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.

Contribution of variable-speed pump hydro storage for power system dynamic performance

Authors
Silva, B; Moreira, C;

Publication
Journal of Physics: Conference Series

Abstract
This paper presents the study of variable-speed Pump Storage Powerplant (PSP) in the Portuguese power system. It evaluates the progressive integration in three major locations and compares the power system performance following a severe fault event with consequent disconnection of non-Fault Ride-through (FRT) compliant Wind Farms (WF). To achieve such objective, a frequency responsive model was developed in PSS/E and was further used to substitute existing fixed-speed PSP. The results allow identifying a clear enhancement on the power system performance by the presence of frequency responsive variable-speed PSP, especially for the scenario presented, with high level of renewables integration. © Published under licence by IOP Publishing Ltd.

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

Authors
Moreira, C; Fulgencio, N; Silva, B; Nicolet, C; Béguin, A;

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.

Integration of Variable Speed Pumped Hydro Storage in Automatic Generation Control Systems

Publication
Journal of Physics: Conference Series

Abstract
Pumped storage power (PSP) plants are expected to be an important player in modern electrical power systems when dealing with increasing shares of new renewable energies (NRE) such as solar or wind power. The massive penetration of NRE and consequent replacement of conventional synchronous units will significantly affect the controllability of the system. In order to evaluate the capability of variable speed PSP plants participation in the frequency restoration reserve (FRR) provision, taking into account the expected performance in terms of improved ramp response capability, a comparison with conventional hydro units is presented. In order to address this issue, a three area test network was considered, as well as the corresponding automatic generation control (AGC) systems, being responsible for re-dispatching the generation units to re-establish power interchange between areas as well as the system nominal frequency. The main issue under analysis in this paper is related to the benefits of the fast response of variable speed PSP with respect to its capability of providing fast power balancing in a control area. © Published under licence by IOP Publishing Ltd.

Abstract
A distinctive characteristic of a Microgrid (MG) system is related to the ability of operating autonomously. However, the stability of the system relies in storage and generation availability, providing frequency and voltage regulation. Considering the deployment of distributed storage units in the Low Voltage network and of smart metering infrastructures, this paper presents an online tool for promoting an effective coordination of MG flexible resources in order ensure a secure autonomous operation and maximize the time that the MG is able to operate islanded from the main grid. The tool determines a priori an emergency operation plan for the next hours, based on load and microgeneration forecasting. The limited energy capacity of the distributed storage units participating in MG control is also considered.

On the Profitability of Variable Speed Pump-Storage-Power in Frequency Restoration Reserve

Abstract
The increase penetration of renewable energy sources (RES) into the European power system has introduced a significant amount of variability and uncertainty in the generation profiles raising the needs for ancillary services as well as other tools like demand response, improved generation forecasting techniques and changes to the market design. While RES is able to replace energy produced by the traditional centralized generation, it cannot displace its capacity in terms of ancillary services provided. Therefore, centralized generation capacity must be retained to perform this function leading to over-capacity issues and underutilisation of the assets. Large-scale reversible hydro power plants represent the majority of the storage solution installed in the power system. This technology comes with high investments costs, hence the constant search for methods to increase and diversify the sources of revenue. Traditional fixed speed pump storage units typically operate in the day-ahead market to perform price arbitrage and, in some specific cases, provide downward replacement reserve (RR). Variable speed pump storage can not only participate in RR but also contribute to FRR, given their ability to control its operating point in pumping mode. This work does an extended analysis of a complete bidding strategy for Pumped Storage Power, enhancing the economic advantages of variable speed pump units in comparison with fixed ones. © Published under licence by IOP Publishing Ltd.
