About

João A. Peças Lopes (PhD) is Full Professor (Professor Catedrático) at the Faculty of Engineering of Porto University, where he teaches in the graduation and post-graduation areas.

Was for 7 years Director of the Sustainable Energy Systems PhD program at FEUP and Director of Advanced course on Sustainable Energy Systems also at FEUP.
He is Director/Member of the Board of INESC TEC.

He is Vice-Presidente of the board of the Portuguese Association for Electric Vehicles.

Prof. Peças Lopes was responsible by INESC Porto activities in several EU financed research projects, namely the project - MICROGRIDS - Large Scale Integration of Micro Generation to Low Voltage Grids  and MORE_MICROGRIDS -  Advanced Architectures and Control Concepts for More Microgrids and MERGE - Mobile Energy Resources for Grids of Electricity.

He supervised several consulting projects related with the impact analysis of the connection of wind parks in the electrical grids of Madeira, Azores,  Sal, S. Vicente and S. Tiago, in the Republic of Cabo Verde. He was the responsible for several consultancy projects related with the electrical grid impact resulting from the connection of large wind parks in Portugal.

He was also responsible for the definition of technical rules for the integration of wind power in Brazil. He coordinated also consultancy studies for the Hungarian Regulator regarding the evaluation of the integration of wind power in Hungary. He coordinates the participation of INESC Porto in the InovGrid project.

He was also the Chair of the Selection Committee of the public tender that decided about the integration of 1800 MW of wind generation in Portugal, launched by the Portuguese government in 2005.

He was member of the Executive board of the EES/UETP consortium and Chair of its course program committee.

He has served as research project evaluator for the European Commission and for governmental science organizations in Portugal, France, Italy, Greece, Finland, Danemark and Ireland.

He was for more than 4 years one of the coordinators of INESC Porto Power System Unit.

He is co-editor of the (SEGAN) Sustainable Energy Grids and Networks journal.

His main domains of research are presently related with large scale integration of renewable power sources in power systems (namely wind generation), power system dynamics, microgrids, smartmetering and integration of electric vehicles in electrical grids.

In 2012 he received the CIGRE Technical Committee Award in recogmition of his outstanding contribution to the work of the Study Committee C6 – Distribution Systems and Dispersed Generation.

Prof. Peças Lopes is an IEEE Fellow
He is member of the Power Systems Dynamic Performance Committee of the IEEE PES.

Wind variability mitigation using multi-energy systems

Abstract
Around the world, there is a great concern with the emission of greenhouse gases, creating great interest in turning the energy systems more sustainable. Multi-energy systems are considered as a potential solution to help to this cause and in recent years, it has gained much attention from both research and industry. In this paper, an optimization model is proposed to use the flexibility of multi-energy systems to mitigate the uncertainty associated with wind generation. The differences between the flexibility provided by multi-energy systems and electrical storage systems in the network were studied. The results prove that the flexibility of the multi-energy systems can benefit the system in several aspects and provide insights on which is the best approach to take full advantage of renewable resources even when a high degree of uncertainty is present. © 2019 Elsevier Ltd

Long-Term Impact Evaluation of Advanced Under Frequency Load Shedding Schemes on Distribution Systems with DG Islanded Operation

Authors

Publication
IEEE Transactions on Smart Grid

Abstract
This paper presents a long-term impact evaluation algorithm to assess advanced under frequency load shedding (UFLS) schemes on distribution systems with intentional islanding of distributed generation (DG). The algorithm is based on a combined discrete-continuous simulation (CDCS) model which is utilized to verify the effect of the schemes on reliability indices such as the System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI) and Energy Not Supplied (ENS). Moreover, a Polynomial Neural Network (PNN)-based approach to advanced load shedding is implemented to support DG islanding in order to illustrate the applicability of the evaluation. Simulation results highlight the long-term effect of employing UFLS to support intentional islanding of DG using an actual network from the South of Brazil. IEEE
