducing the concept of the MDCS-MPC. Fixed switching frequency is maintained, enablingeasy passive components design. The proposed MDCS-MPC has a reduced prediction horizon,
which allows low computational burden. The operating principle of the MDCS-MPC is introduced
in development of a cost function that provides stiff voltage regulation. Resonance damping andsampling noise resistance can also be achieved with the cost function. An adaptive step isintroduced to enable fast transition. Assessments on the performance of the proposed MDCSMPC are conducted. Comparisons with other control methods are also provided. Based on the
MDCS-MPC, online optimization is carried out by exploiting the extra degree of freedom in Dual
Phase Shift. The conceptual process of the 2-D optimization is introduced in development of acost function that on one hand regulates the output voltage, on the other hand, minimizes thetransformer peak current. Further extension of the MDCS-MPC to Triple Phase Shift (TPS) is
explained. Due to the limitation on the computational power in standard commercial control
platforms, the optimization is carried out offline aided by artificial neutral network. Conventional
linear control shows limitation under TPS as several operation modes coexist. In contrast, control
parameters in MDCS-MPC are expected to work for all operating modes with salient performance.
Finally, MDCS-MPC is applied for the isolated DC/DC converters for fast system stabilization.
The impedance of the converter is presented by describing function. The mechanism of theinstability is analyzed based on the impedance. A damping term is derived in the cost function for
MDCS-MPC which drastically increases the phase margin.

Tutorial 2-1
Date: May 20, Monday 13:00 – 13:45, Hall A
Name: Nihal Kularatna, Associate Professor, School of Engineering, the University ofWaikato, Hamilton, New Zealand
Title: Supercapacitor Techniques for DC Microgrid Applications
Outline: During the last two decades, electronics industry has seen many commercial versions ofelectrical double layer capacitors (EDLC), which are also known as ultra-capacitors andsupercapacitors, with the aim of complementing or replacing electrochemical batteries. EDLCs
come in capacitance values from 0.2 to 7500 farads, with the limitation of very low DC voltage
ratings from 0.7 V to 4 V. An EDLC gives an approximately one million times larger capacitancecompared to an electrolytic. Recently some SC manufacturers have introduced a novel family of‘supercap-batteries’ where capacitance has gone up to 70,000 F. Compared to conventional
capacitors with large DC voltage ratings, EDLCs offer one to two order greater energy density
and approximately twice the power density.
Supercapacitors can be the basis for non-traditional and novel circuit topologies to achieve:
significantly high energy efficiency in DC-DC converters; surge protection; rapid energy transfer;high density inverters and renewable energy converters with DC-UPS capability. Seminar will
present a discussion on how to develop unique solutions to well-known issues in powerelectronics, with the examples of developing many patented or patent pending SC assisted (SCA)
techniques such as SCA low dropout regulator (SCALDO), SCA surge absorber (SCASA), SCA
temperature modification apparatus (SCATMA), SCA high density inverter (SCAHDI) and SCA
light emitting diodes (SCALED). Industrial applications of these SCA techniques will be discussed
including their application in DC Microgrid area.
Nihal Kularatna is an Associate Professor in the School of Engineering
at the University of Waikato, New Zealand. He won the New ZealandInnovator of the year award (2013). His electronic engineering careerspans 43 years and he is active in research in supercapacitor
applications, power supply topologies, and power conditioning. He has
contributed to over 150 papers and nine reference books. His important
contributions include two IET Electrical Measurement Series books titledModern electronic test & measuring instruments (1996) and Digital andanalogue instrumentation- testing and measurement (2003/2008) andthree Elsevier (USA) titles. His recent research monograph on surge protection systems, titled
Design of Transient Protection Systems, was published by Elsevier in 2018, summarizing hiscommercially oriented research on his SCASA technique. Multiple patents were granted for his
supercapacitor assisted (SCA) circuit topologies. Before migrating to New Zealand in 2002, he
was the CEO of the Arthur C Clarke Institute in Sri Lanka.

Title: Extremely High Safety and Long Cycle life Energy Storage System (ESS)
Abstract: In the ESS market, long cycle life is required during 15 years, and then, safetycharacteristics of ESS has to be remaining at the temperature range of 0~60 ˚C. Long cycle life
can be obtained by employing electrochemically stable cathode such as olivine LiFePO4. Evenby extracting Li from LiFePO4, olivine structure remains stable at fully charged state even at hightemperature range of 40~60 ˚C.
Furthermore, fire propagation of battery module can be controlled by using LiFePO4 cell. If one
cell would explode and fire in the battery module, battery module does not explode and fire. Thishigh safety character is significant in order to illuminate ESS fire incident completely. On thecontrary, in case that battery module propagates, ESS is burnt out completely if one cell explodeand fire. As ESS is using many cells, and operates at -20~60 ˚C, it is very difficult to control ESS
safety issue during 15 years.
Murata have developed high quality LiFePO4 cell, battery module, and extremely high safety
and long cycle life ESS. In this session, we will present on key technologies regarding cycle
performance and safety characteristics, which shall be needed concerning with ESS.

Summary: Hardware-in-the-loop (HIL) real-time simulation is a method that allows testing of
power and energy apparatus, controllers, and fault protection in a meaningful system relevant
environment. Most of the system, however, is modeled on a real-time simulation platform and thedevice(s) under test (DUTs) are interfaced with the rest-of-system (ROS) simulation in order toallow both to interact with each other. In particular, we distinguish between controller HIL (CHIL)
and power HIL (PHIL) as CHIL only requires signal level interfaces between the DOTs and the
ROS simulation, whereas PHIL requires power amplifiers, too. This workshop will introduce thisconcept of HIL, describe applications in various fields of electrical power systems engineering,
including testing of photovoltaic systems for anti-islanding compliance, discuss the latest
developments in high speed real-time simulations, and explain the efforts undertaken by the IEEE
Working Group P2004 which currently develops a “Recommended Practice for HIL”. The
attendees will gain a better understanding of HIL and learn where and how this method is used
for de-risking the integration of new technologies into emerging power systems such as MVDC
systems.
Michael "Mischa" Steurer received a B.S. and M.S. in ElectricalEngineering from the Vienna Technical University in 1994. He received a
PhD in Electrical Engineering from the Swiss Federal Institute ofTechnology in 2001. Since 2001, He is a senior researcher at Florida

Measures against global warming to realize
a decarbonized society, wide-ranging
energy-conservation efforts to improve theglobal environment and transform working
styles, preventing natural disasters like heatwaves and heavy rains in recent years…
Companies today face a host of social
challenges that demand prompt action.

NTT Facilities has supported the NTT
Group’s communications infrastructure andsystems for more than 100 years. What’smore, NTT Facilities leverages its energy
and construction technologies, which it hasdeveloped in a wide range of industries, andworld-leading ICT to offer integrated
services and solutions at the highest level.

“Decarbonization” is a global movement
today, and it is an urgent undertaking for
all companies. We at NTT Facilities arecontributing to the realization of a“decarbonized society” by pursuing not
only energy conservation technologies,
but also ideal ways of utilizing energy,
from energy creation to renewableenergy.

Energy conservation measures today seek to beboth “environment-friendly” and“worker-friendly.” We at NTT Facilities aredeveloping state-of-the-art smart buildings andcomfortable environments for workers by
combining IoT-based energy conservation
technologies and energy creation technologies
like solar power generation.

Facility resources—land andbuildings—are considered to be thefourth base of company management.
With our unique managerial perspective,
we at NTT Facilities maximize total“facility performance” by reducing
operational costs while boosting asset
value.

Data centers that support big data, AI, and IoT
must handle information communication
volume multiplying at an exponential rate. The
challenges of managing data centers include
rising energy costs, swelling data capacity, andcomplexity in operations. We at NTT Facilities
contribute to the solution of these challenges
with comprehensive support, from data center
construction to maintenance.
