About

I graduated in Electrical Engineering in the Faculty of Engineering of the University of Porto - FEUP (2003), and completed his PhD in Power Systems in November 2008, also in the University of Porto.

I am with the Centre for Power and Energy Systems of INESC TEC since September 2003, being senior researcher since 2009. I am also the “Network Studies and RES & DER Integration” Area leader in the Centre for Power and Energy Systems of INESC TEC since September 2015. In February 2009 I joined the Department of Electrical Engineering of FEUP as Assistant Professor, being involved in the lecturing activities in the Integrated Master in Electrical and Computer Engineering as well as in the Doctoral Programs (Doctoral Program in Sustainable Energy Systems and Doctoral Program in Electrical and Computer Engineering). 

I have been involved (either as a technical leader of research teams or as a Researcher) in several EU-funded projects, namely:

1.      MICROGRIDS: Large Scale Integration of Micro Generation to Low Voltage Grids;

2.      MORE-MICROGRIDS: Advanced Architectures and Control Concepts for More Microgrids;

3.      MERGE: Mobile Energy Resources for Grids of Electricity;

4.      TWENTIES: Transmission system operation with large penetration of Wind and other renewable Electricity sources in Networks by means of innovative Tools and Integrated Energy Solutions;

5.      HYPERBOLE: HYdropower plants PERformance and flexiBle Operation towards Lean integration of new renewable Energies;

6.      EU-SysFLEX: Pan-European system with an efficient coordinated use of flexibilities for the integration of a large share of RES.

I have been also involved in technical consultancy activities regarding wind farms connection to the grid. Additionally, I have been also providing technical consultancy regarding large-scale integration of renewable energy sources in isolated power systems while adressing system dynanmic and transient stability. 

The main domains of my current research activities are related with large scale integration of renewable power sources in isolated and interconnected power systems, power system dynamics and microgrids operation and control.

Abstract
This paper addresses the dynamic stability analysis of an islanded power system regarding the installation of a reversible hydro power plant for increasing renewable energy integration. Being a high-head facility, the hydro power plant consists of separated pumps and turbines (Pelton type). In order to properly support the identification of hydro pumps connection requirements and the technology to be used, different options were taken into consideration, namely: fixed speed pumps coupled to induction machines directly connected to the grid and adjustable speed pumps supplied by a drive system. Extensive numerical simulations of the power system's dynamic behaviour response allowed the evaluation of the hydro power plant's role for the purpose of grid stability conditions. These simulations showed that the high-head hydro power installation provides a marginal contribution to system frequency regulation when explored in turbine operation mode, leading to a reversible power station with a single penstock. Moreover, due to the significant additional system load introduced by the hydro pumping units, the obtained results clearly indicate that supplementary regulation flexibility is required to attend the need of assuring the stable operation of the system in case of critical disturbances such as grid faults. The study case demonstrates that, although the foreseen operation of a reversible hydro power plant creates new security challenges to overcome in an autonomous power system, robust technical solutions can be identified without increasing, from the local system operator's perspective, the operation complexity of the power system. © 2018 Elsevier B.V.

The role of low-voltage-ride-through capability of distributed energy resources for the mitigation of voltage sags in low voltage distribution grids

Abstract
The large scale integration of Distributed Energy Resources (DER) at the Low Voltage (LV) distribution network offers new opportunities for the improvement of power quality and network reliability. Currently, the occurrence of large disturbances at the transmission network causing severe voltage sags at the distribution level could lead to the disconnection of a large share of DER units connected to the LV network, causing a more severe disturbance. In this paper, Low-Voltage-Ride-Through (LVRT) requirements and current support strategies are proposed to mitigate the impact of severe voltage sag at the distribution level for DER units connected to LV network. The impact of adopting the proposed LVRT strategies will be analyzed through simulation and experimentally. A developed in house ESS prototype incorporating the developed LVRT strategies is also presented, and its capacity to comply with the proposed LVRT requirements is demonstrated using an experimental Power-Hardware-in-the-Loop (PHIL) setup. © 2018 Power Systems Computation Conference.

Identification of Dynamic Simulation Models for Variable Speed Pumped Storage Power Plants

Publication
Journal of Physics: Conference Series

Abstract
This paper addresses the identification of reduced order models for variable speed pump-turbine plants, including the representation of the dynamic behaviour of the main components: hydraulic system, turbine governors, electromechanical equipment and power converters. A methodology for the identification of appropriated reduced order models both for turbine and pump operating modes is presented and discussed. The methodological approach consists of three main steps: 1) detailed pumped-storage power plant modelling in SIMSEN; 2) reduced order models identification and 3) specification of test conditions for performance evaluation. © Published under licence by IOP Publishing Ltd.
