Condicionadores ativos de potência para mitigação de problemas de qualidade de ...

Os condicionadores ativos são equipamentos baseados em eletrónica de potência que permitem mitigar de forma dinâmica diversos problemas nas tensões e nas correntes do sistema elétrico, contribuindo efetivamente para a melhoria da produtividade das indústrias, reduzindo os prejuízos provocados pelos problemas de Qualidade de Energia Elétrica.

Monitorização da qualidade da energia elétrica

A monitorização da Qualidade da Energia Elétrica é uma mais-valia para os responsáveis pelas instalações elétricas, permitindo a otimização dos perfis de consumo e a identificação e prevenção de problemas.

Cloud collaborative broker for Distributed Energy Resources

Neste trabalho é apresentado um sistema de informação (SI) que pretende ajudar à colaboração de VE de modo a entrarem no mercado de energia elétrica, conseguindo que o dono do VE seja compensado, minimizando o investimento inicial na compra do VE e ajude a criar um modelo de armazenamento de energia mais amigo do ambiente. A este SI chamou-se de Broker Colaborativo ou simplesmente Broker deverá permitir ao dono...

Moby.Cockpit Project for EV seamless integration in the cooperative transport i...

Electric Vehicles (EV) are being introduced in the market, however the reduced energy storage capacity of their batteries and the lack of a high density charging infrastructure, limits their autonomy range. In order to overcome this limitation, we propose the development of a new solution for EV drivers that enables to travel longer distances. This is achieved by integrating some components of the cooperative t...

A conceptual V2G aggregation platform

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 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. With this system it is possible for the ...

Data mining approach for range prediction of electric vehicle

Our work proposal is based on the past driving data that are stored in a driver profile, and using real time information about the Electric Vehicle parameters (e.g. speed and energy stored in the batteries), combined with external parameters (e.g. condi-tions of roads, traffic, and weather), determine the range autonomy accurately, taking into account the historical driver behavior. The driver profile is based ...

Electric vehicle route recommender system

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...

Smart battery charger for electric mobility in smart grids

In this paper is presented the development of a smart batteries charger for Electric Vehicles (EVs) and Plug-in Hybrid Electric Vehicles (PHEVs), aiming their integration in Smart Grids. The batteries charging process is controlled by an appropriate control algorithm, aiming to preserve the batteries lifespan. The main features of the equipment are the mitigation of the power quality degradation and the bidirec...

Conversion of an internal combustion engine vehicle into an electric vehicle

In this paper is described the conversion of an Internal Combustion Engine (ICE) vehicle into and Electric Vehicle (EV). The main steps of this conversion are briefly described, especially the standards to legalize EVs in Portugal, and the EV elements, mainly, the electric motor and its respective controller, and the batteries with the charging system. This paper also presents the modifications performed in t...
