About

Nuno Fulgêncio has finished his Integrated Master in Electrical and Computers Engineering in 2013, at the Faculty of Engineering of the University of Porto, opting to focus his studies in the field of Energy. In the beginning of 2014 he has joined the INESC TEC team (Center of Power and Energy Systems) as a researcher. Since this time, he has developed work in the area of power systems’ stability studies, mainly through the development and implementation of dynamic models. As of 2015, he joined the Doctoral Program in Electrical and Computers Engineering, in the same faculty.

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

Authors
Moreira, C; Fulgencio, N; Silva, B; Nicolet, C; Beguin, 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

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.

Role of pump hydro in electric power systems

Authors
Bessa, R; Moreira, C; Silva, B; Filipe, J; Fulgencio, N;

Publication
Journal of Physics: Conference Series

Abstract
This paper provides an overview of the expected role that variable speed hydro power plants can have in future electric power systems characterized by a massive integration of highly variable sources. Therefore, it is discussed the development of a methodology for optimising the operation of hydropower plants under increasing contribution from new renewable energy sources, addressing the participation of a hydropower plant with variable speed pumping in reserve markets. Complementarily, it is also discussed the active role variable speed generators can have in the provision of advanced frequency regulation services. © Published under licence by IOP Publishing Ltd.
