I was born in Cinfães, Portugal in 1984. I received the Master’s degree in Electrical and Computers Engineering from the Faculty of Engineering of the University of Porto (FEUP), Portugal, in 2009 with major studies in Electricity Markets. I have been working ever since in the R&D Centre for Power and Energy Systems (CPES) at INESC TEC where I am a researcher. My professional contribute includes participation in consulting projects for Portuguese energy companies and participation in European projects within the networks planning and participation in projects aiming to optimize the operation of power systems.

On a personal level, I am motivated by the challenge. I am a creative and willing to learn person, not forgetting the critical spirit that I always try to preserve.

Dimensioning Studies for Reversible Hydro Power Plants in Portuguese Islands

Fonseca, N; Madureira, A; Lopes, JP; Matos, M;

U.Porto Journal of Engineering

This work is within the scope of set of consultancy studies made for Portuguese islands. It focuses on the integration of Pumped Storage Power in isolated islands. The paper starts to address several power systems circumstances about two Portuguese islands on the energetic level. For each of these islands, an independent examination of the conditions to install a reversible hydro power plant is accomplished. Therefore, the energy volume to be stored due to excess of renewable generation and the ideal power and number of the pumps and turbines to be installed were identified and evaluated for the sake of using the produced energy surplus as to be pumped and later generated. The paper enhances the importance of storing energy in the operation of isolated and small systems with considerable amount of intermittent power resources as well as the conditions for the viability of installing new exploitations of this kind.

This paper presents two contributions developed in the framework of evolvDSO Project to support TSO-DSO cooperation. The Interval Constrained Interval Power Flow (ICPF) tool estimates the flexibility range at primary substations by aggregating the distribution network flexibility. The Sequential Optimal Power Flow (SOPF) tool defines a set of control actions that keep the active and reactive power flow within pre-agreed limits at primary substations level, by integrating different types of flexibility levers. Several study test cases were simulated using data of four real distribution networks from France and Portugal, with different demand/generation profiles and several degrees of flexibility.
