Microgrids – Changing the Way of Thinking Energy Systems
Abstract: A microgrid can be defined
as a part of the grid with elements like distributed energy sources, power
electronics converters, energy storage devices and controllable local loads that
can operate autonomously in islanded mode but also interacting with the main
power network in a controlled, coordinated way. Following the introduction of
distributed control of these elements, cooperative control and hierarchical
control schemes for coordination of power electronics converters in order to
control the power flow and to enhance the power quality will be elaborated.
Different technologies are combined together, such us power converters, control,
communications, optimization, and so on. This way, energy can be generated and
stored near to the consumption points, improving stability and reducing losses
produced by large power lines. In distributed energy systems like microgrids,
multi-agent systems technologies will be presented, including distributed
control.
Previous experiences in the Danish electrical system like the Cell Controller
project used these technologies to balance dispersed energy generation and
consumption. The focus of this presentation will be on the analysis, modelling
and control design of power electronics-based microgrids, as well as power
electronics control and communications. Further, the interconnection of
microgrid clusters will be emphasized as an important step towards utilization
of the smart grid concept. In this talk examples of research and projects in
real sites including conventional islanded systems installed in islands and
rural remote areas, low-voltage distribution systems and DC microgrids for
residential applications and homes electrical vehicle charging stations, ships,
vessels, and ferries, and seaports will be shown. .
Bio: Josep M. Guerrero
(S’01-M’04-SM’08-FM’15) received the B.S. degree in telecommunications
engineering, the M.S. degree in electronics engineering, and the Ph.D. degree in
power electronics from the Technical University of Catalonia, Barcelona, in
1997, 2000 and 2003, respectively. Since 2011, he has been a Full Professor with
the Department of Energy Technology, Aalborg University, Denmark, where he is
responsible for the Microgrid Research Program (www.microgrids.et.aau.dk). From
2014 he is chair Professor in Shandong University; from 2015 he is a
distinguished guest Professor in Hunan University; and from 2016 he is a
visiting professor fellow at Aston University, UK, and a guest Professor at the
Nanjing University of Posts and Telecommunications. From 2019, he became a
Villum Investigator by The Villum Fonden, which supports the Centre for Research
on Microgrids (CROM) at Aalborg University, being Prof. Guerrero the founder and
Director of the same centre.
His research interests is oriented to different microgrid aspects, including
power electronics, distributed energy-storage systems, hierarchical and
cooperative control, energy management systems, smart metering and the internet
of things for AC/DC microgrid clusters and islanded minigrids. Specially focused
on maritime microgrids for electrical ships, vessels, ferries and seaports.
Prof. Guerrero is an Associate Editor for a number of IEEE TRANSACTIONS. He has
published more than 500 journal papers in the fields of microgrids and renewable
energy systems, which are cited more than 40,000 times. He received the best
paper award of the IEEE Transactions on Energy Conversion for the period
2014-2015, and the best paper prize of IEEE-PES in 2015. As well, he received
the best paper award of the Journal of Power Electronics in 2016. During six
consecutive years, from 2014 to 2019, he was awarded by Clarivate Analytics
(former Thomson Reuters) as Highly Cited Researcher. In 2015 he was elevated as
IEEE Fellow for his contributions on “distributed power systems and microgrids.”
