Electric vehicle communities for electric market
Ferreira, João C.; Afonso, João L.In this work is proposed the design of a system to create and handle an Electric Vehicle (EV) community, based on social networks collaborative approach and a credit mechanism to incentive participation and mechanism to incentive participation and divide profits. This system is part of a V2G (Vehicle-to-Grid) module that allows EV owners to be aggregated in communities and participate in the electricity market....

Exposto, Bruno Fernandes; Carneiro, H.; Pinto, J. G.; Couto, Carlos; Afonso, João L.Bruno Exposto, Helder Carneiro, J. G. Pinto, Carlos Couto, João L. Afonso, "Simulations of a current-source Shunt Active Power Filter with Carrier-Based PWM and Periodic Sampling Modulation Techniques" Proceedings of the 2011-14th European Conference on Power Electronics and Applications (EPE 2011), pp.1-8, 30 Aug. – 1 Sept., 2011.; This paper presents a Shunt Active Power Filter that is built using a current-s...
Impact of electric vehicles on power quality in a smart grid context
Monteiro, Vítor Duarte Fernandes; Gonçalves, Henrique; Afonso, João L.The large dependency of the imported fossil fuels and the soaring oil prices, makes essential the look for alternatives to the traditional people transportation system. The natural bet is the electric mobility, namely Electric Vehicles (EV), and Plug-in Hybrid Electric Vehicles (PHEV). This way, in this paper is analyzed the potential impacts of the battery charging systems on the grid power quality, in a Smart...

Pedrosa, Delfim Duarte Rolo; Pereira, Rui; Gonçalves, Henrique; Exposto, Bruno Fernandes; Monteiro, Vítor Duarte Fernandes; Pinto, J. G.The electric motors’ test benches are greatly used by electric motors manufacturers and drive system designers. In this paper it is described the conversion process of an older manually controlled test bench, in an automatic digitally controlled one with integrated data acquisition system. The renewed test bench is based in a two quadrant eddy current electromagnetic brake, in which the manual torque controller...

Exposto, Bruno Fernandes; Pinto, J. G.; Pedrosa, Delfim Duarte Rolo; Monteiro, Vítor Duarte Fernandes; Gonçalves, Henrique; Afonso, João L.In this paper are presented experimental and simulation results of a developed Current-Source Three-Phase Shunt Active Power Filter compensating the currents of a non-linear load. The Shunt Active Power Filter controller, described in detail along the paper, relies in the p-q Theory to calculate the reference compensation currents and to regulate the DC-link inductance current. The regulation of the active filt...
Comparison of current-source and voltage-source shunt active power filters for ...
Pinto, J. G.; Exposto, Bruno Fernandes; Monteiro, Vítor Duarte Fernandes; Monteiro, Luís F. C.; Couto, Carlos; Afonso, João L.This paper presents the comparison between two three-phase Shunt Active Power Filters (SAPFs), one with Current-Source Inverter (CSI) and the other with Voltage-Source Inverter (VSI), which are used to compensate current harmonics and to control reactive power. The control algorithm of both SAPFs is based on the Instantaneous Reactive Power Theory (p-q Theory). The comparison here presented focuses on the Total...
Experimental results of a developed single-phase thyristor switched capacitor
Exposto, Bruno Fernandes; Manuel, Nuno; Pinto, J. G.; Monteiro, Vítor Duarte Fernandes; Pedrosa, Delfim Duarte Rolo; Afonso, João L.In this paper are presented simulation and experimental results of a developed single-phase Thyristor Switched Capacitor (TSC), when it is compensating the power factor at the fundamental frequency (displacement power factor) of an electrical system with distorted voltage. The developed single-phase TSC can produce reactive capacitive power with 3 different values. The Thyristor Switched Capacitor is a type of ...
Smart charging system of the electric vehicle CEPIUM
Monteiro, Vítor Duarte Fernandes; Pedrosa, Delfim Duarte Rolo; Exposto, Bruno Fernandes; Ferreira, João C.; Afonso, João L.In this paper is presented the development of a smart batteries charging system for the Electric Vehicle (EV) CEPIUM, aiming the integration of EVs in the future Smart Grids. The main features of the developed charging system are the mitigation of the power quality degradation and the bidirectional operation, as Grid-to-Vehicle (G2V) and as Vehicle-to-Grid (V2G). The batteries charging process is controlled by ...
Electric vehicle route recommender system
Ferreira, João C.; Monteiro, Vítor Duarte Fernandes; Afonso, João L.This paper presents a recommender system responsible for processing information that will help the driver in the daily use of his Electric Vehicle (EV), minimizing the problem of range anxiety through a personalized range prediction and by presenting in real time relevant information about the charging stations that can be reached within the range autonomy. Given the success of recommendation systems on automat...
