Oral Presentations
    Each speaker of an oral presentation has an available time of 15 minutes (12
minutes for the presentation and 3 minutes for questions) and must be in the session
room 10 minutes before of the beginning of the session for to test the audiovisual
equipment and for to exchange opinions with the Session Chairman. We suggest that
the speakers of one oral presentation prepare their material in Power Point.

Poster Presentations
    The posters must be numbered, on the up left corner, with the number of the paper
and it will be put, about 15 minutes before of the beginning of the session, on the pin
board that you previously can chose and it must be take off 15 minutes after of the end
of the session. The author(s) must be stay near the poster during the 45 minutes of the
session duration for to answer all the questions that the audience or the chairmen
could formulate. The maximum available surface for each poster will be 1000 mm x
2500 mm (width x high). You must select your poster size take into account this
maximum available surface (Perhaps an A0 size, 841×1189 mm (width x high), could
be appropriate). Put on the pin board separated sheets of the paper are not allowed.

    On behalf of the International Scientific Committee, Steering Committee and the
Organising Committee of the ICREPQ’20 and take into account their eminent position
in the world of science we have selected 37 session chairmen. It is an honour for us
their collaboration for to chair the sessions of ICREPQ’20 and their contribution would
be greatly appreciated. We wish to express our warmest thanks.
    Traditionally the Chairmen of each Session are independent in organising the
Session. Nevertheless it is of special importance that the different session chairmen
prepare some questions about the papers of their session in order to get a more
dynamic one. Furthermore we expect of the session chairmen the following:

Plenary sessions
    Each plenary session should not exceed 45 minutes including presentation and
discussion, (35 minutes for presentation and 10 minutes for questions).

Oral sessions
   Each oral paper presentation should not exceed 15 minutes including presentation
and discussion, (12 minutes for presentation and 3 minutes for questions).

Poster sessions
    The author(s) of a poster presentation must be stay near to their poster during the
45 minutes of the session duration and in order to get a more dynamic session it is
important that along this period of time each of the chairmen of the poster
sessions formulate questions to the authors and check that all is OK. The chairmen of
each of the poster sessions file up one sheet, with punctuations for each of the
presented poster in that session and then, take into account these evaluations, the
Organizers will deliver during the Closing Session one silver plate and one diploma to
the three best posters selected.

   All the papers presented in the conference will be included in the "Renewable
Energy and Power Quality Journal (RE&PQJ)" with ISSN: 2172-038X and the
CrosRef DOI that will have the format: The
RE&PQJ was accepted by SCOPUS for the indexing process.

 PL1. "Wind generation in weak systems", by Prof. Luis Rouco
                    Universidad Pontificia Comillas. Madrid, Spain

Weak systems are characterized by low short circuit ratio and/or low inertia. Wind generation
face problems of different nature when connecting to weak systems. The question from the view
point of a wind generator manufacturer is to squeeze the generator controls to maximize wind
generation in a given point of connection. Several phenomena and issues will be discussed:
subsynchronous resonance, harmonic amplification, voltage stability and controller interaction.

This contribution will describe methods and tools developed in research projects for wind
generation equipment manufacturers.

PL2. "New trends in electrolyte materials for solid batteries
operating at ambient temperature" by Dr. Claudio Gerbaldi,
GAME Lab, Department of Applied Science and Technology, Politecnico di
Torino, Italy.

 The always increasing role of smart technology in modern society requires the development of
advanced energy storage systems, which can be used in portable electronic devices as well as
in electric and hybrid/electric vehicles and in large stationary storage systems. In this scenario,
lithium-ion batteries represent the mostly efficient and widespreadly exploited technology at
present. However, especially for applications where safety and low cost are essential
requirements, alternative technologies such as Na-ion batteries and/or alternative post-Li
systems are being intensively investigated.

This contribution will provide an overview of the recent trends regarding the development of
highly ionic conductive crosslinked polymer electrolytes with wide electrochemical stability,
mechanical properties for safe and aging resistant lithium- and/or sodium-based batteries
operating at ambient temperature. Noteworthy, the GAME Lab focuses its research activity on
the study and development of innovative, high performance and low environmental impact
materials through the use and optimization of original, clean, simple, low cost preparation
procedures easily scalable at an industrial level.

PL3. "Transition to Renewable Energies: A Reality Check" , by
Prof. Marcel Lacroix, Université de Sherbrooke, Canada.
 The transition to renewable energies (REs) appears to be the way towards a more sustainable
world. The deployment of REs should alleviate our dependence on fossil fuels and abate the
emission of greenhouse gases. But History and fundamental scientific principles reveal that this
energy transition will be far more difficult than anticipated. Ten inescapable realities impede it.
These barriers are: (1) the magnitude of the energy shift and its time scale; (2) the intermittency
of energy supply; (3) the energy storage; (4) the deployment of smart grids; (5) the availability of
strategic minerals; (6) the geography; (7) the energy density; (8) the power density; (9) the
energy return on investment; and (10) the implementation of energy programs and policies. A
thorough examination of these realities shows that REs cannot meet our present needs. The
challenge is not to adapt REs to the world but to adapt the world to REs. The question then is to
determine whether or not the world is ready to embark on such an ambitious journey.

PL4. "How Copper Contributes to Sustainable Mobility", by Dr.
Fernando Nuño. European Copper Institute, Spain

Several analysis predict that by 2040, about 60% of global new passenger vehicle sales will be
EVs, and these vehicles will then make up 30% of the global passenger vehicle fleet. Europe is
expected to become the second largest market for EVs in the 2020s, behind China. This brings
up concerns as to whether there are actually enough resources to meet this growing demand
and to enable the high uptake of EVs in the coming decades. The availability of copper will be
presented and put in perspective with other raw materials such as rare earth elements. High
performance motor design without rare earth permanent magnets is feasible: the ReFreeDrive
project has tackled this challenge. Its main results and a comparison with permanent magnet
benchmarks will be presented.

Fusion" by Dr. Antonio Manuel Peña-García,
                              Peña         University of Granada, Spain

Nuclear Fusion has been one of the golden dreams of Mankind for ages. However, the
successful control and profit from the energy produced in Nuclear Fusion reactions is still far
away to be a reality. There are several reasons for this delay with respect to Nuclear Fission, a
process that has been controlled for many years and powers our houses, factories and
installations everyday. Among the main difficulties to profit from Nuclear Fusion, we find the
control of plasmas at temperatures above 100MºC, and protecting the installation from the
exceeding neutrons. In this complex framework, the International Fusion Materials Irradiation
Facility (IFMIF) - DEMO-Oriented
                            Oriented Neutron Source (DONES), to be installed in Granada
(Spain), is the largest project of the Scientific Community to test the materials that can
accurately stop these neutrons without damaging fusion reactors, and a real hope to definitively
control Fusion and produce high amounts of cleaner energy.

"Application of neural networks to determine the customer
connectivity basedd on smart meters"
Panelist: Mr. Adolfo Carmona Pardo,
                             Pardo Ingelectus.
Abstract: Along with the massive installation of Smart Meters in the distribution grid, new
applications, e.g. state estimation, have been developed in order to improve the operation of the
electrical network. Such applications require a faithful knowledge of the network  n        topology,
specifically the feeder and phase where the customers are connected to. Classical solutions for
this complex combinatorial problem usually fail in such mission. Fortunately, with the
development of artificial intelligence techniques, such as machine learning through neural
networks, this kind of problems can be solved much more efficiently. This works shows the
results of applying, to different currently-operating
                                  currently operating distribution grids, artificial neural networks
which discover the customer connectivity
                              connectivity to the network using smart meter measurements.

                           Rubén Carmona Pardo received B.E. degree in energy
                           engineering and M.Sc. degree in advanced analytics on big data,

 Ensemble Forecasting for Distributed Energy Integration"
Panelist: Catalina Gómez-Quiles,
                   Gómez         University of Seville

Abstract: Modern power systems, embedding ubiquitous distributed energy resources, such as
electric vehicles and storage systems, increasingly need to resort to advanced forecasting
techniques, from generation to demand. In this context, the accuracy of the results is generally
proportional to the benefits for the involved utilities. This has led the stakeholders to test and
compare different prediction techniques in order to identify the most accurate one. An
alternative approach, consisting of an ensemble method which       which dynamically weights all
algorithms over time, is presented and discussed. Tests with actual time series related to
generation and demand have shown improvements in the mean and the standard deviation of
the prediction errors.

"Wind Power Forecasting using Light Gradient Boosting Machine"
by Prof . Xiao-Ping Zhang, University of Birmingham, UK
Abstract: With increasing wind farm penetration, the accuracy of wind power forecasting is of
great interest to the power grid operations due to its stochastic and intermittent nature.
Conventional wind power forecasting method, including both physical method and statistical
method, rely on a numerical weather prediction model. The accuracy of the prediction highly
depends on meteorological elements and it has high computational demand. More recently,
artificial intelligence or machine learning type of prediction models become more and more
developed. In this paper, a light gradient boosting machine based wind power forecasting model
is proposed. The correlation between reference wind mast (RWM) data and wind farm output
power is analyzed. And then the wind power output data is clustered into different groups based
on the Pearson correlation coefficient. Wind power forecasting is then developed through the
light gradient boosting machine within each cluster. The performance of the proposed method is
evaluated against data from a Spanish wind farm Sotavento Galicia.

"Augmented Simulators with AI" by Antoine Marot, R&D engineer
at RTE (Reseau de Transport d’Electricité), France.

Abstract: Transporting electricity across states, countries, or continents is vital to modern
societies. We take for granted that electricity is available to use at all time, but reliably managing
power grids and in particular avoiding ”blackouts” (catastrophic cascading failures) is a difficult
problem requiring skilled engineer controlling operation at all times. With the advent of
renewable energies and the globalization of electricity markets, the problem is increasing in
complexity. In this context, there are opportunities for neural networks and machine learning
methods to help automating the system. The contributions of neural networks can range from
replacing existing physical simulators of the grid by faster neural network proxies, to suggesting
preventive or curative actions to protect lines from over-heating, by rebalancing the flow in the
power grid. The latter problem may be amenable to reinforcement learning. We will compare
two neural network approaches that we developed to speed up power flow computations. The
first one, the LEAP net (LatentEncoding of Atypical Perturbation) implements a form of transfer
learning, permitting to train on a few source domains (grid topology perturbations), then
generalize to new target domains (combinations of perturbations), without learning on any
example of that domain. We evaluate the viability of this technique to rapidly assess curative
actions that human operators take in emergency situations, using real historical data, from the
French high voltage power grid. The second one, the Graph Neural Solver (GNS) overcomes
the limitation of the LEAP net to work in the vicinity of a fixed grid topology by implementing an
iterative approximation of the physics equations. Finally, to go beyond the simple prediction of
flows and move towards assisting operators to control the grid, we present the competition
program ”learning to run a power network”, of which a first edition ran this year as part of the
IJCNN competition program. More information at website:

                             introduce artificial intelligence at every level of the company. He
                             previously lead a team of researchers on a groundbreaking project
                             called Apogee that aims at building a personal assistant for control
                             room operators, in contrast of their always growing fragmented
                             multi-applications with multi-screen working environment today. He
                             owns a double master degree in Engineering from Stanford and
                             Ecole Centrale de Paris with specific interests in both machine
                             learning and the field of energy. After interning at Tesla Motors, he
                             joined RTE on the Apogee project more than 5 years ago in Paris
                             and is looking forward to building new fruitful research collaborati-
ons, in addition to the existing ones with INRIA (the top AI research lab in France), to bring
novel AI solutions to build the smart grid of the future. He recently co-authored many papers
and gave several talks at AI Conferences, such as the openingkeynote at IJCNN 2019.
However, it appears that an artificial intelligence for power systems community needs to be
reinforced to make faster progress. He is eager to contribute building such a community.
Opening challenges such as the "Learning to run a power grid" challenge to wider communities
is one more step to move forward into that direction.

"Self-learning Autonomous Control for Power Systems
Powered by Deep Reinforcement Learning", by Dr. Di Shi, AI &
System Analytics Group at GEIRI North America (GEIRINA), USA.
Abstract: Power systems are facing grand challenges from increasing dynamics and
stochastics from both the generation and the demand sides. This has caused great difficulty in
designing and implementing optimal control for the grid in real time. Tremendous efforts have
been spent in the past on computational methods and advanced modeling techniques that
provide faster and better situational awareness, based on measurements from advanced grid
sensors, PMU as an example. However, as grid operators are heavily involved in the decision-

making process, the entire procedure has not been made fully automated, limiting the potential
of such applications. That is, not only does the ‘grid’ need to perceive faster, it also needs to
think and act faster. Towards this end, sub-second autonomous control schemes need to be
developed. Over the past years, the AI & System Analytics Group at GEIRI North America has
built up an autonomous grid dispatch and control platform using deep reinforcement learning,
the Grid Mind. Recently the Grid Mind framework has been implemented at one of the biggest
provincial power systems in China. This talk will summarize this developmental effort and
lessons learnt from system deployment and validation while focusing on the key technologies
utilized for the Grid Mind framework.

"Post-Disturbance Maximum Frequency Excursion Prediction
Using Convolutional Neural Network" by Prof. Xiaoru Wang
School of Electrical Engineering of Southwest Jiaotong University, China.

Abstract: The significant imbalance between power generation and load caused by severe
disturbance may make the power system unable to maintain a steady frequency. If the post-
disturbance maximum frequency excursion can be predicted and emergency controls are
appropriately taken, the risk of frequency instability will be greatly reduced. In this paper, a
predictive algorithm for post-disturbance maximum frequency excursion is proposed based on
convolutional neural network (CNN) . The operation data before and immediately after
disturbance is used to construct the input tensor data of CNN, with the dynamic frequency
features of the power system after the disturbance as the output. The operation data of the
power system such as generators unbalanced power has spatial distribution characteristics.
The electrical distance is presented to describe the spatial correlation of power system nodes,
and the t-SNE dimensionality reduction algorithm is used to map the high-dimensional distance
information of nodes to the 2-D plane, thereby constructing the CNN input tensor to reflect
spatial distribution of nodes operation data on 2-D plane. The CNN with deep network structure
and local connectivity characteristics is adopted and the network parameters are trained by
utilizing the backpropagation-gradient descent algorithm. The case study results on an
improved IEEE 39-node system and an actual power grid in USA shows that the proposed
method can predict the lowest frequency of power system after the disturbance accurately and

"AI for Real-Time Bulk Power System Steability Estimation" by
Dr. Yilu Liu, University of Tennessee, USA
Abstract: This talk will discuss the work performed for US department of energy in using
artificial intelligence to estimate power system transiemt steability, small signal steability and
frequency steability. The input to the AI engine is system dispatch and the results will be critical
clearing time, frequency nadir for a given genertor trip size and thei nter-area oscillation
damping ratio. The advantage of this AI approach is to reduce dynamic simulation time to
achieve real-time stability predition for a given disapch. Real-time estimation can not be
achieved if using the standard bulk power system dynamic tool such as TSAT due to the large
size of the bulk power grid such as the US eastern interconnection and continental europen
