towards the future of the energy systems
About the Webinars
INESC TEC, through its Centre for Power and Energy Systems and the Energy cluster, has launched the Power and Energy Webinar Series initiative. In each webinar, a researcher from INESC TEC will present and discuss ideas, expected outcomes, or results regarding the energy systems of the future. In some webinars, external speakers will be invited. The expected duration of the webinar is between 45 minutes and 1 hour, depending on the format. Discussion between the speakers and the participants will be held in the last part of each webinar.
Network Reinforcement and Transmission Network Planning
July 7, 3 PM (GMT)
José Nuno Fidalgo,
Associate Professor at Faculty of Engineering at University of Porto and Senior Researcher at INESC TEC
Distribution network reinforcement: how valuable is the investment postponement?
The last decade has witnessed a growing tendency to promote deeper exploitation of power systems infrastructure, postponing investments in networks reinforcement. Smart Grids are expected to offer pervasive monitoring, secure and reliable communication technologies and advanced control schemes. These features will allow better approaches for Demand Response, microgeneration control, EV charging, storage and other energy resources. As so, the scientific literature often proclaims the Smart Grids potential to defer investments in network reinforcement.
The first part of this presentation shows that, although Smart Grids do permit investments postponement, this is usually a bad option in the long term. This illustrated with an algorithm that finds the optimal moment for network reinforcement.
The second part illustrates how to set a practical and cost-effective network reinforcement approach, confirming that better results are obtained when the power system infrastructure is not explored close to its limits.

Transmission Expansion Planning: The new uncertainties challenges
Led by wind farms, hydro and solar PV, the share of renewable energy is growing every year, as well as their impacts related to the seasonalities and climatic conditions, which directly affect the maintenance and operation of the power system. The consequences of unexpected events can be mitigated by a protective umbrella that turns the black swan into a gray swan. Thus, the more interconnected and redundant the grid, the more reliable and secure the energy supply will be to retailers and consumers. From an economic perspective, this solution would certainly require large investments that may not be feasible at some point due to financial constraints. In this way, TEP studies are very important to model the problem as realistically as possible while obtaining technically feasible solutions with the lowest possible investment costs. This study aims to answer the following main research question: How to obtain integrated decisions in long-term transmission expansion planning considering climate resilience?

Luiz Eduardo Oliveira, senior engineer at Siemens
Master of Science in Power Systems from the University of Brasilia (2017), Luiz has SAP ERP HR certification and specialization in Brazilian Payroll (Molga 37). After graduating in 2013, he was a university professor in CEFET-MG (2014). From 2014 to 2016, Luiz worked at Capgemini in the CAIXA+10 project as SAP consultant. Back to engineering, after his Master in Brasilia, Luiz flew to Portugal to pursue his Doctoral Degree in Power Systems. He worked with INESC TEC in the INTEGRID (MVLA and HEMS) and in the V2G project. Actually, Luiz Oliveira is a Senior Engineer on SIEMENS.
